We’ve just uploaded mypy 1.10 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:
python3 -m pip install -U mypy
You can read the full documentation for this release on Read the Docs.
Support TypeIs (PEP 742)
Mypy now supports TypeIs (PEP 742), which allows
functions to narrow the type of a value, similar to isinstance(). Unlike TypeGuard,
TypeIs can narrow in both the if and else branches of an if statement:
#12069: A deprecation warning is now raised when implementations of one of the following hooks request a deprecated py.path.local parameter instead of the pathlib.Path parameter which replaced it:
pytest_ignore_collect{.interpreted-text role="hook"} - the path parameter - use collection_path instead.
pytest_collect_file{.interpreted-text role="hook"} - the path parameter - use file_path instead.
pytest_pycollect_makemodule{.interpreted-text role="hook"} - the path parameter - use module_path instead.
pytest_report_header{.interpreted-text role="hook"} - the startdir parameter - use start_path instead.
pytest_report_collectionfinish{.interpreted-text role="hook"} - the startdir parameter - use start_path instead.
The replacement parameters are available since pytest 7.0.0.
The old parameters will be removed in pytest 9.0.0.
See legacy-path-hooks-deprecated{.interpreted-text role="ref"} for more details.
Features
#11871: Added support for reading command line arguments from a file using the prefix character @, like e.g.: pytest @tests.txt. The file must have one argument per line.
See Read arguments from file <args-from-file>{.interpreted-text role="ref"} for details.
Improvements
#11523: pytest.importorskip{.interpreted-text role="func"} will now issue a warning if the module could be found, but raised ImportError{.interpreted-text role="class"} instead of ModuleNotFoundError{.interpreted-text role="class"}.
The warning can be suppressed by passing exc_type=ImportError to pytest.importorskip{.interpreted-text role="func"}.
See import-or-skip-import-error{.interpreted-text role="ref"} for details.
#11728: For unittest-based tests, exceptions during class cleanup (as raised by functions registered with TestCase.addClassCleanup <unittest.TestCase.addClassCleanup>{.interpreted-text role="meth"}) are now reported instead of silently failing.
#11777: Text is no longer truncated in the short test summary info section when -vv is given.
#12112: Improved namespace packages detection when consider_namespace_packages{.interpreted-text role="confval"} is enabled, covering more situations (like editable installs).
#9502: Added PYTEST_VERSION{.interpreted-text role="envvar"} environment variable which is defined at the start of the pytest session and undefined afterwards. It contains the value of pytest.__version__, and among other things can be used to easily check if code is running from within a pytest run.
Bug Fixes
#12065: Fixed a regression in pytest 8.0.0 where test classes containing setup_method and tests using @staticmethod or @classmethod would crash with AttributeError: 'NoneType' object has no attribute 'setup_method'.
Now the request.instance <pytest.FixtureRequest.instance>{.interpreted-text role="attr"} attribute of tests using @staticmethod and @classmethod is no longer None, but a fresh instance of the class, like in non-static methods.
