Changelog
### 7.1.0
```
=========================
Breaking Changes
----------------
- `8838 <https://github.com/pytest-dev/pytest/issues/8838>`_: As per our policy, the following features have been deprecated in the 6.X series and are now
removed:
* ``pytest._fillfuncargs`` function.
* ``pytest_warning_captured`` hook - use ``pytest_warning_recorded`` instead.
* ``-k -foobar`` syntax - use ``-k 'not foobar'`` instead.
* ``-k foobar:`` syntax.
* ``pytest.collect`` module - import from ``pytest`` directly.
For more information consult
`Deprecations and Removals <https://docs.pytest.org/en/latest/deprecations.html>`__ in the docs.
- `9437 <https://github.com/pytest-dev/pytest/issues/9437>`_: Dropped support for Python 3.6, which reached `end-of-life <https://devguide.python.org/#status-of-python-branches>`__ at 2021-12-23.
Improvements
------------
- `5192 <https://github.com/pytest-dev/pytest/issues/5192>`_: Fixed test output for some data types where ``-v`` would show less information.
Also, when showing diffs for sequences, ``-q`` would produce full diffs instead of the expected diff.
- `9362 <https://github.com/pytest-dev/pytest/issues/9362>`_: pytest now avoids specialized assert formatting when it is detected that the default ``__eq__`` is overridden in ``attrs`` or ``dataclasses``.
- `9536 <https://github.com/pytest-dev/pytest/issues/9536>`_: When ``-vv`` is given on command line, show skipping and xfail reasons in full instead of truncating them to fit the terminal width.
- `9644 <https://github.com/pytest-dev/pytest/issues/9644>`_: More information about the location of resources that led Python to raise :class:`ResourceWarning` can now
be obtained by enabling :mod:`tracemalloc`.
See :ref:`resource-warnings` for more information.
- `9678 <https://github.com/pytest-dev/pytest/issues/9678>`_: More types are now accepted in the ``ids`` argument to ``pytest.mark.parametrize``.
Previously only `str`, `float`, `int` and `bool` were accepted;
now `bytes`, `complex`, `re.Pattern`, `Enum` and anything with a `__name__` are also accepted.
- `9692 <https://github.com/pytest-dev/pytest/issues/9692>`_: :func:`pytest.approx` now raises a :class:`TypeError` when given an unordered sequence (such as :class:`set`).
Note that this implies that custom classes which only implement ``__iter__`` and ``__len__`` are no longer supported as they don't guarantee order.
Bug Fixes
---------
- `8242 <https://github.com/pytest-dev/pytest/issues/8242>`_: The deprecation of raising :class:`unittest.SkipTest` to skip collection of
tests during the pytest collection phase is reverted - this is now a supported
feature again.
- `9493 <https://github.com/pytest-dev/pytest/issues/9493>`_: Symbolic link components are no longer resolved in conftest paths.
This means that if a conftest appears twice in collection tree, using symlinks, it will be executed twice.
For example, given
tests/real/conftest.py
tests/real/test_it.py
tests/link -> tests/real
running ``pytest tests`` now imports the conftest twice, once as ``tests/real/conftest.py`` and once as ``tests/link/conftest.py``.
This is a fix to match a similar change made to test collection itself in pytest 6.0 (see :pull:`6523` for details).
- `9626 <https://github.com/pytest-dev/pytest/issues/9626>`_: Fixed count of selected tests on terminal collection summary when there were errors or skipped modules.
If there were errors or skipped modules on collection, pytest would mistakenly subtract those from the selected count.
- `9645 <https://github.com/pytest-dev/pytest/issues/9645>`_: Fixed regression where ``--import-mode=importlib`` used together with :envvar:`PYTHONPATH` or :confval:`pythonpath` would cause import errors in test suites.
- `9708 <https://github.com/pytest-dev/pytest/issues/9708>`_: :fixture:`pytester` now requests a :fixture:`monkeypatch` fixture instead of creating one internally. This solves some issues with tests that involve pytest environment variables.
- `9730 <https://github.com/pytest-dev/pytest/issues/9730>`_: Malformed ``pyproject.toml`` files now produce a clearer error message.
```
### 7.0.1
```
=========================
Bug Fixes
---------
- `9608 <https://github.com/pytest-dev/pytest/issues/9608>`_: Fix invalid importing of ``importlib.readers`` in Python 3.9.
- `9610 <https://github.com/pytest-dev/pytest/issues/9610>`_: Restore `UnitTestFunction.obj` to return unbound rather than bound method.
Fixes a crash during a failed teardown in unittest TestCases with non-default `__init__`.
Regressed in pytest 7.0.0.
- `9636 <https://github.com/pytest-dev/pytest/issues/9636>`_: The ``pythonpath`` plugin was renamed to ``python_path``. This avoids a conflict with the ``pytest-pythonpath`` plugin.
- `9642 <https://github.com/pytest-dev/pytest/issues/9642>`_: Fix running tests by id with ``::`` in the parametrize portion.
- `9643 <https://github.com/pytest-dev/pytest/issues/9643>`_: Delay issuing a :class:`~pytest.PytestWarning` about diamond inheritance involving :class:`~pytest.Item` and
:class:`~pytest.Collector` so it can be filtered using :ref:`standard warning filters <warnings>`.
```
### 7.0.0
```
=========================
(**Please see the full set of changes for this release also in the 7.0.0rc1 notes below**)
Deprecations
------------
- `9488 <https://github.com/pytest-dev/pytest/issues/9488>`_: If custom subclasses of nodes like :class:`pytest.Item` override the
``__init__`` method, they should take ``**kwargs``. See
:ref:`uncooperative-constructors-deprecated` for details.
Note that a deprection warning is only emitted when there is a conflict in the
arguments pytest expected to pass. This deprecation was already part of pytest
7.0.0rc1 but wasn't documented.
Bug Fixes
---------
- `9355 <https://github.com/pytest-dev/pytest/issues/9355>`_: Fixed error message prints function decorators when using assert in Python 3.8 and above.
- `9396 <https://github.com/pytest-dev/pytest/issues/9396>`_: Ensure :attr:`pytest.Config.inifile` is available during the :func:`pytest_cmdline_main <_pytest.hookspec.pytest_cmdline_main>` hook (regression during ``7.0.0rc1``).
Improved Documentation
----------------------
- `9404 <https://github.com/pytest-dev/pytest/issues/9404>`_: Added extra documentation on alternatives to common misuses of `pytest.warns(None)` ahead of its deprecation.
- `9505 <https://github.com/pytest-dev/pytest/issues/9505>`_: Clarify where the configuration files are located. To avoid confusions documentation mentions
that configuration file is located in the root of the repository.
Trivial/Internal Changes
------------------------
- `9521 <https://github.com/pytest-dev/pytest/issues/9521>`_: Add test coverage to assertion rewrite path.
```
### 7.0.0rc1
```
============================
Breaking Changes
----------------
- `7259 <https://github.com/pytest-dev/pytest/issues/7259>`_: The :ref:`Node.reportinfo() <non-python tests>` function first return value type has been expanded from `py.path.local | str` to `os.PathLike[str] | str`.
Most plugins which refer to `reportinfo()` only define it as part of a custom :class:`pytest.Item` implementation.
Since `py.path.local` is a `os.PathLike[str]`, these plugins are unaffacted.
Plugins and users which call `reportinfo()`, use the first return value and interact with it as a `py.path.local`, would need to adjust by calling `py.path.local(fspath)`.
Although preferably, avoid the legacy `py.path.local` and use `pathlib.Path`, or use `item.location` or `item.path`, instead.
Note: pytest was not able to provide a deprecation period for this change.
- `8246 <https://github.com/pytest-dev/pytest/issues/8246>`_: ``--version`` now writes version information to ``stdout`` rather than ``stderr``.
- `8733 <https://github.com/pytest-dev/pytest/issues/8733>`_: Drop a workaround for `pyreadline <https://github.com/pyreadline/pyreadline>`__ that made it work with ``--pdb``.
The workaround was introduced in `1281 <https://github.com/pytest-dev/pytest/pull/1281>`__ in 2015, however since then
`pyreadline seems to have gone unmaintained <https://github.com/pyreadline/pyreadline/issues/58>`__, is `generating
warnings <https://github.com/pytest-dev/pytest/issues/8847>`__, and will stop working on Python 3.10.
- `9061 <https://github.com/pytest-dev/pytest/issues/9061>`_: Using :func:`pytest.approx` in a boolean context now raises an error hinting at the proper usage.
It is apparently common for users to mistakenly use ``pytest.approx`` like this:
.. code-block:: python
assert pytest.approx(actual, expected)
While the correct usage is:
.. code-block:: python
assert actual == pytest.approx(expected)
The new error message helps catch those mistakes.
- `9277 <https://github.com/pytest-dev/pytest/issues/9277>`_: The ``pytest.Instance`` collector type has been removed.
Importing ``pytest.Instance`` or ``_pytest.python.Instance`` returns a dummy type and emits a deprecation warning.
See :ref:`instance-collector-deprecation` for details.
- `9308 <https://github.com/pytest-dev/pytest/issues/9308>`_: **PytestRemovedIn7Warning deprecation warnings are now errors by default.**
Following our plan to remove deprecated features with as little disruption as
possible, all warnings of type ``PytestRemovedIn7Warning`` now generate errors
instead of warning messages by default.
**The affected features will be effectively removed in pytest 7.1**, so please consult the
:ref:`deprecations` section in the docs for directions on how to update existing code.
In the pytest ``7.0.X`` series, it is possible to change the errors back into warnings as a
stopgap measure by adding this to your ``pytest.ini`` file:
.. code-block:: ini
[pytest]
filterwarnings =
ignore::pytest.PytestRemovedIn7Warning
But this will stop working when pytest ``7.1`` is released.
**If you have concerns** about the removal of a specific feature, please add a
comment to :issue:`9308`.
Deprecations
------------
- `7259 <https://github.com/pytest-dev/pytest/issues/7259>`_: ``py.path.local`` arguments for hooks have been deprecated. See :ref:`the deprecation note <legacy-path-hooks-deprecated>` for full details.
``py.path.local`` arguments to Node constructors have been deprecated. See :ref:`the deprecation note <node-ctor-fspath-deprecation>` for full details.
.. note::
The name of the :class:`~_pytest.nodes.Node` arguments and attributes (the
new attribute being ``path``) is **the opposite** of the situation for hooks
(the old argument being ``path``).
This is an unfortunate artifact due to historical reasons, which should be
resolved in future versions as we slowly get rid of the :pypi:`py`
dependency (see :issue:`9283` for a longer discussion).
- `7469 <https://github.com/pytest-dev/pytest/issues/7469>`_: Directly constructing the following classes is now deprecated:
- ``_pytest.mark.structures.Mark``
- ``_pytest.mark.structures.MarkDecorator``
- ``_pytest.mark.structures.MarkGenerator``
- ``_pytest.python.Metafunc``
- ``_pytest.runner.CallInfo``
- ``_pytest._code.ExceptionInfo``
- ``_pytest.config.argparsing.Parser``
- ``_pytest.config.argparsing.OptionGroup``
- ``_pytest.pytester.HookRecorder``
These constructors have always been considered private, but now issue a deprecation warning, which may become a hard error in pytest 8.
- `8242 <https://github.com/pytest-dev/pytest/issues/8242>`_: Raising :class:`unittest.SkipTest` to skip collection of tests during the
pytest collection phase is deprecated. Use :func:`pytest.skip` instead.
Note: This deprecation only relates to using :class:`unittest.SkipTest` during test
collection. You are probably not doing that. Ordinary usage of
:class:`unittest.SkipTest` / :meth:`unittest.TestCase.skipTest` /
:func:`unittest.skip` in unittest test cases is fully supported.
.. note:: This deprecation has been reverted in pytest 7.1.0.
- `8315 <https://github.com/pytest-dev/pytest/issues/8315>`_: Several behaviors of :meth:`Parser.addoption <pytest.Parser.addoption>` are now
scheduled for removal in pytest 8 (deprecated since pytest 2.4.0):
- ``parser.addoption(..., help=".. %default ..")`` - use ``%(default)s`` instead.
- ``parser.addoption(..., type="int/string/float/complex")`` - use ``type=int`` etc. instead.
- `8447 <https://github.com/pytest-dev/pytest/issues/8447>`_: Defining a custom pytest node type which is both an :class:`pytest.Item <Item>` and a :class:`pytest.Collector <Collector>` (e.g. :class:`pytest.File <File>`) now issues a warning.
It was never sanely supported and triggers hard to debug errors.
See :ref:`the deprecation note <diamond-inheritance-deprecated>` for full details.
- `8592 <https://github.com/pytest-dev/pytest/issues/8592>`_: :hook:`pytest_cmdline_preparse` has been officially deprecated. It will be removed in a future release. Use :hook:`pytest_load_initial_conftests` instead.
See :ref:`the deprecation note <cmdline-preparse-deprecated>` for full details.
- `8645 <https://github.com/pytest-dev/pytest/issues/8645>`_: :func:`pytest.warns(None) <pytest.warns>` is now deprecated because many people used
it to mean "this code does not emit warnings", but it actually had the effect of
checking that the code emits at least one warning of any type - like ``pytest.warns()``
or ``pytest.warns(Warning)``.
- `8948 <https://github.com/pytest-dev/pytest/issues/8948>`_: :func:`pytest.skip(msg=...) <pytest.skip>`, :func:`pytest.fail(msg=...) <pytest.fail>` and :func:`pytest.exit(msg=...) <pytest.exit>`
signatures now accept a ``reason`` argument instead of ``msg``. Using ``msg`` still works, but is deprecated and will be removed in a future release.
This was changed for consistency with :func:`pytest.mark.skip <pytest.mark.skip>` and :func:`pytest.mark.xfail <pytest.mark.xfail>` which both accept
``reason`` as an argument.
- `8174 <https://github.com/pytest-dev/pytest/issues/8174>`_: The following changes have been made to types reachable through :attr:`pytest.ExceptionInfo.traceback`:
- The ``path`` property of ``_pytest.code.Code`` returns ``Path`` instead of ``py.path.local``.
- The ``path`` property of ``_pytest.code.TracebackEntry`` returns ``Path`` instead of ``py.path.local``.
There was no deprecation period for this change (sorry!).
Features
--------
- `5196 <https://github.com/pytest-dev/pytest/issues/5196>`_: Tests are now ordered by definition order in more cases.
In a class hierarchy, tests from base classes are now consistently ordered before tests defined on their subclasses (reverse MRO order).
- `7132 <https://github.com/pytest-dev/pytest/issues/7132>`_: Added two environment variables :envvar:`PYTEST_THEME` and :envvar:`PYTEST_THEME_MODE` to let the users customize the pygments theme used.
- `7259 <https://github.com/pytest-dev/pytest/issues/7259>`_: Added :meth:`cache.mkdir() <pytest.Cache.mkdir>`, which is similar to the existing :meth:`cache.makedir() <pytest.Cache.makedir>`,
but returns a :class:`pathlib.Path` instead of a legacy ``py.path.local``.
Added a ``paths`` type to :meth:`parser.addini() <pytest.Parser.addini>`,
as in ``parser.addini("mypaths", "my paths", type="paths")``,
which is similar to the existing ``pathlist``,
but returns a list of :class:`pathlib.Path` instead of legacy ``py.path.local``.
- `7469 <https://github.com/pytest-dev/pytest/issues/7469>`_: The types of objects used in pytest's API are now exported so they may be used in type annotations.
The newly-exported types are:
- ``pytest.Config`` for :class:`Config <pytest.Config>`.
- ``pytest.Mark`` for :class:`marks <pytest.Mark>`.
- ``pytest.MarkDecorator`` for :class:`mark decorators <pytest.MarkDecorator>`.
- ``pytest.MarkGenerator`` for the :class:`pytest.mark <pytest.MarkGenerator>` singleton.
- ``pytest.Metafunc`` for the :class:`metafunc <pytest.MarkGenerator>` argument to the :hook:`pytest_generate_tests` hook.
- ``pytest.CallInfo`` for the :class:`CallInfo <pytest.CallInfo>` type passed to various hooks.
- ``pytest.PytestPluginManager`` for :class:`PytestPluginManager <pytest.PytestPluginManager>`.
- ``pytest.ExceptionInfo`` for the :class:`ExceptionInfo <pytest.ExceptionInfo>` type returned from :func:`pytest.raises` and passed to various hooks.
- ``pytest.Parser`` for the :class:`Parser <pytest.Parser>` type passed to the :hook:`pytest_addoption` hook.
- ``pytest.OptionGroup`` for the :class:`OptionGroup <pytest.OptionGroup>` type returned from the :func:`parser.addgroup <pytest.Parser.getgroup>` method.
- ``pytest.HookRecorder`` for the :class:`HookRecorder <pytest.HookRecorder>` type returned from :class:`~pytest.Pytester`.
- ``pytest.RecordedHookCall`` for the :class:`RecordedHookCall <pytest.HookRecorder>` type returned from :class:`~pytest.HookRecorder`.
- ``pytest.RunResult`` for the :class:`RunResult <pytest.RunResult>` type returned from :class:`~pytest.Pytester`.
- ``pytest.LineMatcher`` for the :class:`LineMatcher <pytest.RunResult>` type used in :class:`~pytest.RunResult` and others.
- ``pytest.TestReport`` for the :class:`TestReport <pytest.TestReport>` type used in various hooks.
- ``pytest.CollectReport`` for the :class:`CollectReport <pytest.CollectReport>` type used in various hooks.
Constructing most of them directly is not supported; they are only meant for use in type annotations.
Doing so will emit a deprecation warning, and may become a hard-error in pytest 8.0.
Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy.
- `7856 <https://github.com/pytest-dev/pytest/issues/7856>`_: :ref:`--import-mode=importlib <import-modes>` now works with features that
depend on modules being on :py:data:`sys.modules`, such as :mod:`pickle` and :mod:`dataclasses`.
- `8144 <https://github.com/pytest-dev/pytest/issues/8144>`_: The following hooks now receive an additional ``pathlib.Path`` argument, equivalent to an existing ``py.path.local`` argument:
- :hook:`pytest_ignore_collect` - The ``collection_path`` parameter (equivalent to existing ``path`` parameter).
- :hook:`pytest_collect_file` - The ``file_path`` parameter (equivalent to existing ``path`` parameter).
- :hook:`pytest_pycollect_makemodule` - The ``module_path`` parameter (equivalent to existing ``path`` parameter).
- :hook:`pytest_report_header` - The ``start_path`` parameter (equivalent to existing ``startdir`` parameter).
- :hook:`pytest_report_collectionfinish` - The ``start_path`` parameter (equivalent to existing ``startdir`` parameter).
.. note::
The name of the :class:`~_pytest.nodes.Node` arguments and attributes (the
new attribute being ``path``) is **the opposite** of the situation for hooks
(the old argument being ``path``).
This is an unfortunate artifact due to historical reasons, which should be
resolved in future versions as we slowly get rid of the :pypi:`py`
dependency (see :issue:`9283` for a longer discussion).
- `8251 <https://github.com/pytest-dev/pytest/issues/8251>`_: Implement ``Node.path`` as a ``pathlib.Path``. Both the old ``fspath`` and this new attribute gets set no matter whether ``path`` or ``fspath`` (deprecated) is passed to the constructor. It is a replacement for the ``fspath`` attribute (which represents the same path as ``py.path.local``). While ``fspath`` is not deprecated yet
due to the ongoing migration of methods like :meth:`~_pytest.Item.reportinfo`, we expect to deprecate it in a future release.
.. note::
The name of the :class:`~_pytest.nodes.Node` arguments and attributes (the
new attribute being ``path``) is **the opposite** of the situation for hooks
(the old argument being ``path``).
This is an unfortunate artifact due to historical reasons, which should be
resolved in future versions as we slowly get rid of the :pypi:`py`
dependency (see :issue:`9283` for a longer discussion).
- `8421 <https://github.com/pytest-dev/pytest/issues/8421>`_: :func:`pytest.approx` now works on :class:`~decimal.Decimal` within mappings/dicts and sequences/lists.
- `8606 <https://github.com/pytest-dev/pytest/issues/8606>`_: pytest invocations with ``--fixtures-per-test`` and ``--fixtures`` have been enriched with:
- Fixture location path printed with the fixture name.
- First section of the fixture's docstring printed under the fixture name.
- Whole of fixture's docstring printed under the fixture name using ``--verbose`` option.
- `8761 <https://github.com/pytest-dev/pytest/issues/8761>`_: New :ref:`version-tuple` attribute, which makes it simpler for users to do something depending on the pytest version (such as declaring hooks which are introduced in later versions).
- `8789 <https://github.com/pytest-dev/pytest/issues/8789>`_: Switch TOML parser from ``toml`` to ``tomli`` for TOML v1.0.0 support in ``pyproject.toml``.
- `8920 <https://github.com/pytest-dev/pytest/issues/8920>`_: Added :class:`pytest.Stash`, a facility for plugins to store their data on :class:`~pytest.Config` and :class:`~_pytest.nodes.Node`\s in a type-safe and conflict-free manner.
See :ref:`plugin-stash` for details.
- `8953 <https://github.com/pytest-dev/pytest/issues/8953>`_: :class:`RunResult <_pytest.pytester.RunResult>` method :meth:`assert_outcomes <_pytest.pytester.RunResult.assert_outcomes>` now accepts a
``warnings`` argument to assert the total number of warnings captured.
- `8954 <https://github.com/pytest-dev/pytest/issues/8954>`_: ``--debug`` flag now accepts a :class:`str` file to route debug logs into, remains defaulted to `pytestdebug.log`.
- `9023 <https://github.com/pytest-dev/pytest/issues/9023>`_: Full diffs are now always shown for equality assertions of iterables when
`CI` or ``BUILD_NUMBER`` is found in the environment, even when ``-v`` isn't
used.
- `9113 <https://github.com/pytest-dev/pytest/issues/9113>`_: :class:`RunResult <_pytest.pytester.RunResult>` method :meth:`assert_outcomes <_pytest.pytester.RunResult.assert_outcomes>` now accepts a
``deselected`` argument to assert the total number of deselected tests.
- `9114 <https://github.com/pytest-dev/pytest/issues/9114>`_: Added :confval:`pythonpath` setting that adds listed paths to :data:`sys.path` for the duration of the test session. If you currently use the pytest-pythonpath or pytest-srcpaths plugins, you should be able to replace them with built-in `pythonpath` setting.
Improvements
------------
- `7480 <https://github.com/pytest-dev/pytest/issues/7480>`_: A deprecation scheduled to be removed in a major version X (e.g. pytest 7, 8, 9, ...) now uses warning category `PytestRemovedInXWarning`,
a subclass of :class:`~pytest.PytestDeprecationWarning`,
instead of :class:`PytestDeprecationWarning` directly.
See :ref:`backwards-compatibility` for more details.
- `7864 <https://github.com/pytest-dev/pytest/issues/7864>`_: Improved error messages when parsing warning filters.
Previously pytest would show an internal traceback, which besides being ugly sometimes would hide the cause
of the problem (for example an ``ImportError`` while importing a specific warning type).
- `8335 <https://github.com/pytest-dev/pytest/issues/8335>`_: Improved :func:`pytest.approx` assertion messages for sequences of numbers.
The assertion messages now dumps a table with the index and the error of each diff.
Example::
> assert [1, 2, 3, 4] == pytest.approx([1, 3, 3, 5])
E assert comparison failed for 2 values:
E Index | Obtained | Expected
E 1 | 2 | 3 +- 3.0e-06
E 3 | 4 | 5 +- 5.0e-06
- `8403 <https://github.com/pytest-dev/pytest/issues/8403>`_: By default, pytest will truncate long strings in assert errors so they don't clutter the output too much,
currently at ``240`` characters by default.
However, in some cases the longer output helps, or is even crucial, to diagnose a failure. Using ``-v`` will
now increase the truncation threshold to ``2400`` characters, and ``-vv`` or higher will disable truncation entirely.
- `8509 <https://github.com/pytest-dev/pytest/issues/8509>`_: Fixed issue where :meth:`unittest.TestCase.setUpClass` is not called when a test has `/` in its name since pytest 6.2.0.
This refers to the path part in pytest node IDs, e.g. ``TestClass::test_it`` in the node ID ``tests/test_file.py::TestClass::test_it``.
Now, instead of assuming that the test name does not contain ``/``, it is assumed that test path does not contain ``::``. We plan to hopefully make both of these work in the future.
- `8803 <https://github.com/pytest-dev/pytest/issues/8803>`_: It is now possible to add colors to custom log levels on cli log.
By using :func:`add_color_level <_pytest.logging.add_color_level>` from a ``pytest_configure`` hook, colors can be added::
logging_plugin = config.pluginmanager.get_plugin('logging-plugin')
logging_plugin.log_cli_handler.formatter.add_color_level(logging.INFO, 'cyan')
logging_plugin.log_cli_handler.formatter.add_color_level(logging.SPAM, 'blue')
See :ref:`log_colors` for more information.
- `8822 <https://github.com/pytest-dev/pytest/issues/8822>`_: When showing fixture paths in `--fixtures` or `--fixtures-by-test`, fixtures coming from pytest itself now display an elided path, rather than the full path to the file in the `site-packages` directory.
- `8898 <https://github.com/pytest-dev/pytest/issues/8898>`_: Complex numbers are now treated like floats and integers when generating parameterization IDs.
- `9062 <https://github.com/pytest-dev/pytest/issues/9062>`_: ``--stepwise-skip`` now implicitly enables ``--stepwise`` and can be used on its own.
- `9205 <https://github.com/pytest-dev/pytest/issues/9205>`_: :meth:`pytest.Cache.set` now preserves key order when saving dicts.
Bug Fixes
---------
- `7124 <https://github.com/pytest-dev/pytest/issues/7124>`_: Fixed an issue where ``__main__.py`` would raise an ``ImportError`` when ``--doctest-modules`` was provided.
- `8061 <https://github.com/pytest-dev/pytest/issues/8061>`_: Fixed failing ``staticmethod`` test cases if they are inherited from a parent test class.
- `8192 <https://github.com/pytest-dev/pytest/issues/8192>`_: ``testdir.makefile`` now silently accepts values which don't start with ``.`` to maintain backward compatibility with older pytest versions.
``pytester.makefile`` now issues a clearer error if the ``.`` is missing in the ``ext`` argument.
- `8258 <https://github.com/pytest-dev/pytest/issues/8258>`_: Fixed issue where pytest's ``faulthandler`` support would not dump traceback on crashes
if the :mod:`faulthandler` module was already enabled during pytest startup (using
``python -X dev -m pytest`` for example).
- `8317 <https://github.com/pytest-dev/pytest/issues/8317>`_: Fixed an issue where illegal directory characters derived from ``getpass.getuser()`` raised an ``OSError``.
- `8367 <https://github.com/pytest-dev/pytest/issues/8367>`_: Fix ``Class.from_parent`` so it forwards extra keyword arguments to the constructor.
- `8377 <https://github.com/pytest-dev/pytest/issues/8377>`_: The test selection options ``pytest -k`` and ``pytest -m`` now support matching
names containing forward slash (``/``) characters.
- `8384 <https://github.com/pytest-dev/pytest/issues/8384>`_: The ``pytest.mark.skip`` decorator now correctly handles its arguments. When the ``reason`` argument is accidentally given both positional and as a keyword (e.g. because it was confused with ``skipif``), a ``TypeError`` now occurs. Before, such tests were silently skipped, and the positional argument ignored. Additionally, ``reason`` is now documented correctly as positional or keyword (rather than keyword-only).
- `8394 <https://github.com/pytest-dev/pytest/issues/8394>`_: Use private names for internal fixtures that handle classic setup/teardown so that they don't show up with the default ``--fixtures`` invocation (but they still show up with ``--fixtures -v``).
- `8456 <https://github.com/pytest-dev/pytest/issues/8456>`_: The :confval:`required_plugins` config option now works correctly when pre-releases of plugins are installed, rather than falsely claiming that those plugins aren't installed at all.
- `8464 <https://github.com/pytest-dev/pytest/issues/8464>`_: ``-c <config file>`` now also properly defines ``rootdir`` as the directory that contains ``<config file>``.
- `8503 <https://github.com/pytest-dev/pytest/issues/8503>`_: :meth:`pytest.MonkeyPatch.syspath_prepend` no longer fails when
``setuptools`` is not installed.
It now only calls :func:`pkg_resources.fixup_namespace_packages` if
``pkg_resources`` was previously imported, because it is not needed otherwise.
- `8548 <https://github.com/pytest-dev/pytest/issues/8548>`_: Introduce fix to handle precision width in ``log-cli-format`` in turn to fix output coloring for certain formats.
- `8796 <https://github.com/pytest-dev/pytest/issues/8796>`_: Fixed internal error when skipping doctests.
- `8983 <https://github.com/pytest-dev/pytest/issues/8983>`_: The test selection options ``pytest -k`` and ``pytest -m`` now support matching names containing backslash (`\\`) characters.
Backslashes are treated literally, not as escape characters (the values being matched against are already escaped).
- `8990 <https://github.com/pytest-dev/pytest/issues/8990>`_: Fix `pytest -vv` crashing with an internal exception `AttributeError: 'str' object has no attribute 'relative_to'` in some cases.
- `9077 <https://github.com/pytest-dev/pytest/issues/9077>`_: Fixed confusing error message when ``request.fspath`` / ``request.path`` was accessed from a session-scoped fixture.
- `9131 <https://github.com/pytest-dev/pytest/issues/9131>`_: Fixed the URL used by ``--pastebin`` to use `bpa.st <http://bpa.st>`__.
- `9163 <https://github.com/pytest-dev/pytest/issues/9163>`_: The end line number and end column offset are now properly set for rewritten assert statements.
- `9169 <https://github.com/pytest-dev/pytest/issues/9169>`_: Support for the ``files`` API from ``importlib.resources`` within rewritten files.
- `9272 <https://github.com/pytest-dev/pytest/issues/9272>`_: The nose compatibility module-level fixtures `setup()` and `teardown()` are now only called once per module, instead of for each test function.
They are now called even if object-level `setup`/`teardown` is defined.
Improved Documentation
----------------------
- `4320 <https://github.com/pytest-dev/pytest/issues/4320>`_: Improved docs for `pytester.copy_example`.
- `5105 <https://github.com/pytest-dev/pytest/issues/5105>`_: Add automatically generated :ref:`plugin-list`. The list is updated on a periodic schedule.
- `8337 <https://github.com/pytest-dev/pytest/issues/8337>`_: Recommend `numpy.testing <https://numpy.org/doc/stable/reference/routines.testing.html>`__ module on :func:`pytest.approx` documentation.
- `8655 <https://github.com/pytest-dev/pytest/issues/8655>`_: Help text for ``--pdbcls`` more accurately reflects the option's behavior.
- `9210 <https://github.com/pytest-dev/pytest/issues/9210>`_: Remove incorrect docs about ``confcutdir`` being a configuration option: it can only be set through the ``--confcutdir`` command-line option.
- `9242 <https://github.com/pytest-dev/pytest/issues/9242>`_: Upgrade readthedocs configuration to use a `newer Ubuntu version <https://blog.readthedocs.com/new-build-specification/>`__` with better unicode support for PDF docs.
- `9341 <https://github.com/pytest-dev/pytest/issues/9341>`_: Various methods commonly used for :ref:`non-python tests` are now correctly documented in the reference docs. They were undocumented previously.
Trivial/Internal Changes
------------------------
- `8133 <https://github.com/pytest-dev/pytest/issues/8133>`_: Migrate to ``setuptools_scm`` 6.x to use ``SETUPTOOLS_SCM_PRETEND_VERSION_FOR_PYTEST`` for more robust release tooling.
- `8174 <https://github.com/pytest-dev/pytest/issues/8174>`_: The following changes have been made to internal pytest types/functions:
- The ``_pytest.code.getfslineno()`` function returns ``Path`` instead of ``py.path.local``.
- The ``_pytest.python.path_matches_patterns()`` function takes ``Path`` instead of ``py.path.local``.
- The ``_pytest._code.Traceback.cut()`` function accepts any ``os.PathLike[str]``, not just ``py.path.local``.
- `8248 <https://github.com/pytest-dev/pytest/issues/8248>`_: Internal Restructure: let ``python.PyObjMixin`` inherit from ``nodes.Node`` to carry over typing information.
- `8432 <https://github.com/pytest-dev/pytest/issues/8432>`_: Improve error message when :func:`pytest.skip` is used at module level without passing `allow_module_level=True`.
- `8818 <https://github.com/pytest-dev/pytest/issues/8818>`_: Ensure ``regendoc`` opts out of ``TOX_ENV`` cachedir selection to ensure independent example test runs.
- `8913 <https://github.com/pytest-dev/pytest/issues/8913>`_: The private ``CallSpec2._arg2scopenum`` attribute has been removed after an internal refactoring.
- `8967 <https://github.com/pytest-dev/pytest/issues/8967>`_: :hook:`pytest_assertion_pass` is no longer considered experimental and
future changes to it will be considered more carefully.
- `9202 <https://github.com/pytest-dev/pytest/issues/9202>`_: Add github action to upload coverage report to codecov instead of bash uploader.
- `9225 <https://github.com/pytest-dev/pytest/issues/9225>`_: Changed the command used to create sdist and wheel artifacts: using the build package instead of setup.py.
- `9351 <https://github.com/pytest-dev/pytest/issues/9351>`_: Correct minor typos in doc/en/example/special.rst.
```
### 6.2.5
```
=========================
Trivial/Internal Changes
------------------------
- :issue:`8494`: Python 3.10 is now supported.
- :issue:`9040`: Enable compatibility with ``pluggy 1.0`` or later.
```
### 6.2.4
```
=========================
Bug Fixes
---------
- :issue:`8539`: Fixed assertion rewriting on Python 3.10.
```
### 6.2.3
```
=========================
Bug Fixes
---------
- :issue:`8414`: pytest used to create directories under ``/tmp`` with world-readable
permissions. This means that any user in the system was able to read
information written by tests in temporary directories (such as those created by
the ``tmp_path``/``tmpdir`` fixture). Now the directories are created with
private permissions.
pytest used to silently use a pre-existing ``/tmp/pytest-of-<username>`` directory,
even if owned by another user. This means another user could pre-create such a
directory and gain control of another user's temporary directory. Now such a
condition results in an error.
```
### 6.2.2
```
=========================
Bug Fixes
---------
- :issue:`8152`: Fixed "(<Skipped instance>)" being shown as a skip reason in the verbose test summary line when the reason is empty.
- :issue:`8249`: Fix the ``faulthandler`` plugin for occasions when running with ``twisted.logger`` and using ``pytest --capture=no``.
```
### 6.2.1
```
=========================
Bug Fixes
---------
- :issue:`7678`: Fixed bug where ``ImportPathMismatchError`` would be raised for files compiled in
the host and loaded later from an UNC mounted path (Windows).
- :issue:`8132`: Fixed regression in ``approx``: in 6.2.0 ``approx`` no longer raises
``TypeError`` when dealing with non-numeric types, falling back to normal comparison.
Before 6.2.0, array types like tf.DeviceArray fell through to the scalar case,
and happened to compare correctly to a scalar if they had only one element.
After 6.2.0, these types began failing, because they inherited neither from
standard Python number hierarchy nor from ``numpy.ndarray``.
``approx`` now converts arguments to ``numpy.ndarray`` if they expose the array
protocol and are not scalars. This treats array-like objects like numpy arrays,
regardless of size.
```
### 6.2.0
```
=========================
Breaking Changes
----------------
- :issue:`7808`: pytest now supports python3.6+ only.
Deprecations
------------
- :issue:`7469`: Directly constructing/calling the following classes/functions is now deprecated:
- ``_pytest.cacheprovider.Cache``
- ``_pytest.cacheprovider.Cache.for_config()``
- ``_pytest.cacheprovider.Cache.clear_cache()``
- ``_pytest.cacheprovider.Cache.cache_dir_from_config()``
- ``_pytest.capture.CaptureFixture``
- ``_pytest.fixtures.FixtureRequest``
- ``_pytest.fixtures.SubRequest``
- ``_pytest.logging.LogCaptureFixture``
- ``_pytest.pytester.Pytester``
- ``_pytest.pytester.Testdir``
- ``_pytest.recwarn.WarningsRecorder``
- ``_pytest.recwarn.WarningsChecker``
- ``_pytest.tmpdir.TempPathFactory``
- ``_pytest.tmpdir.TempdirFactory``
These have always been considered private, but now issue a deprecation warning, which may become a hard error in pytest 8.0.0.
- :issue:`7530`: The ``--strict`` command-line option has been deprecated, use ``--strict-markers`` instead.
We have plans to maybe in the future to reintroduce ``--strict`` and make it an encompassing flag for all strictness
related options (``--strict-markers`` and ``--strict-config`` at the moment, more might be introduced in the future).
- :issue:`7988`: The ``pytest.yield_fixture`` decorator/function is now deprecated. Use :func:`pytest.fixture` instead.
``yield_fixture`` has been an alias for ``fixture`` for a very long time, so can be search/replaced safely.
Features
--------
- :issue:`5299`: pytest now warns about unraisable exceptions and unhandled thread exceptions that occur in tests on Python>=3.8.
See :ref:`unraisable` for more information.
- :issue:`7425`: New :fixture:`pytester` fixture, which is identical to :fixture:`testdir` but its methods return :class:`pathlib.Path` when appropriate instead of ``py.path.local``.
This is part of the movement to use :class:`pathlib.Path` objects internally, in order to remove the dependency to ``py`` in the future.
Internally, the old :class:`Testdir <_pytest.pytester.Testdir>` is now a thin wrapper around :class:`Pytester <_pytest.pytester.Pytester>`, preserving the old interface.
- :issue:`7695`: A new hook was added, `pytest_markeval_namespace` which should return a dictionary.
This dictionary will be used to augment the "global" variables available to evaluate skipif/xfail/xpass markers.
Pseudo example
``conftest.py``:
.. code-block:: python
def pytest_markeval_namespace():
return {"color": "red"}
``test_func.py``:
.. code-block:: python
pytest.mark.skipif("color == 'blue'", reason="Color is not red")
def test_func():
assert False
- :issue:`8006`: It is now possible to construct a :class:`~pytest.MonkeyPatch` object directly as ``pytest.MonkeyPatch()``,
in cases when the :fixture:`monkeypatch` fixture cannot be used. Previously some users imported it
from the private `_pytest.monkeypatch.MonkeyPatch` namespace.
Additionally, :meth:`MonkeyPatch.context <pytest.MonkeyPatch.context>` is now a classmethod,
and can be used as ``with MonkeyPatch.context() as mp: ...``. This is the recommended way to use
``MonkeyPatch`` directly, since unlike the ``monkeypatch`` fixture, an instance created directly
is not ``undo()``-ed automatically.
Improvements
------------
- :issue:`1265`: Added an ``__str__`` implementation to the :class:`~pytest.pytester.LineMatcher` class which is returned from ``pytester.run_pytest().stdout`` and similar. It returns the entire output, like the existing ``str()`` method.
- :issue:`2044`: Verbose mode now shows the reason that a test was skipped in the test's terminal line after the "SKIPPED", "XFAIL" or "XPASS".
- :issue:`7469` The types of builtin pytest fixtures are now exported so they may be used in type annotations of test functions.
The newly-exported types are:
- ``pytest.FixtureRequest`` for the :fixture:`request` fixture.
- ``pytest.Cache`` for the :fixture:`cache` fixture.
- ``pytest.CaptureFixture[str]`` for the :fixture:`capfd` and :fixture:`capsys` fixtures.
- ``pytest.CaptureFixture[bytes]`` for the :fixture:`capfdbinary` and :fixture:`capsysbinary` fixtures.
- ``pytest.LogCaptureFixture`` for the :fixture:`caplog` fixture.
- ``pytest.Pytester`` for the :fixture:`pytester` fixture.
- ``pytest.Testdir`` for the :fixture:`testdir` fixture.
- ``pytest.TempdirFactory`` for the :fixture:`tmpdir_factory` fixture.
- ``pytest.TempPathFactory`` for the :fixture:`tmp_path_factory` fixture.
- ``pytest.MonkeyPatch`` for the :fixture:`monkeypatch` fixture.
- ``pytest.WarningsRecorder`` for the :fixture:`recwarn` fixture.
Constructing them is not supported (except for `MonkeyPatch`); they are only meant for use in type annotations.
Doing so will emit a deprecation warning, and may become a hard-error in pytest 8.0.
Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy.
- :issue:`7527`: When a comparison between :func:`namedtuple <collections.namedtuple>` instances of the same type fails, pytest now shows the differing field names (possibly nested) instead of their indexes.
- :issue:`7615`: :meth:`Node.warn <_pytest.nodes.Node.warn>` now permits any subclass of :class:`Warning`, not just :class:`PytestWarning <pytest.PytestWarning>`.
- :issue:`7701`: Improved reporting when using ``--collected-only``. It will now show the number of collected tests in the summary stats.
- :issue:`7710`: Use strict equality comparison for non-numeric types in :func:`pytest.approx` instead of
raising :class:`TypeError`.
This was the undocumented behavior before 3.7, but is now officially a supported feature.
- :issue:`7938`: New ``--sw-skip`` argument which is a shorthand for ``--stepwise-skip``.
- :issue:`8023`: Added ``'node_modules'`` to default value for :confval:`norecursedirs`.
- :issue:`8032`: :meth:`doClassCleanups <unittest.TestCase.doClassCleanups>` (introduced in :mod:`unittest` in Python and 3.8) is now called appropriately.
Bug Fixes
---------
- :issue:`4824`: Fixed quadratic behavior and improved performance of collection of items using autouse fixtures and xunit fixtures.
- :issue:`7758`: Fixed an issue where some files in packages are getting lost from ``--lf`` even though they contain tests that failed. Regressed in pytest 5.4.0.
- :issue:`7911`: Directories created by by :fixture:`tmp_path` and :fixture:`tmpdir` are now considered stale after 3 days without modification (previous value was 3 hours) to avoid deleting directories still in use in long running test suites.
- :issue:`7913`: Fixed a crash or hang in :meth:`pytester.spawn <_pytest.pytester.Pytester.spawn>` when the :mod:`readline` module is involved.
- :issue:`7951`: Fixed handling of recursive symlinks when collecting tests.
- :issue:`7981`: Fixed symlinked directories not being followed during collection. Regressed in pytest 6.1.0.
- :issue:`8016`: Fixed only one doctest being collected when using ``pytest --doctest-modules path/to/an/__init__.py``.
Improved Documentation
----------------------
- :issue:`7429`: Add more information and use cases about skipping doctests.
- :issue:`7780`: Classes which should not be inherited from are now marked ``final class`` in the API reference.
- :issue:`7872`: ``_pytest.config.argparsing.Parser.addini()`` accepts explicit ``None`` and ``"string"``.
- :issue:`7878`: In pull request section, ask to commit after editing changelog and authors file.
Trivial/Internal Changes
------------------------
- :issue:`7802`: The ``attrs`` dependency requirement is now >=19.2.0 instead of >=17.4.0.
- :issue:`8014`: `.pyc` files created by pytest's assertion rewriting now conform to the newer :pep:`552` format on Python>=3.7.
(These files are internal and only interpreted by pytest itself.)
```
### 6.1.2
```
=========================
Bug Fixes
---------
- :issue:`7758`: Fixed an issue where some files in packages are getting lost from ``--lf`` even though they contain tests that failed. Regressed in pytest 5.4.0.
- :issue:`7911`: Directories created by `tmpdir` are now considered stale after 3 days without modification (previous value was 3 hours) to avoid deleting directories still in use in long running test suites.
Improved Documentation
----------------------
- :issue:`7815`: Improve deprecation warning message for ``pytest._fillfuncargs()``.
```
### 6.1.1
```
=========================
Bug Fixes
---------
- :issue:`7807`: Fixed regression in pytest 6.1.0 causing incorrect rootdir to be determined in some non-trivial cases where parent directories have config files as well.
- :issue:`7814`: Fixed crash in header reporting when :confval:`testpaths` is used and contains absolute paths (regression in 6.1.0).
```
### 6.1.0
```
=========================
Breaking Changes
----------------
- :issue:`5585`: As per our policy, the following features which have been deprecated in the 5.X series are now
removed:
* The ``funcargnames`` read-only property of ``FixtureRequest``, ``Metafunc``, and ``Function`` classes. Use ``fixturenames`` attribute.
* ``pytest.fixture`` no longer supports positional arguments, pass all arguments by keyword instead.
* Direct construction of ``Node`` subclasses now raise an error, use ``from_parent`` instead.
* The default value for ``junit_family`` has changed to ``xunit2``. If you require the old format, add ``junit_family=xunit1`` to your configuration file.
* The ``TerminalReporter`` no longer has a ``writer`` attribute. Plugin authors may use the public functions of the ``TerminalReporter`` instead of accessing the ``TerminalWriter`` object directly.
* The ``--result-log`` option has been removed. Users are recommended to use the `pytest-reportlog <https://github.com/pytest-dev/pytest-reportlog>`__ plugin instead.
For more information consult :std:doc:`deprecations` in the docs.
Deprecations
------------
- :issue:`6981`: The ``pytest.collect`` module is deprecated: all its names can be imported from ``pytest`` directly.
- :issue:`7097`: The ``pytest._fillfuncargs`` function is deprecated. This function was kept
for backward compatibility with an older plugin.
It's functionality is not meant to be used directly, but if you must replace
it, use `function._request._fillfixtures()` instead, though note this is not
a public API and may break in the future.
- :issue:`7210`: The special ``-k '-expr'`` syntax to ``-k`` is deprecated. Use ``-k 'not expr'``
instead.
The special ``-k 'expr:'`` syntax to ``-k`` is deprecated. Please open an issue
if you use this and want a replacement.
- :issue:`7255`: The :hook:`pytest_warning_captured` hook is deprecated in favor
of :hook:`pytest_warning_recorded`, and will be removed in a future version.
- :issue:`7648`: The ``gethookproxy()`` and ``isinitpath()`` methods of ``FSCollector`` and ``Package`` are deprecated;
use ``self.session.gethookproxy()`` and ``self.session.isinitpath()`` instead.
This should work on all pytest versions.
Features
--------
- :issue:`7667`: New ``--durations-min`` command-line flag controls the minimal duration for inclusion in the slowest list of tests shown by ``--durations``. Previously this was hard-coded to ``0.005s``.
Improvements
------------
- :issue:`6681`: Internal pytest warnings issued during the early stages of initialization are now properly handled and can filtered through :confval:`filterwarnings` or ``--pythonwarnings/-W``.
This also fixes a number of long standing issues: :issue:`2891`, :issue:`7620`, :issue:`7426`.
- :issue:`7572`: When a plugin listed in ``required_plugins`` is missing or an unknown config key is used with ``--strict-config``, a simple error message is now shown instead of a stacktrace.
- :issue:`7685`: Added two new attributes :attr:`rootpath <_pytest.config.Config.rootpath>` and :attr:`inipath <_pytest.config.Config.inipath>` to :class:`Config <_pytest.config.Config>`.
These attributes are :class:`pathlib.Path` versions of the existing :attr:`rootdir <_pytest.config.Config.rootdir>` and :attr:`inifile <_pytest.config.Config.inifile>` attributes,
and should be preferred over them when possible.
- :issue:`7780`: Public classes which are not designed to be inherited from are now marked :func:`final <typing.final>`.
Code which inherits from these classes will trigger a type-checking (e.g. mypy) error, but will still work in runtime.
Currently the ``final`` designation does not appear in the API Reference but hopefully will in the future.
Bug Fixes
---------
- :issue:`1953`: Fixed error when overwriting a parametrized fixture, while also reusing the super fixture value.
.. code-block:: python
conftest.py
import pytest
pytest.fixture(params=[1, 2])
def foo(request):
return request.param
test_foo.py
import pytest
pytest.fixture
def foo(foo):
return foo * 2
- :issue:`4984`: Fixed an internal error crash with ``IndexError: list index out of range`` when
collecting a module which starts with a decorated function, the decorator
raises, and assertion rewriting is enabled.
- :issue:`7591`: pylint shouldn't complain anymore about unimplemented abstract methods when inheriting from :ref:`File <non-python tests>`.
- :issue:`7628`: Fixed test collection when a full path without a drive letter was passed to pytest on Windows (for example ``\projects\tests\test.py`` instead of ``c:\projects\tests\pytest.py``).
- :issue:`7638`: Fix handling of command-line options that appear as paths but trigger an OS-level syntax error on Windows, such as the options used internally by ``pytest-xdist``.
- :issue:`7742`: Fixed INTERNALERROR when accessing locals / globals with faulty ``exec``.
Improved Documentation
----------------------
- :issue:`1477`: Removed faq.rst and its reference in contents.rst.
Trivial/Internal Changes
------------------------
- :issue:`7536`: The internal ``junitxml`` plugin has rewritten to use ``xml.etree.ElementTree``.
The order of attributes in XML elements might differ. Some unneeded escaping is
no longer performed.
- :issue:`7587`: The dependency on the ``more-itertools`` package has been removed.
- :issue:`7631`: The result type of :meth:`capfd.readouterr() <_pytest.capture.CaptureFixture.readouterr>` (and similar) is no longer a namedtuple,
but should behave like one in all respects. This was done for technical reasons.
- :issue:`7671`: When collecting tests, pytest finds test classes and functions by examining the
attributes of python objects (modules, classes and instances). To speed up this
process, pytest now ignores builtin attributes (like ``__class__``,
``__delattr__`` and ``__new__``) without consulting the :confval:`python_classes` and
:confval:`python_functions` configuration options and without passing them to plugins
using the :hook:`pytest_pycollect_makeitem` hook.
```
### 6.0.2
```
=========================
Bug Fixes
---------
- :issue:`7148`: Fixed ``--log-cli`` potentially causing unrelated ``print`` output to be swallowed.
- :issue:`7672`: Fixed log-capturing level restored incorrectly if ``caplog.set_level`` is called more than once.
- :issue:`7686`: Fixed `NotSetType.token` being used as the parameter ID when the parametrization list is empty.
Regressed in pytest 6.0.0.
- :issue:`7707`: Fix internal error when handling some exceptions that contain multiple lines or the style uses multiple lines (``--tb=line`` for example).
```
### 6.0.1
```
=========================
Bug Fixes
---------
- :issue:`7394`: Passing an empty ``help`` value to ``Parser.add_option`` is now accepted instead of crashing when running ``pytest --help``.
Passing ``None`` raises a more informative ``TypeError``.
- :issue:`7558`: Fix pylint ``not-callable`` lint on ``pytest.mark.parametrize()`` and the other builtin marks:
``skip``, ``skipif``, ``xfail``, ``usefixtures``, ``filterwarnings``.
- :issue:`7559`: Fix regression in plugins using ``TestReport.longreprtext`` (such as ``pytest-html``) when ``TestReport.longrepr`` is not a string.
- :issue:`7569`: Fix logging capture handler's level not reset on teardown after a call to ``caplog.set_level()``.
```
### 6.0.0
```
=========================
(**Please see the full set of changes for this release also in the 6.0.0rc1 notes below**)
Breaking Changes
----------------
- :issue:`5584`: **PytestDeprecationWarning are now errors by default.**
Following our plan to remove deprecated features with as little disruption as
possible, all warnings of type ``PytestDeprecationWarning`` now generate errors
instead of warning messages.
**The affected features will be effectively removed in pytest 6.1**, so please consult the
:std:doc:`deprecations` section in the docs for directions on how to update existing code.
In the pytest ``6.0.X`` series, it is possible to change the errors back into warnings as a
stopgap measure by adding this to your ``pytest.ini`` file:
.. code-block:: ini
[pytest]
filterwarnings =
ignore::pytest.PytestDeprecationWarning
But this will stop working when pytest ``6.1`` is released.
**If you have concerns** about the removal of a specific feature, please add a
comment to :issue:`5584`.
- :issue:`7472`: The ``exec_()`` and ``is_true()`` methods of ``_pytest._code.Frame`` have been removed.
Features
--------
- :issue:`7464`: Added support for :envvar:`NO_COLOR` and :envvar:`FORCE_COLOR` environment variables to control colored output.
Improvements
------------
- :issue:`7467`: ``--log-file`` CLI option and ``log_file`` ini marker now create subdirectories if needed.
- :issue:`7489`: The :func:`pytest.raises` function has a clearer error message when ``match`` equals the obtained string but is not a regex match. In this case it is suggested to escape the regex.
Bug Fixes
---------
- :issue:`7392`: Fix the reported location of tests skipped with ``pytest.mark.skip`` when ``--runxfail`` is used.
- :issue:`7491`: :fixture:`tmpdir` and :fixture:`tmp_path` no longer raise an error if the lock to check for
stale temporary directories is not accessible.
- :issue:`7517`: Preserve line endings when captured via ``capfd``.
- :issue:`7534`: Restored the previous formatting of ``TracebackEntry.__str__`` which was changed by accident.
Improved Documentation
----------------------
- :issue:`7422`: Clarified when the ``usefixtures`` mark can apply fixtures to test.
- :issue:`7441`: Add a note about ``-q`` option used in getting started guide.
Trivial/Internal Changes
------------------------
- :issue:`7389`: Fixture scope ``package`` is no longer considered experimental.
```
### 6.0.0rc1
```
============================
Breaking Changes
----------------
- :issue:`1316`: ``TestReport.longrepr`` is now always an instance of ``ReprExceptionInfo``. Previously it was a ``str`` when a test failed with ``pytest.fail(..., pytrace=False)``.
- :issue:`5965`: symlinks are no longer resolved during collection and matching `conftest.py` files with test file paths.
Resolving symlinks for the current directory and during collection was introduced as a bugfix in 3.9.0, but it actually is a new feature which had unfortunate consequences in Windows and surprising results in other platforms.
The team decided to step back on resolving symlinks at all, planning to review this in the future with a more solid solution (see discussion in
:pull:`6523` for details).
This might break test suites which made use of this feature; the fix is to create a symlink
for the entire test tree, and not only to partial files/tress as it was possible previously.
- :issue:`6505`: ``Testdir.run().parseoutcomes()`` now always returns the parsed nouns in plural form.
Originally ``parseoutcomes()`` would always returns the nouns in plural form, but a change
meant to improve the terminal summary by using singular form single items (``1 warning`` or ``1 error``)
caused an unintended regression by changing the keys returned by ``parseoutcomes()``.
Now the API guarantees to always return the plural form, so calls like this:
.. code-block:: python
result = testdir.runpytest()
result.assert_outcomes(error=1)
Need to be changed to:
.. code-block:: python
result = testdir.runpytest()
result.assert_outcomes(errors=1)
- :issue:`6903`: The ``os.dup()`` function is now assumed to exist. We are not aware of any
supported Python 3 implementations which do not provide it.
- :issue:`7040`: ``-k`` no longer matches against the names of the directories outside the test session root.
Also, ``pytest.Package.name`` is now just the name of the directory containing the package's
``__init__.py`` file, instead of the full path. This is consistent with how the other nodes
are named, and also one of the reasons why ``-k`` would match against any directory containing
the test suite.
- :issue:`7122`: Expressions given to the ``-m`` and ``-k`` options are no longer evaluated using Python's :func:`eval`.
The format supports ``or``, ``and``, ``not``, parenthesis and general identifiers to match against.
Python constants, keywords or other operators are no longer evaluated differently.
- :issue:`7135`: Pytest now uses its own ``TerminalWriter`` class instead of using the one from the ``py`` library.
Plugins generally access this class through ``TerminalReporter.writer``, ``TerminalReporter.write()``
(and similar methods), or ``_pytest.config.create_terminal_writer()``.
The following breaking changes were made:
- Output (``write()`` method and others) no longer flush implicitly; the flushing behavior
of the underlying file is respected. To flush explicitly (for example, if you
want output to be shown before an end-of-line is printed), use ``write(flush=True)`` or
``terminal_writer.flush()``.
- Explicit Windows console support was removed, delegated to the colorama library.
- Support for writing ``bytes`` was removed.
- The ``reline`` method and ``chars_on_current_line`` property were removed.
- The ``stringio`` and ``encoding`` arguments was removed.
- Support for passing a callable instead of a file was removed.
- :issue:`7224`: The `item.catch_log_handler` and `item.catch_log_handlers` attributes, set by the
logging plugin and never meant to be public, are no longer available.
The deprecated ``--no-print-logs`` option and ``log_print`` ini option are removed. Use ``--show-capture`` instead.
- :issue:`7226`: Removed the unused ``args`` parameter from ``pytest.Function.__init__``.
- :issue:`7418`: Removed the `pytest_doctest_prepare_content` hook specification. This hook
hasn't been triggered by pytest for at least 10 years.
- :issue:`7438`: Some changes were made to the internal ``_pytest._code.source``, listed here
for the benefit of plugin authors who may be using it:
- The ``deindent`` argument to ``Source()`` has been removed, now it is always true.
- Support for zero or multiple arguments to ``Source()`` has been removed.
- Support for comparing ``Source`` with an ``str`` has been removed.
- The methods ``Source.isparseable()`` and ``Source.putaround()`` have been removed.
- The method ``Source.compile()`` and function ``_pytest._code.compile()`` have
been removed; use plain ``compile()`` instead.
- The function ``_pytest._code.source.getsource()`` has been removed; use
``Source()`` directly instead.
Deprecations
------------
- :issue:`7210`: The special ``-k '-expr'`` syntax to ``-k`` is deprecated. Use ``-k 'not expr'``
instead.
The special ``-k 'expr:'`` syntax to ``-k`` is deprecated. Please open an issue
if you use this and want a replacement.
- :issue:`4049`: ``pytest_warning_captured`` is deprecated in favor of the ``pytest_warning_recorded`` hook.
Features
--------
- :issue:`1556`: pytest now supports ``pyproject.toml`` files for configuration.
The configuration options is similar to the one available in other formats, but must be defined
in a ``[tool.pytest.ini_options]`` table to be picked up by pytest:
.. code-block:: toml
pyproject.toml
[tool.pytest.ini_options]
minversion = "6.0"
addopts = "-ra -q"
testpaths = [
"tests",
"integration",
]
More information can be found :ref:`in the docs <config file formats>`.
- :issue:`3342`: pytest now includes inline type annotations and exposes them to user programs.
Most of the user-facing API is covered, as well as internal code.
If you are running a type checker such as mypy on your tests, you may start
noticing type errors indicating incorrect usage. If you run into an error that
you believe to be incorrect, please let us know in an issue.
The types were developed against mypy version 0.780. Versions before 0.750
are known not to work. We recommend using the latest version. Other type
checkers may work as well, but they are not officially verified to work by
pytest yet.
- :issue:`4049`: Introduced a new hook named `pytest_warning_recorded` to convey information about warnings captured by the internal `pytest` warnings plugin.
This hook is meant to replace `pytest_warning_captured`, which is deprecated and will be removed in a future release.
- :issue:`6471`: New command-line flags:
* `--no-header`: disables the initial header, including platform, version, and plugins.
* `--no-summary`: disables the final test summary, including warnings.
- :issue:`6856`: A warning is now shown when an unknown key is read from a config INI file.
The `--strict-config` flag has been added to treat these warnings as errors.
- :issue:`6906`: Added `--code-highlight` command line option to enable/disable code highlighting in terminal output.
- :issue:`7245`: New ``--import-mode=importlib`` option that uses :mod:`importlib` to import test modules.
Traditionally pytest used ``__import__`` while changing ``sys.path`` to import test modules (which
also changes ``sys.modules`` as a side-effect), which works but has a number of drawbacks, like requiring test modules
that don't live in packages to have unique names (as they need to reside under a unique name in ``sys.modules``).
``--import-mode=importlib`` uses more fine grained import mechanisms from ``importlib`` which don't
require pytest to change ``sys.path`` or ``sys.modules`` at all, eliminating much of the drawbacks
of the previous mode.
We intend to make ``--import-mode=importlib`` the default in future versions, so users are encouraged
to try the new mode and provide feedback (both positive or negative) in issue :issue:`7245`.
You can read more about this option in :std:ref:`the documentation <import-modes>`.
- :issue:`7305`:
This PR updates pytest from 4.6.3 to 7.1.0.
Changelog
### 7.1.0 ``` ========================= Breaking Changes ---------------- - `8838 <https://github.com/pytest-dev/pytest/issues/8838>`_: As per our policy, the following features have been deprecated in the 6.X series and are now removed: * ``pytest._fillfuncargs`` function. * ``pytest_warning_captured`` hook - use ``pytest_warning_recorded`` instead. * ``-k -foobar`` syntax - use ``-k 'not foobar'`` instead. * ``-k foobar:`` syntax. * ``pytest.collect`` module - import from ``pytest`` directly. For more information consult `Deprecations and Removals <https://docs.pytest.org/en/latest/deprecations.html>`__ in the docs. - `9437 <https://github.com/pytest-dev/pytest/issues/9437>`_: Dropped support for Python 3.6, which reached `end-of-life <https://devguide.python.org/#status-of-python-branches>`__ at 2021-12-23. Improvements ------------ - `5192 <https://github.com/pytest-dev/pytest/issues/5192>`_: Fixed test output for some data types where ``-v`` would show less information. Also, when showing diffs for sequences, ``-q`` would produce full diffs instead of the expected diff. - `9362 <https://github.com/pytest-dev/pytest/issues/9362>`_: pytest now avoids specialized assert formatting when it is detected that the default ``__eq__`` is overridden in ``attrs`` or ``dataclasses``. - `9536 <https://github.com/pytest-dev/pytest/issues/9536>`_: When ``-vv`` is given on command line, show skipping and xfail reasons in full instead of truncating them to fit the terminal width. - `9644 <https://github.com/pytest-dev/pytest/issues/9644>`_: More information about the location of resources that led Python to raise :class:`ResourceWarning` can now be obtained by enabling :mod:`tracemalloc`. See :ref:`resource-warnings` for more information. - `9678 <https://github.com/pytest-dev/pytest/issues/9678>`_: More types are now accepted in the ``ids`` argument to ``pytest.mark.parametrize``. Previously only `str`, `float`, `int` and `bool` were accepted; now `bytes`, `complex`, `re.Pattern`, `Enum` and anything with a `__name__` are also accepted. - `9692 <https://github.com/pytest-dev/pytest/issues/9692>`_: :func:`pytest.approx` now raises a :class:`TypeError` when given an unordered sequence (such as :class:`set`). Note that this implies that custom classes which only implement ``__iter__`` and ``__len__`` are no longer supported as they don't guarantee order. Bug Fixes --------- - `8242 <https://github.com/pytest-dev/pytest/issues/8242>`_: The deprecation of raising :class:`unittest.SkipTest` to skip collection of tests during the pytest collection phase is reverted - this is now a supported feature again. - `9493 <https://github.com/pytest-dev/pytest/issues/9493>`_: Symbolic link components are no longer resolved in conftest paths. This means that if a conftest appears twice in collection tree, using symlinks, it will be executed twice. For example, given tests/real/conftest.py tests/real/test_it.py tests/link -> tests/real running ``pytest tests`` now imports the conftest twice, once as ``tests/real/conftest.py`` and once as ``tests/link/conftest.py``. This is a fix to match a similar change made to test collection itself in pytest 6.0 (see :pull:`6523` for details). - `9626 <https://github.com/pytest-dev/pytest/issues/9626>`_: Fixed count of selected tests on terminal collection summary when there were errors or skipped modules. If there were errors or skipped modules on collection, pytest would mistakenly subtract those from the selected count. - `9645 <https://github.com/pytest-dev/pytest/issues/9645>`_: Fixed regression where ``--import-mode=importlib`` used together with :envvar:`PYTHONPATH` or :confval:`pythonpath` would cause import errors in test suites. - `9708 <https://github.com/pytest-dev/pytest/issues/9708>`_: :fixture:`pytester` now requests a :fixture:`monkeypatch` fixture instead of creating one internally. This solves some issues with tests that involve pytest environment variables. - `9730 <https://github.com/pytest-dev/pytest/issues/9730>`_: Malformed ``pyproject.toml`` files now produce a clearer error message. ``` ### 7.0.1 ``` ========================= Bug Fixes --------- - `9608 <https://github.com/pytest-dev/pytest/issues/9608>`_: Fix invalid importing of ``importlib.readers`` in Python 3.9. - `9610 <https://github.com/pytest-dev/pytest/issues/9610>`_: Restore `UnitTestFunction.obj` to return unbound rather than bound method. Fixes a crash during a failed teardown in unittest TestCases with non-default `__init__`. Regressed in pytest 7.0.0. - `9636 <https://github.com/pytest-dev/pytest/issues/9636>`_: The ``pythonpath`` plugin was renamed to ``python_path``. This avoids a conflict with the ``pytest-pythonpath`` plugin. - `9642 <https://github.com/pytest-dev/pytest/issues/9642>`_: Fix running tests by id with ``::`` in the parametrize portion. - `9643 <https://github.com/pytest-dev/pytest/issues/9643>`_: Delay issuing a :class:`~pytest.PytestWarning` about diamond inheritance involving :class:`~pytest.Item` and :class:`~pytest.Collector` so it can be filtered using :ref:`standard warning filters <warnings>`. ``` ### 7.0.0 ``` ========================= (**Please see the full set of changes for this release also in the 7.0.0rc1 notes below**) Deprecations ------------ - `9488 <https://github.com/pytest-dev/pytest/issues/9488>`_: If custom subclasses of nodes like :class:`pytest.Item` override the ``__init__`` method, they should take ``**kwargs``. See :ref:`uncooperative-constructors-deprecated` for details. Note that a deprection warning is only emitted when there is a conflict in the arguments pytest expected to pass. This deprecation was already part of pytest 7.0.0rc1 but wasn't documented. Bug Fixes --------- - `9355 <https://github.com/pytest-dev/pytest/issues/9355>`_: Fixed error message prints function decorators when using assert in Python 3.8 and above. - `9396 <https://github.com/pytest-dev/pytest/issues/9396>`_: Ensure :attr:`pytest.Config.inifile` is available during the :func:`pytest_cmdline_main <_pytest.hookspec.pytest_cmdline_main>` hook (regression during ``7.0.0rc1``). Improved Documentation ---------------------- - `9404 <https://github.com/pytest-dev/pytest/issues/9404>`_: Added extra documentation on alternatives to common misuses of `pytest.warns(None)` ahead of its deprecation. - `9505 <https://github.com/pytest-dev/pytest/issues/9505>`_: Clarify where the configuration files are located. To avoid confusions documentation mentions that configuration file is located in the root of the repository. Trivial/Internal Changes ------------------------ - `9521 <https://github.com/pytest-dev/pytest/issues/9521>`_: Add test coverage to assertion rewrite path. ``` ### 7.0.0rc1 ``` ============================ Breaking Changes ---------------- - `7259 <https://github.com/pytest-dev/pytest/issues/7259>`_: The :ref:`Node.reportinfo() <non-python tests>` function first return value type has been expanded from `py.path.local | str` to `os.PathLike[str] | str`. Most plugins which refer to `reportinfo()` only define it as part of a custom :class:`pytest.Item` implementation. Since `py.path.local` is a `os.PathLike[str]`, these plugins are unaffacted. Plugins and users which call `reportinfo()`, use the first return value and interact with it as a `py.path.local`, would need to adjust by calling `py.path.local(fspath)`. Although preferably, avoid the legacy `py.path.local` and use `pathlib.Path`, or use `item.location` or `item.path`, instead. Note: pytest was not able to provide a deprecation period for this change. - `8246 <https://github.com/pytest-dev/pytest/issues/8246>`_: ``--version`` now writes version information to ``stdout`` rather than ``stderr``. - `8733 <https://github.com/pytest-dev/pytest/issues/8733>`_: Drop a workaround for `pyreadline <https://github.com/pyreadline/pyreadline>`__ that made it work with ``--pdb``. The workaround was introduced in `1281 <https://github.com/pytest-dev/pytest/pull/1281>`__ in 2015, however since then `pyreadline seems to have gone unmaintained <https://github.com/pyreadline/pyreadline/issues/58>`__, is `generating warnings <https://github.com/pytest-dev/pytest/issues/8847>`__, and will stop working on Python 3.10. - `9061 <https://github.com/pytest-dev/pytest/issues/9061>`_: Using :func:`pytest.approx` in a boolean context now raises an error hinting at the proper usage. It is apparently common for users to mistakenly use ``pytest.approx`` like this: .. code-block:: python assert pytest.approx(actual, expected) While the correct usage is: .. code-block:: python assert actual == pytest.approx(expected) The new error message helps catch those mistakes. - `9277 <https://github.com/pytest-dev/pytest/issues/9277>`_: The ``pytest.Instance`` collector type has been removed. Importing ``pytest.Instance`` or ``_pytest.python.Instance`` returns a dummy type and emits a deprecation warning. See :ref:`instance-collector-deprecation` for details. - `9308 <https://github.com/pytest-dev/pytest/issues/9308>`_: **PytestRemovedIn7Warning deprecation warnings are now errors by default.** Following our plan to remove deprecated features with as little disruption as possible, all warnings of type ``PytestRemovedIn7Warning`` now generate errors instead of warning messages by default. **The affected features will be effectively removed in pytest 7.1**, so please consult the :ref:`deprecations` section in the docs for directions on how to update existing code. In the pytest ``7.0.X`` series, it is possible to change the errors back into warnings as a stopgap measure by adding this to your ``pytest.ini`` file: .. code-block:: ini [pytest] filterwarnings = ignore::pytest.PytestRemovedIn7Warning But this will stop working when pytest ``7.1`` is released. **If you have concerns** about the removal of a specific feature, please add a comment to :issue:`9308`. Deprecations ------------ - `7259 <https://github.com/pytest-dev/pytest/issues/7259>`_: ``py.path.local`` arguments for hooks have been deprecated. See :ref:`the deprecation note <legacy-path-hooks-deprecated>` for full details. ``py.path.local`` arguments to Node constructors have been deprecated. See :ref:`the deprecation note <node-ctor-fspath-deprecation>` for full details. .. note:: The name of the :class:`~_pytest.nodes.Node` arguments and attributes (the new attribute being ``path``) is **the opposite** of the situation for hooks (the old argument being ``path``). This is an unfortunate artifact due to historical reasons, which should be resolved in future versions as we slowly get rid of the :pypi:`py` dependency (see :issue:`9283` for a longer discussion). - `7469 <https://github.com/pytest-dev/pytest/issues/7469>`_: Directly constructing the following classes is now deprecated: - ``_pytest.mark.structures.Mark`` - ``_pytest.mark.structures.MarkDecorator`` - ``_pytest.mark.structures.MarkGenerator`` - ``_pytest.python.Metafunc`` - ``_pytest.runner.CallInfo`` - ``_pytest._code.ExceptionInfo`` - ``_pytest.config.argparsing.Parser`` - ``_pytest.config.argparsing.OptionGroup`` - ``_pytest.pytester.HookRecorder`` These constructors have always been considered private, but now issue a deprecation warning, which may become a hard error in pytest 8. - `8242 <https://github.com/pytest-dev/pytest/issues/8242>`_: Raising :class:`unittest.SkipTest` to skip collection of tests during the pytest collection phase is deprecated. Use :func:`pytest.skip` instead. Note: This deprecation only relates to using :class:`unittest.SkipTest` during test collection. You are probably not doing that. Ordinary usage of :class:`unittest.SkipTest` / :meth:`unittest.TestCase.skipTest` / :func:`unittest.skip` in unittest test cases is fully supported. .. note:: This deprecation has been reverted in pytest 7.1.0. - `8315 <https://github.com/pytest-dev/pytest/issues/8315>`_: Several behaviors of :meth:`Parser.addoption <pytest.Parser.addoption>` are now scheduled for removal in pytest 8 (deprecated since pytest 2.4.0): - ``parser.addoption(..., help=".. %default ..")`` - use ``%(default)s`` instead. - ``parser.addoption(..., type="int/string/float/complex")`` - use ``type=int`` etc. instead. - `8447 <https://github.com/pytest-dev/pytest/issues/8447>`_: Defining a custom pytest node type which is both an :class:`pytest.Item <Item>` and a :class:`pytest.Collector <Collector>` (e.g. :class:`pytest.File <File>`) now issues a warning. It was never sanely supported and triggers hard to debug errors. See :ref:`the deprecation note <diamond-inheritance-deprecated>` for full details. - `8592 <https://github.com/pytest-dev/pytest/issues/8592>`_: :hook:`pytest_cmdline_preparse` has been officially deprecated. It will be removed in a future release. Use :hook:`pytest_load_initial_conftests` instead. See :ref:`the deprecation note <cmdline-preparse-deprecated>` for full details. - `8645 <https://github.com/pytest-dev/pytest/issues/8645>`_: :func:`pytest.warns(None) <pytest.warns>` is now deprecated because many people used it to mean "this code does not emit warnings", but it actually had the effect of checking that the code emits at least one warning of any type - like ``pytest.warns()`` or ``pytest.warns(Warning)``. - `8948 <https://github.com/pytest-dev/pytest/issues/8948>`_: :func:`pytest.skip(msg=...) <pytest.skip>`, :func:`pytest.fail(msg=...) <pytest.fail>` and :func:`pytest.exit(msg=...) <pytest.exit>` signatures now accept a ``reason`` argument instead of ``msg``. Using ``msg`` still works, but is deprecated and will be removed in a future release. This was changed for consistency with :func:`pytest.mark.skip <pytest.mark.skip>` and :func:`pytest.mark.xfail <pytest.mark.xfail>` which both accept ``reason`` as an argument. - `8174 <https://github.com/pytest-dev/pytest/issues/8174>`_: The following changes have been made to types reachable through :attr:`pytest.ExceptionInfo.traceback`: - The ``path`` property of ``_pytest.code.Code`` returns ``Path`` instead of ``py.path.local``. - The ``path`` property of ``_pytest.code.TracebackEntry`` returns ``Path`` instead of ``py.path.local``. There was no deprecation period for this change (sorry!). Features -------- - `5196 <https://github.com/pytest-dev/pytest/issues/5196>`_: Tests are now ordered by definition order in more cases. In a class hierarchy, tests from base classes are now consistently ordered before tests defined on their subclasses (reverse MRO order). - `7132 <https://github.com/pytest-dev/pytest/issues/7132>`_: Added two environment variables :envvar:`PYTEST_THEME` and :envvar:`PYTEST_THEME_MODE` to let the users customize the pygments theme used. - `7259 <https://github.com/pytest-dev/pytest/issues/7259>`_: Added :meth:`cache.mkdir() <pytest.Cache.mkdir>`, which is similar to the existing :meth:`cache.makedir() <pytest.Cache.makedir>`, but returns a :class:`pathlib.Path` instead of a legacy ``py.path.local``. Added a ``paths`` type to :meth:`parser.addini() <pytest.Parser.addini>`, as in ``parser.addini("mypaths", "my paths", type="paths")``, which is similar to the existing ``pathlist``, but returns a list of :class:`pathlib.Path` instead of legacy ``py.path.local``. - `7469 <https://github.com/pytest-dev/pytest/issues/7469>`_: The types of objects used in pytest's API are now exported so they may be used in type annotations. The newly-exported types are: - ``pytest.Config`` for :class:`Config <pytest.Config>`. - ``pytest.Mark`` for :class:`marks <pytest.Mark>`. - ``pytest.MarkDecorator`` for :class:`mark decorators <pytest.MarkDecorator>`. - ``pytest.MarkGenerator`` for the :class:`pytest.mark <pytest.MarkGenerator>` singleton. - ``pytest.Metafunc`` for the :class:`metafunc <pytest.MarkGenerator>` argument to the :hook:`pytest_generate_tests` hook. - ``pytest.CallInfo`` for the :class:`CallInfo <pytest.CallInfo>` type passed to various hooks. - ``pytest.PytestPluginManager`` for :class:`PytestPluginManager <pytest.PytestPluginManager>`. - ``pytest.ExceptionInfo`` for the :class:`ExceptionInfo <pytest.ExceptionInfo>` type returned from :func:`pytest.raises` and passed to various hooks. - ``pytest.Parser`` for the :class:`Parser <pytest.Parser>` type passed to the :hook:`pytest_addoption` hook. - ``pytest.OptionGroup`` for the :class:`OptionGroup <pytest.OptionGroup>` type returned from the :func:`parser.addgroup <pytest.Parser.getgroup>` method. - ``pytest.HookRecorder`` for the :class:`HookRecorder <pytest.HookRecorder>` type returned from :class:`~pytest.Pytester`. - ``pytest.RecordedHookCall`` for the :class:`RecordedHookCall <pytest.HookRecorder>` type returned from :class:`~pytest.HookRecorder`. - ``pytest.RunResult`` for the :class:`RunResult <pytest.RunResult>` type returned from :class:`~pytest.Pytester`. - ``pytest.LineMatcher`` for the :class:`LineMatcher <pytest.RunResult>` type used in :class:`~pytest.RunResult` and others. - ``pytest.TestReport`` for the :class:`TestReport <pytest.TestReport>` type used in various hooks. - ``pytest.CollectReport`` for the :class:`CollectReport <pytest.CollectReport>` type used in various hooks. Constructing most of them directly is not supported; they are only meant for use in type annotations. Doing so will emit a deprecation warning, and may become a hard-error in pytest 8.0. Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy. - `7856 <https://github.com/pytest-dev/pytest/issues/7856>`_: :ref:`--import-mode=importlib <import-modes>` now works with features that depend on modules being on :py:data:`sys.modules`, such as :mod:`pickle` and :mod:`dataclasses`. - `8144 <https://github.com/pytest-dev/pytest/issues/8144>`_: The following hooks now receive an additional ``pathlib.Path`` argument, equivalent to an existing ``py.path.local`` argument: - :hook:`pytest_ignore_collect` - The ``collection_path`` parameter (equivalent to existing ``path`` parameter). - :hook:`pytest_collect_file` - The ``file_path`` parameter (equivalent to existing ``path`` parameter). - :hook:`pytest_pycollect_makemodule` - The ``module_path`` parameter (equivalent to existing ``path`` parameter). - :hook:`pytest_report_header` - The ``start_path`` parameter (equivalent to existing ``startdir`` parameter). - :hook:`pytest_report_collectionfinish` - The ``start_path`` parameter (equivalent to existing ``startdir`` parameter). .. note:: The name of the :class:`~_pytest.nodes.Node` arguments and attributes (the new attribute being ``path``) is **the opposite** of the situation for hooks (the old argument being ``path``). This is an unfortunate artifact due to historical reasons, which should be resolved in future versions as we slowly get rid of the :pypi:`py` dependency (see :issue:`9283` for a longer discussion). - `8251 <https://github.com/pytest-dev/pytest/issues/8251>`_: Implement ``Node.path`` as a ``pathlib.Path``. Both the old ``fspath`` and this new attribute gets set no matter whether ``path`` or ``fspath`` (deprecated) is passed to the constructor. It is a replacement for the ``fspath`` attribute (which represents the same path as ``py.path.local``). While ``fspath`` is not deprecated yet due to the ongoing migration of methods like :meth:`~_pytest.Item.reportinfo`, we expect to deprecate it in a future release. .. note:: The name of the :class:`~_pytest.nodes.Node` arguments and attributes (the new attribute being ``path``) is **the opposite** of the situation for hooks (the old argument being ``path``). This is an unfortunate artifact due to historical reasons, which should be resolved in future versions as we slowly get rid of the :pypi:`py` dependency (see :issue:`9283` for a longer discussion). - `8421 <https://github.com/pytest-dev/pytest/issues/8421>`_: :func:`pytest.approx` now works on :class:`~decimal.Decimal` within mappings/dicts and sequences/lists. - `8606 <https://github.com/pytest-dev/pytest/issues/8606>`_: pytest invocations with ``--fixtures-per-test`` and ``--fixtures`` have been enriched with: - Fixture location path printed with the fixture name. - First section of the fixture's docstring printed under the fixture name. - Whole of fixture's docstring printed under the fixture name using ``--verbose`` option. - `8761 <https://github.com/pytest-dev/pytest/issues/8761>`_: New :ref:`version-tuple` attribute, which makes it simpler for users to do something depending on the pytest version (such as declaring hooks which are introduced in later versions). - `8789 <https://github.com/pytest-dev/pytest/issues/8789>`_: Switch TOML parser from ``toml`` to ``tomli`` for TOML v1.0.0 support in ``pyproject.toml``. - `8920 <https://github.com/pytest-dev/pytest/issues/8920>`_: Added :class:`pytest.Stash`, a facility for plugins to store their data on :class:`~pytest.Config` and :class:`~_pytest.nodes.Node`\s in a type-safe and conflict-free manner. See :ref:`plugin-stash` for details. - `8953 <https://github.com/pytest-dev/pytest/issues/8953>`_: :class:`RunResult <_pytest.pytester.RunResult>` method :meth:`assert_outcomes <_pytest.pytester.RunResult.assert_outcomes>` now accepts a ``warnings`` argument to assert the total number of warnings captured. - `8954 <https://github.com/pytest-dev/pytest/issues/8954>`_: ``--debug`` flag now accepts a :class:`str` file to route debug logs into, remains defaulted to `pytestdebug.log`. - `9023 <https://github.com/pytest-dev/pytest/issues/9023>`_: Full diffs are now always shown for equality assertions of iterables when `CI` or ``BUILD_NUMBER`` is found in the environment, even when ``-v`` isn't used. - `9113 <https://github.com/pytest-dev/pytest/issues/9113>`_: :class:`RunResult <_pytest.pytester.RunResult>` method :meth:`assert_outcomes <_pytest.pytester.RunResult.assert_outcomes>` now accepts a ``deselected`` argument to assert the total number of deselected tests. - `9114 <https://github.com/pytest-dev/pytest/issues/9114>`_: Added :confval:`pythonpath` setting that adds listed paths to :data:`sys.path` for the duration of the test session. If you currently use the pytest-pythonpath or pytest-srcpaths plugins, you should be able to replace them with built-in `pythonpath` setting. Improvements ------------ - `7480 <https://github.com/pytest-dev/pytest/issues/7480>`_: A deprecation scheduled to be removed in a major version X (e.g. pytest 7, 8, 9, ...) now uses warning category `PytestRemovedInXWarning`, a subclass of :class:`~pytest.PytestDeprecationWarning`, instead of :class:`PytestDeprecationWarning` directly. See :ref:`backwards-compatibility` for more details. - `7864 <https://github.com/pytest-dev/pytest/issues/7864>`_: Improved error messages when parsing warning filters. Previously pytest would show an internal traceback, which besides being ugly sometimes would hide the cause of the problem (for example an ``ImportError`` while importing a specific warning type). - `8335 <https://github.com/pytest-dev/pytest/issues/8335>`_: Improved :func:`pytest.approx` assertion messages for sequences of numbers. The assertion messages now dumps a table with the index and the error of each diff. Example:: > assert [1, 2, 3, 4] == pytest.approx([1, 3, 3, 5]) E assert comparison failed for 2 values: E Index | Obtained | Expected E 1 | 2 | 3 +- 3.0e-06 E 3 | 4 | 5 +- 5.0e-06 - `8403 <https://github.com/pytest-dev/pytest/issues/8403>`_: By default, pytest will truncate long strings in assert errors so they don't clutter the output too much, currently at ``240`` characters by default. However, in some cases the longer output helps, or is even crucial, to diagnose a failure. Using ``-v`` will now increase the truncation threshold to ``2400`` characters, and ``-vv`` or higher will disable truncation entirely. - `8509 <https://github.com/pytest-dev/pytest/issues/8509>`_: Fixed issue where :meth:`unittest.TestCase.setUpClass` is not called when a test has `/` in its name since pytest 6.2.0. This refers to the path part in pytest node IDs, e.g. ``TestClass::test_it`` in the node ID ``tests/test_file.py::TestClass::test_it``. Now, instead of assuming that the test name does not contain ``/``, it is assumed that test path does not contain ``::``. We plan to hopefully make both of these work in the future. - `8803 <https://github.com/pytest-dev/pytest/issues/8803>`_: It is now possible to add colors to custom log levels on cli log. By using :func:`add_color_level <_pytest.logging.add_color_level>` from a ``pytest_configure`` hook, colors can be added:: logging_plugin = config.pluginmanager.get_plugin('logging-plugin') logging_plugin.log_cli_handler.formatter.add_color_level(logging.INFO, 'cyan') logging_plugin.log_cli_handler.formatter.add_color_level(logging.SPAM, 'blue') See :ref:`log_colors` for more information. - `8822 <https://github.com/pytest-dev/pytest/issues/8822>`_: When showing fixture paths in `--fixtures` or `--fixtures-by-test`, fixtures coming from pytest itself now display an elided path, rather than the full path to the file in the `site-packages` directory. - `8898 <https://github.com/pytest-dev/pytest/issues/8898>`_: Complex numbers are now treated like floats and integers when generating parameterization IDs. - `9062 <https://github.com/pytest-dev/pytest/issues/9062>`_: ``--stepwise-skip`` now implicitly enables ``--stepwise`` and can be used on its own. - `9205 <https://github.com/pytest-dev/pytest/issues/9205>`_: :meth:`pytest.Cache.set` now preserves key order when saving dicts. Bug Fixes --------- - `7124 <https://github.com/pytest-dev/pytest/issues/7124>`_: Fixed an issue where ``__main__.py`` would raise an ``ImportError`` when ``--doctest-modules`` was provided. - `8061 <https://github.com/pytest-dev/pytest/issues/8061>`_: Fixed failing ``staticmethod`` test cases if they are inherited from a parent test class. - `8192 <https://github.com/pytest-dev/pytest/issues/8192>`_: ``testdir.makefile`` now silently accepts values which don't start with ``.`` to maintain backward compatibility with older pytest versions. ``pytester.makefile`` now issues a clearer error if the ``.`` is missing in the ``ext`` argument. - `8258 <https://github.com/pytest-dev/pytest/issues/8258>`_: Fixed issue where pytest's ``faulthandler`` support would not dump traceback on crashes if the :mod:`faulthandler` module was already enabled during pytest startup (using ``python -X dev -m pytest`` for example). - `8317 <https://github.com/pytest-dev/pytest/issues/8317>`_: Fixed an issue where illegal directory characters derived from ``getpass.getuser()`` raised an ``OSError``. - `8367 <https://github.com/pytest-dev/pytest/issues/8367>`_: Fix ``Class.from_parent`` so it forwards extra keyword arguments to the constructor. - `8377 <https://github.com/pytest-dev/pytest/issues/8377>`_: The test selection options ``pytest -k`` and ``pytest -m`` now support matching names containing forward slash (``/``) characters. - `8384 <https://github.com/pytest-dev/pytest/issues/8384>`_: The ``pytest.mark.skip`` decorator now correctly handles its arguments. When the ``reason`` argument is accidentally given both positional and as a keyword (e.g. because it was confused with ``skipif``), a ``TypeError`` now occurs. Before, such tests were silently skipped, and the positional argument ignored. Additionally, ``reason`` is now documented correctly as positional or keyword (rather than keyword-only). - `8394 <https://github.com/pytest-dev/pytest/issues/8394>`_: Use private names for internal fixtures that handle classic setup/teardown so that they don't show up with the default ``--fixtures`` invocation (but they still show up with ``--fixtures -v``). - `8456 <https://github.com/pytest-dev/pytest/issues/8456>`_: The :confval:`required_plugins` config option now works correctly when pre-releases of plugins are installed, rather than falsely claiming that those plugins aren't installed at all. - `8464 <https://github.com/pytest-dev/pytest/issues/8464>`_: ``-c <config file>`` now also properly defines ``rootdir`` as the directory that contains ``<config file>``. - `8503 <https://github.com/pytest-dev/pytest/issues/8503>`_: :meth:`pytest.MonkeyPatch.syspath_prepend` no longer fails when ``setuptools`` is not installed. It now only calls :func:`pkg_resources.fixup_namespace_packages` if ``pkg_resources`` was previously imported, because it is not needed otherwise. - `8548 <https://github.com/pytest-dev/pytest/issues/8548>`_: Introduce fix to handle precision width in ``log-cli-format`` in turn to fix output coloring for certain formats. - `8796 <https://github.com/pytest-dev/pytest/issues/8796>`_: Fixed internal error when skipping doctests. - `8983 <https://github.com/pytest-dev/pytest/issues/8983>`_: The test selection options ``pytest -k`` and ``pytest -m`` now support matching names containing backslash (`\\`) characters. Backslashes are treated literally, not as escape characters (the values being matched against are already escaped). - `8990 <https://github.com/pytest-dev/pytest/issues/8990>`_: Fix `pytest -vv` crashing with an internal exception `AttributeError: 'str' object has no attribute 'relative_to'` in some cases. - `9077 <https://github.com/pytest-dev/pytest/issues/9077>`_: Fixed confusing error message when ``request.fspath`` / ``request.path`` was accessed from a session-scoped fixture. - `9131 <https://github.com/pytest-dev/pytest/issues/9131>`_: Fixed the URL used by ``--pastebin`` to use `bpa.st <http://bpa.st>`__. - `9163 <https://github.com/pytest-dev/pytest/issues/9163>`_: The end line number and end column offset are now properly set for rewritten assert statements. - `9169 <https://github.com/pytest-dev/pytest/issues/9169>`_: Support for the ``files`` API from ``importlib.resources`` within rewritten files. - `9272 <https://github.com/pytest-dev/pytest/issues/9272>`_: The nose compatibility module-level fixtures `setup()` and `teardown()` are now only called once per module, instead of for each test function. They are now called even if object-level `setup`/`teardown` is defined. Improved Documentation ---------------------- - `4320 <https://github.com/pytest-dev/pytest/issues/4320>`_: Improved docs for `pytester.copy_example`. - `5105 <https://github.com/pytest-dev/pytest/issues/5105>`_: Add automatically generated :ref:`plugin-list`. The list is updated on a periodic schedule. - `8337 <https://github.com/pytest-dev/pytest/issues/8337>`_: Recommend `numpy.testing <https://numpy.org/doc/stable/reference/routines.testing.html>`__ module on :func:`pytest.approx` documentation. - `8655 <https://github.com/pytest-dev/pytest/issues/8655>`_: Help text for ``--pdbcls`` more accurately reflects the option's behavior. - `9210 <https://github.com/pytest-dev/pytest/issues/9210>`_: Remove incorrect docs about ``confcutdir`` being a configuration option: it can only be set through the ``--confcutdir`` command-line option. - `9242 <https://github.com/pytest-dev/pytest/issues/9242>`_: Upgrade readthedocs configuration to use a `newer Ubuntu version <https://blog.readthedocs.com/new-build-specification/>`__` with better unicode support for PDF docs. - `9341 <https://github.com/pytest-dev/pytest/issues/9341>`_: Various methods commonly used for :ref:`non-python tests` are now correctly documented in the reference docs. They were undocumented previously. Trivial/Internal Changes ------------------------ - `8133 <https://github.com/pytest-dev/pytest/issues/8133>`_: Migrate to ``setuptools_scm`` 6.x to use ``SETUPTOOLS_SCM_PRETEND_VERSION_FOR_PYTEST`` for more robust release tooling. - `8174 <https://github.com/pytest-dev/pytest/issues/8174>`_: The following changes have been made to internal pytest types/functions: - The ``_pytest.code.getfslineno()`` function returns ``Path`` instead of ``py.path.local``. - The ``_pytest.python.path_matches_patterns()`` function takes ``Path`` instead of ``py.path.local``. - The ``_pytest._code.Traceback.cut()`` function accepts any ``os.PathLike[str]``, not just ``py.path.local``. - `8248 <https://github.com/pytest-dev/pytest/issues/8248>`_: Internal Restructure: let ``python.PyObjMixin`` inherit from ``nodes.Node`` to carry over typing information. - `8432 <https://github.com/pytest-dev/pytest/issues/8432>`_: Improve error message when :func:`pytest.skip` is used at module level without passing `allow_module_level=True`. - `8818 <https://github.com/pytest-dev/pytest/issues/8818>`_: Ensure ``regendoc`` opts out of ``TOX_ENV`` cachedir selection to ensure independent example test runs. - `8913 <https://github.com/pytest-dev/pytest/issues/8913>`_: The private ``CallSpec2._arg2scopenum`` attribute has been removed after an internal refactoring. - `8967 <https://github.com/pytest-dev/pytest/issues/8967>`_: :hook:`pytest_assertion_pass` is no longer considered experimental and future changes to it will be considered more carefully. - `9202 <https://github.com/pytest-dev/pytest/issues/9202>`_: Add github action to upload coverage report to codecov instead of bash uploader. - `9225 <https://github.com/pytest-dev/pytest/issues/9225>`_: Changed the command used to create sdist and wheel artifacts: using the build package instead of setup.py. - `9351 <https://github.com/pytest-dev/pytest/issues/9351>`_: Correct minor typos in doc/en/example/special.rst. ``` ### 6.2.5 ``` ========================= Trivial/Internal Changes ------------------------ - :issue:`8494`: Python 3.10 is now supported. - :issue:`9040`: Enable compatibility with ``pluggy 1.0`` or later. ``` ### 6.2.4 ``` ========================= Bug Fixes --------- - :issue:`8539`: Fixed assertion rewriting on Python 3.10. ``` ### 6.2.3 ``` ========================= Bug Fixes --------- - :issue:`8414`: pytest used to create directories under ``/tmp`` with world-readable permissions. This means that any user in the system was able to read information written by tests in temporary directories (such as those created by the ``tmp_path``/``tmpdir`` fixture). Now the directories are created with private permissions. pytest used to silently use a pre-existing ``/tmp/pytest-of-<username>`` directory, even if owned by another user. This means another user could pre-create such a directory and gain control of another user's temporary directory. Now such a condition results in an error. ``` ### 6.2.2 ``` ========================= Bug Fixes --------- - :issue:`8152`: Fixed "(<Skipped instance>)" being shown as a skip reason in the verbose test summary line when the reason is empty. - :issue:`8249`: Fix the ``faulthandler`` plugin for occasions when running with ``twisted.logger`` and using ``pytest --capture=no``. ``` ### 6.2.1 ``` ========================= Bug Fixes --------- - :issue:`7678`: Fixed bug where ``ImportPathMismatchError`` would be raised for files compiled in the host and loaded later from an UNC mounted path (Windows). - :issue:`8132`: Fixed regression in ``approx``: in 6.2.0 ``approx`` no longer raises ``TypeError`` when dealing with non-numeric types, falling back to normal comparison. Before 6.2.0, array types like tf.DeviceArray fell through to the scalar case, and happened to compare correctly to a scalar if they had only one element. After 6.2.0, these types began failing, because they inherited neither from standard Python number hierarchy nor from ``numpy.ndarray``. ``approx`` now converts arguments to ``numpy.ndarray`` if they expose the array protocol and are not scalars. This treats array-like objects like numpy arrays, regardless of size. ``` ### 6.2.0 ``` ========================= Breaking Changes ---------------- - :issue:`7808`: pytest now supports python3.6+ only. Deprecations ------------ - :issue:`7469`: Directly constructing/calling the following classes/functions is now deprecated: - ``_pytest.cacheprovider.Cache`` - ``_pytest.cacheprovider.Cache.for_config()`` - ``_pytest.cacheprovider.Cache.clear_cache()`` - ``_pytest.cacheprovider.Cache.cache_dir_from_config()`` - ``_pytest.capture.CaptureFixture`` - ``_pytest.fixtures.FixtureRequest`` - ``_pytest.fixtures.SubRequest`` - ``_pytest.logging.LogCaptureFixture`` - ``_pytest.pytester.Pytester`` - ``_pytest.pytester.Testdir`` - ``_pytest.recwarn.WarningsRecorder`` - ``_pytest.recwarn.WarningsChecker`` - ``_pytest.tmpdir.TempPathFactory`` - ``_pytest.tmpdir.TempdirFactory`` These have always been considered private, but now issue a deprecation warning, which may become a hard error in pytest 8.0.0. - :issue:`7530`: The ``--strict`` command-line option has been deprecated, use ``--strict-markers`` instead. We have plans to maybe in the future to reintroduce ``--strict`` and make it an encompassing flag for all strictness related options (``--strict-markers`` and ``--strict-config`` at the moment, more might be introduced in the future). - :issue:`7988`: The ``pytest.yield_fixture`` decorator/function is now deprecated. Use :func:`pytest.fixture` instead. ``yield_fixture`` has been an alias for ``fixture`` for a very long time, so can be search/replaced safely. Features -------- - :issue:`5299`: pytest now warns about unraisable exceptions and unhandled thread exceptions that occur in tests on Python>=3.8. See :ref:`unraisable` for more information. - :issue:`7425`: New :fixture:`pytester` fixture, which is identical to :fixture:`testdir` but its methods return :class:`pathlib.Path` when appropriate instead of ``py.path.local``. This is part of the movement to use :class:`pathlib.Path` objects internally, in order to remove the dependency to ``py`` in the future. Internally, the old :class:`Testdir <_pytest.pytester.Testdir>` is now a thin wrapper around :class:`Pytester <_pytest.pytester.Pytester>`, preserving the old interface. - :issue:`7695`: A new hook was added, `pytest_markeval_namespace` which should return a dictionary. This dictionary will be used to augment the "global" variables available to evaluate skipif/xfail/xpass markers. Pseudo example ``conftest.py``: .. code-block:: python def pytest_markeval_namespace(): return {"color": "red"} ``test_func.py``: .. code-block:: python pytest.mark.skipif("color == 'blue'", reason="Color is not red") def test_func(): assert False - :issue:`8006`: It is now possible to construct a :class:`~pytest.MonkeyPatch` object directly as ``pytest.MonkeyPatch()``, in cases when the :fixture:`monkeypatch` fixture cannot be used. Previously some users imported it from the private `_pytest.monkeypatch.MonkeyPatch` namespace. Additionally, :meth:`MonkeyPatch.context <pytest.MonkeyPatch.context>` is now a classmethod, and can be used as ``with MonkeyPatch.context() as mp: ...``. This is the recommended way to use ``MonkeyPatch`` directly, since unlike the ``monkeypatch`` fixture, an instance created directly is not ``undo()``-ed automatically. Improvements ------------ - :issue:`1265`: Added an ``__str__`` implementation to the :class:`~pytest.pytester.LineMatcher` class which is returned from ``pytester.run_pytest().stdout`` and similar. It returns the entire output, like the existing ``str()`` method. - :issue:`2044`: Verbose mode now shows the reason that a test was skipped in the test's terminal line after the "SKIPPED", "XFAIL" or "XPASS". - :issue:`7469` The types of builtin pytest fixtures are now exported so they may be used in type annotations of test functions. The newly-exported types are: - ``pytest.FixtureRequest`` for the :fixture:`request` fixture. - ``pytest.Cache`` for the :fixture:`cache` fixture. - ``pytest.CaptureFixture[str]`` for the :fixture:`capfd` and :fixture:`capsys` fixtures. - ``pytest.CaptureFixture[bytes]`` for the :fixture:`capfdbinary` and :fixture:`capsysbinary` fixtures. - ``pytest.LogCaptureFixture`` for the :fixture:`caplog` fixture. - ``pytest.Pytester`` for the :fixture:`pytester` fixture. - ``pytest.Testdir`` for the :fixture:`testdir` fixture. - ``pytest.TempdirFactory`` for the :fixture:`tmpdir_factory` fixture. - ``pytest.TempPathFactory`` for the :fixture:`tmp_path_factory` fixture. - ``pytest.MonkeyPatch`` for the :fixture:`monkeypatch` fixture. - ``pytest.WarningsRecorder`` for the :fixture:`recwarn` fixture. Constructing them is not supported (except for `MonkeyPatch`); they are only meant for use in type annotations. Doing so will emit a deprecation warning, and may become a hard-error in pytest 8.0. Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy. - :issue:`7527`: When a comparison between :func:`namedtuple <collections.namedtuple>` instances of the same type fails, pytest now shows the differing field names (possibly nested) instead of their indexes. - :issue:`7615`: :meth:`Node.warn <_pytest.nodes.Node.warn>` now permits any subclass of :class:`Warning`, not just :class:`PytestWarning <pytest.PytestWarning>`. - :issue:`7701`: Improved reporting when using ``--collected-only``. It will now show the number of collected tests in the summary stats. - :issue:`7710`: Use strict equality comparison for non-numeric types in :func:`pytest.approx` instead of raising :class:`TypeError`. This was the undocumented behavior before 3.7, but is now officially a supported feature. - :issue:`7938`: New ``--sw-skip`` argument which is a shorthand for ``--stepwise-skip``. - :issue:`8023`: Added ``'node_modules'`` to default value for :confval:`norecursedirs`. - :issue:`8032`: :meth:`doClassCleanups <unittest.TestCase.doClassCleanups>` (introduced in :mod:`unittest` in Python and 3.8) is now called appropriately. Bug Fixes --------- - :issue:`4824`: Fixed quadratic behavior and improved performance of collection of items using autouse fixtures and xunit fixtures. - :issue:`7758`: Fixed an issue where some files in packages are getting lost from ``--lf`` even though they contain tests that failed. Regressed in pytest 5.4.0. - :issue:`7911`: Directories created by by :fixture:`tmp_path` and :fixture:`tmpdir` are now considered stale after 3 days without modification (previous value was 3 hours) to avoid deleting directories still in use in long running test suites. - :issue:`7913`: Fixed a crash or hang in :meth:`pytester.spawn <_pytest.pytester.Pytester.spawn>` when the :mod:`readline` module is involved. - :issue:`7951`: Fixed handling of recursive symlinks when collecting tests. - :issue:`7981`: Fixed symlinked directories not being followed during collection. Regressed in pytest 6.1.0. - :issue:`8016`: Fixed only one doctest being collected when using ``pytest --doctest-modules path/to/an/__init__.py``. Improved Documentation ---------------------- - :issue:`7429`: Add more information and use cases about skipping doctests. - :issue:`7780`: Classes which should not be inherited from are now marked ``final class`` in the API reference. - :issue:`7872`: ``_pytest.config.argparsing.Parser.addini()`` accepts explicit ``None`` and ``"string"``. - :issue:`7878`: In pull request section, ask to commit after editing changelog and authors file. Trivial/Internal Changes ------------------------ - :issue:`7802`: The ``attrs`` dependency requirement is now >=19.2.0 instead of >=17.4.0. - :issue:`8014`: `.pyc` files created by pytest's assertion rewriting now conform to the newer :pep:`552` format on Python>=3.7. (These files are internal and only interpreted by pytest itself.) ``` ### 6.1.2 ``` ========================= Bug Fixes --------- - :issue:`7758`: Fixed an issue where some files in packages are getting lost from ``--lf`` even though they contain tests that failed. Regressed in pytest 5.4.0. - :issue:`7911`: Directories created by `tmpdir` are now considered stale after 3 days without modification (previous value was 3 hours) to avoid deleting directories still in use in long running test suites. Improved Documentation ---------------------- - :issue:`7815`: Improve deprecation warning message for ``pytest._fillfuncargs()``. ``` ### 6.1.1 ``` ========================= Bug Fixes --------- - :issue:`7807`: Fixed regression in pytest 6.1.0 causing incorrect rootdir to be determined in some non-trivial cases where parent directories have config files as well. - :issue:`7814`: Fixed crash in header reporting when :confval:`testpaths` is used and contains absolute paths (regression in 6.1.0). ``` ### 6.1.0 ``` ========================= Breaking Changes ---------------- - :issue:`5585`: As per our policy, the following features which have been deprecated in the 5.X series are now removed: * The ``funcargnames`` read-only property of ``FixtureRequest``, ``Metafunc``, and ``Function`` classes. Use ``fixturenames`` attribute. * ``pytest.fixture`` no longer supports positional arguments, pass all arguments by keyword instead. * Direct construction of ``Node`` subclasses now raise an error, use ``from_parent`` instead. * The default value for ``junit_family`` has changed to ``xunit2``. If you require the old format, add ``junit_family=xunit1`` to your configuration file. * The ``TerminalReporter`` no longer has a ``writer`` attribute. Plugin authors may use the public functions of the ``TerminalReporter`` instead of accessing the ``TerminalWriter`` object directly. * The ``--result-log`` option has been removed. Users are recommended to use the `pytest-reportlog <https://github.com/pytest-dev/pytest-reportlog>`__ plugin instead. For more information consult :std:doc:`deprecations` in the docs. Deprecations ------------ - :issue:`6981`: The ``pytest.collect`` module is deprecated: all its names can be imported from ``pytest`` directly. - :issue:`7097`: The ``pytest._fillfuncargs`` function is deprecated. This function was kept for backward compatibility with an older plugin. It's functionality is not meant to be used directly, but if you must replace it, use `function._request._fillfixtures()` instead, though note this is not a public API and may break in the future. - :issue:`7210`: The special ``-k '-expr'`` syntax to ``-k`` is deprecated. Use ``-k 'not expr'`` instead. The special ``-k 'expr:'`` syntax to ``-k`` is deprecated. Please open an issue if you use this and want a replacement. - :issue:`7255`: The :hook:`pytest_warning_captured` hook is deprecated in favor of :hook:`pytest_warning_recorded`, and will be removed in a future version. - :issue:`7648`: The ``gethookproxy()`` and ``isinitpath()`` methods of ``FSCollector`` and ``Package`` are deprecated; use ``self.session.gethookproxy()`` and ``self.session.isinitpath()`` instead. This should work on all pytest versions. Features -------- - :issue:`7667`: New ``--durations-min`` command-line flag controls the minimal duration for inclusion in the slowest list of tests shown by ``--durations``. Previously this was hard-coded to ``0.005s``. Improvements ------------ - :issue:`6681`: Internal pytest warnings issued during the early stages of initialization are now properly handled and can filtered through :confval:`filterwarnings` or ``--pythonwarnings/-W``. This also fixes a number of long standing issues: :issue:`2891`, :issue:`7620`, :issue:`7426`. - :issue:`7572`: When a plugin listed in ``required_plugins`` is missing or an unknown config key is used with ``--strict-config``, a simple error message is now shown instead of a stacktrace. - :issue:`7685`: Added two new attributes :attr:`rootpath <_pytest.config.Config.rootpath>` and :attr:`inipath <_pytest.config.Config.inipath>` to :class:`Config <_pytest.config.Config>`. These attributes are :class:`pathlib.Path` versions of the existing :attr:`rootdir <_pytest.config.Config.rootdir>` and :attr:`inifile <_pytest.config.Config.inifile>` attributes, and should be preferred over them when possible. - :issue:`7780`: Public classes which are not designed to be inherited from are now marked :func:`final <typing.final>`. Code which inherits from these classes will trigger a type-checking (e.g. mypy) error, but will still work in runtime. Currently the ``final`` designation does not appear in the API Reference but hopefully will in the future. Bug Fixes --------- - :issue:`1953`: Fixed error when overwriting a parametrized fixture, while also reusing the super fixture value. .. code-block:: python conftest.py import pytest pytest.fixture(params=[1, 2]) def foo(request): return request.param test_foo.py import pytest pytest.fixture def foo(foo): return foo * 2 - :issue:`4984`: Fixed an internal error crash with ``IndexError: list index out of range`` when collecting a module which starts with a decorated function, the decorator raises, and assertion rewriting is enabled. - :issue:`7591`: pylint shouldn't complain anymore about unimplemented abstract methods when inheriting from :ref:`File <non-python tests>`. - :issue:`7628`: Fixed test collection when a full path without a drive letter was passed to pytest on Windows (for example ``\projects\tests\test.py`` instead of ``c:\projects\tests\pytest.py``). - :issue:`7638`: Fix handling of command-line options that appear as paths but trigger an OS-level syntax error on Windows, such as the options used internally by ``pytest-xdist``. - :issue:`7742`: Fixed INTERNALERROR when accessing locals / globals with faulty ``exec``. Improved Documentation ---------------------- - :issue:`1477`: Removed faq.rst and its reference in contents.rst. Trivial/Internal Changes ------------------------ - :issue:`7536`: The internal ``junitxml`` plugin has rewritten to use ``xml.etree.ElementTree``. The order of attributes in XML elements might differ. Some unneeded escaping is no longer performed. - :issue:`7587`: The dependency on the ``more-itertools`` package has been removed. - :issue:`7631`: The result type of :meth:`capfd.readouterr() <_pytest.capture.CaptureFixture.readouterr>` (and similar) is no longer a namedtuple, but should behave like one in all respects. This was done for technical reasons. - :issue:`7671`: When collecting tests, pytest finds test classes and functions by examining the attributes of python objects (modules, classes and instances). To speed up this process, pytest now ignores builtin attributes (like ``__class__``, ``__delattr__`` and ``__new__``) without consulting the :confval:`python_classes` and :confval:`python_functions` configuration options and without passing them to plugins using the :hook:`pytest_pycollect_makeitem` hook. ``` ### 6.0.2 ``` ========================= Bug Fixes --------- - :issue:`7148`: Fixed ``--log-cli`` potentially causing unrelated ``print`` output to be swallowed. - :issue:`7672`: Fixed log-capturing level restored incorrectly if ``caplog.set_level`` is called more than once. - :issue:`7686`: Fixed `NotSetType.token` being used as the parameter ID when the parametrization list is empty. Regressed in pytest 6.0.0. - :issue:`7707`: Fix internal error when handling some exceptions that contain multiple lines or the style uses multiple lines (``--tb=line`` for example). ``` ### 6.0.1 ``` ========================= Bug Fixes --------- - :issue:`7394`: Passing an empty ``help`` value to ``Parser.add_option`` is now accepted instead of crashing when running ``pytest --help``. Passing ``None`` raises a more informative ``TypeError``. - :issue:`7558`: Fix pylint ``not-callable`` lint on ``pytest.mark.parametrize()`` and the other builtin marks: ``skip``, ``skipif``, ``xfail``, ``usefixtures``, ``filterwarnings``. - :issue:`7559`: Fix regression in plugins using ``TestReport.longreprtext`` (such as ``pytest-html``) when ``TestReport.longrepr`` is not a string. - :issue:`7569`: Fix logging capture handler's level not reset on teardown after a call to ``caplog.set_level()``. ``` ### 6.0.0 ``` ========================= (**Please see the full set of changes for this release also in the 6.0.0rc1 notes below**) Breaking Changes ---------------- - :issue:`5584`: **PytestDeprecationWarning are now errors by default.** Following our plan to remove deprecated features with as little disruption as possible, all warnings of type ``PytestDeprecationWarning`` now generate errors instead of warning messages. **The affected features will be effectively removed in pytest 6.1**, so please consult the :std:doc:`deprecations` section in the docs for directions on how to update existing code. In the pytest ``6.0.X`` series, it is possible to change the errors back into warnings as a stopgap measure by adding this to your ``pytest.ini`` file: .. code-block:: ini [pytest] filterwarnings = ignore::pytest.PytestDeprecationWarning But this will stop working when pytest ``6.1`` is released. **If you have concerns** about the removal of a specific feature, please add a comment to :issue:`5584`. - :issue:`7472`: The ``exec_()`` and ``is_true()`` methods of ``_pytest._code.Frame`` have been removed. Features -------- - :issue:`7464`: Added support for :envvar:`NO_COLOR` and :envvar:`FORCE_COLOR` environment variables to control colored output. Improvements ------------ - :issue:`7467`: ``--log-file`` CLI option and ``log_file`` ini marker now create subdirectories if needed. - :issue:`7489`: The :func:`pytest.raises` function has a clearer error message when ``match`` equals the obtained string but is not a regex match. In this case it is suggested to escape the regex. Bug Fixes --------- - :issue:`7392`: Fix the reported location of tests skipped with ``pytest.mark.skip`` when ``--runxfail`` is used. - :issue:`7491`: :fixture:`tmpdir` and :fixture:`tmp_path` no longer raise an error if the lock to check for stale temporary directories is not accessible. - :issue:`7517`: Preserve line endings when captured via ``capfd``. - :issue:`7534`: Restored the previous formatting of ``TracebackEntry.__str__`` which was changed by accident. Improved Documentation ---------------------- - :issue:`7422`: Clarified when the ``usefixtures`` mark can apply fixtures to test. - :issue:`7441`: Add a note about ``-q`` option used in getting started guide. Trivial/Internal Changes ------------------------ - :issue:`7389`: Fixture scope ``package`` is no longer considered experimental. ``` ### 6.0.0rc1 ``` ============================ Breaking Changes ---------------- - :issue:`1316`: ``TestReport.longrepr`` is now always an instance of ``ReprExceptionInfo``. Previously it was a ``str`` when a test failed with ``pytest.fail(..., pytrace=False)``. - :issue:`5965`: symlinks are no longer resolved during collection and matching `conftest.py` files with test file paths. Resolving symlinks for the current directory and during collection was introduced as a bugfix in 3.9.0, but it actually is a new feature which had unfortunate consequences in Windows and surprising results in other platforms. The team decided to step back on resolving symlinks at all, planning to review this in the future with a more solid solution (see discussion in :pull:`6523` for details). This might break test suites which made use of this feature; the fix is to create a symlink for the entire test tree, and not only to partial files/tress as it was possible previously. - :issue:`6505`: ``Testdir.run().parseoutcomes()`` now always returns the parsed nouns in plural form. Originally ``parseoutcomes()`` would always returns the nouns in plural form, but a change meant to improve the terminal summary by using singular form single items (``1 warning`` or ``1 error``) caused an unintended regression by changing the keys returned by ``parseoutcomes()``. Now the API guarantees to always return the plural form, so calls like this: .. code-block:: python result = testdir.runpytest() result.assert_outcomes(error=1) Need to be changed to: .. code-block:: python result = testdir.runpytest() result.assert_outcomes(errors=1) - :issue:`6903`: The ``os.dup()`` function is now assumed to exist. We are not aware of any supported Python 3 implementations which do not provide it. - :issue:`7040`: ``-k`` no longer matches against the names of the directories outside the test session root. Also, ``pytest.Package.name`` is now just the name of the directory containing the package's ``__init__.py`` file, instead of the full path. This is consistent with how the other nodes are named, and also one of the reasons why ``-k`` would match against any directory containing the test suite. - :issue:`7122`: Expressions given to the ``-m`` and ``-k`` options are no longer evaluated using Python's :func:`eval`. The format supports ``or``, ``and``, ``not``, parenthesis and general identifiers to match against. Python constants, keywords or other operators are no longer evaluated differently. - :issue:`7135`: Pytest now uses its own ``TerminalWriter`` class instead of using the one from the ``py`` library. Plugins generally access this class through ``TerminalReporter.writer``, ``TerminalReporter.write()`` (and similar methods), or ``_pytest.config.create_terminal_writer()``. The following breaking changes were made: - Output (``write()`` method and others) no longer flush implicitly; the flushing behavior of the underlying file is respected. To flush explicitly (for example, if you want output to be shown before an end-of-line is printed), use ``write(flush=True)`` or ``terminal_writer.flush()``. - Explicit Windows console support was removed, delegated to the colorama library. - Support for writing ``bytes`` was removed. - The ``reline`` method and ``chars_on_current_line`` property were removed. - The ``stringio`` and ``encoding`` arguments was removed. - Support for passing a callable instead of a file was removed. - :issue:`7224`: The `item.catch_log_handler` and `item.catch_log_handlers` attributes, set by the logging plugin and never meant to be public, are no longer available. The deprecated ``--no-print-logs`` option and ``log_print`` ini option are removed. Use ``--show-capture`` instead. - :issue:`7226`: Removed the unused ``args`` parameter from ``pytest.Function.__init__``. - :issue:`7418`: Removed the `pytest_doctest_prepare_content` hook specification. This hook hasn't been triggered by pytest for at least 10 years. - :issue:`7438`: Some changes were made to the internal ``_pytest._code.source``, listed here for the benefit of plugin authors who may be using it: - The ``deindent`` argument to ``Source()`` has been removed, now it is always true. - Support for zero or multiple arguments to ``Source()`` has been removed. - Support for comparing ``Source`` with an ``str`` has been removed. - The methods ``Source.isparseable()`` and ``Source.putaround()`` have been removed. - The method ``Source.compile()`` and function ``_pytest._code.compile()`` have been removed; use plain ``compile()`` instead. - The function ``_pytest._code.source.getsource()`` has been removed; use ``Source()`` directly instead. Deprecations ------------ - :issue:`7210`: The special ``-k '-expr'`` syntax to ``-k`` is deprecated. Use ``-k 'not expr'`` instead. The special ``-k 'expr:'`` syntax to ``-k`` is deprecated. Please open an issue if you use this and want a replacement. - :issue:`4049`: ``pytest_warning_captured`` is deprecated in favor of the ``pytest_warning_recorded`` hook. Features -------- - :issue:`1556`: pytest now supports ``pyproject.toml`` files for configuration. The configuration options is similar to the one available in other formats, but must be defined in a ``[tool.pytest.ini_options]`` table to be picked up by pytest: .. code-block:: toml pyproject.toml [tool.pytest.ini_options] minversion = "6.0" addopts = "-ra -q" testpaths = [ "tests", "integration", ] More information can be found :ref:`in the docs <config file formats>`. - :issue:`3342`: pytest now includes inline type annotations and exposes them to user programs. Most of the user-facing API is covered, as well as internal code. If you are running a type checker such as mypy on your tests, you may start noticing type errors indicating incorrect usage. If you run into an error that you believe to be incorrect, please let us know in an issue. The types were developed against mypy version 0.780. Versions before 0.750 are known not to work. We recommend using the latest version. Other type checkers may work as well, but they are not officially verified to work by pytest yet. - :issue:`4049`: Introduced a new hook named `pytest_warning_recorded` to convey information about warnings captured by the internal `pytest` warnings plugin. This hook is meant to replace `pytest_warning_captured`, which is deprecated and will be removed in a future release. - :issue:`6471`: New command-line flags: * `--no-header`: disables the initial header, including platform, version, and plugins. * `--no-summary`: disables the final test summary, including warnings. - :issue:`6856`: A warning is now shown when an unknown key is read from a config INI file. The `--strict-config` flag has been added to treat these warnings as errors. - :issue:`6906`: Added `--code-highlight` command line option to enable/disable code highlighting in terminal output. - :issue:`7245`: New ``--import-mode=importlib`` option that uses :mod:`importlib` to import test modules. Traditionally pytest used ``__import__`` while changing ``sys.path`` to import test modules (which also changes ``sys.modules`` as a side-effect), which works but has a number of drawbacks, like requiring test modules that don't live in packages to have unique names (as they need to reside under a unique name in ``sys.modules``). ``--import-mode=importlib`` uses more fine grained import mechanisms from ``importlib`` which don't require pytest to change ``sys.path`` or ``sys.modules`` at all, eliminating much of the drawbacks of the previous mode. We intend to make ``--import-mode=importlib`` the default in future versions, so users are encouraged to try the new mode and provide feedback (both positive or negative) in issue :issue:`7245`. You can read more about this option in :std:ref:`the documentation <import-modes>`. - :issue:`7305`:
