Changelog

### 5.1.3 ``` ========================= Bug Fixes --------- - `5807 <https://github.com/pytest-dev/pytest/issues/5807>`_: Fix pypy3.6 (nightly) on windows. - `5811 <https://github.com/pytest-dev/pytest/issues/5811>`_: Handle ``--fulltrace`` correctly with ``pytest.raises``. - `5819 <https://github.com/pytest-dev/pytest/issues/5819>`_: Windows: Fix regression with conftest whose qualified name contains uppercase characters (introduced by 5792). ``` ### 5.1.2 ``` ========================= Bug Fixes --------- - `2270 <https://github.com/pytest-dev/pytest/issues/2270>`_: Fixed ``self`` reference in function-scoped fixtures defined plugin classes: previously ``self`` would be a reference to a *test* class, not the *plugin* class. - `570 <https://github.com/pytest-dev/pytest/issues/570>`_: Fixed long standing issue where fixture scope was not respected when indirect fixtures were used during parametrization. - `5782 <https://github.com/pytest-dev/pytest/issues/5782>`_: Fix decoding error when printing an error response from ``--pastebin``. - `5786 <https://github.com/pytest-dev/pytest/issues/5786>`_: Chained exceptions in test and collection reports are now correctly serialized, allowing plugins like ``pytest-xdist`` to display them properly. - `5792 <https://github.com/pytest-dev/pytest/issues/5792>`_: Windows: Fix error that occurs in certain circumstances when loading ``conftest.py`` from a working directory that has casing other than the one stored in the filesystem (e.g., ``c:\test`` instead of ``C:\test``). ```
