Updates pytest to 9.1.1

Release notes

9.1.1

pytest 9.1.1 (2026-06-19)

Bug fixes

• #14220: Fixed a logic bug in pytest.RaisesGroup which would might cause it to display incorrect "It matches FooError() which was paired with BarError" messages.
• #14591: Fixed a regression in pytest 9.1.0 which caused overriding a parametrized fixture with an indirect @​pytest.mark.parametrize to fail with "duplicate parametrization of '<fixture name>'".
• #14606: Fixed list-item typing errors from mypy in @pytest.mark.parametrize <pytest.mark.parametrize ref> argvalues parameter.
• #14608: Fixed a regression in pytest 9.1.0 where conftest.py files located in <invocation dir>/test* were no longer loaded as initial conftests when invoked without arguments. This could cause certain hooks (like pytest_addoption) in these files to not fire.

Updates pytest-cov to 7.1.0

Changelog

Sourced from pytest-cov's changelog.

7.1.0 (2026-03-21)

• Fixed total coverage computation to always be consistent, regardless of reporting settings. Previously some reports could produce different total counts, and consequently can make --cov-fail-under behave different depending on reporting options. See [#641](https://github.com/pytest-dev/pytest-cov/issues/641) <https://github.com/pytest-dev/pytest-cov/issues/641>_.

• Improve handling of ResourceWarning from sqlite3.

  The plugin adds warning filter for sqlite3 ResourceWarning unclosed database (since 6.2.0). It checks if there is already existing plugin for this message by comparing filter regular expression. When filter is specified on command line the message is escaped and does not match an expected message. A check for an escaped regular expression is added to handle this case.

  With this fix one can suppress ResourceWarning from sqlite3 from command line::

  pytest -W "ignore:unclosed database in <sqlite3.Connection object at:ResourceWarning" ...

• Various improvements to documentation. Contributed by Art Pelling in [#718](https://github.com/pytest-dev/pytest-cov/issues/718) <https://github.com/pytest-dev/pytest-cov/pull/718>_ and "vivodi" in [#738](https://github.com/pytest-dev/pytest-cov/issues/738) <https://github.com/pytest-dev/pytest-cov/pull/738>. Also closed [#736](https://github.com/pytest-dev/pytest-cov/issues/736) <https://github.com/pytest-dev/pytest-cov/issues/736>.

• Fixed some assertions in tests. Contributed by in Markéta Machová in [#722](https://github.com/pytest-dev/pytest-cov/issues/722) <https://github.com/pytest-dev/pytest-cov/pull/722>_.

• Removed unnecessary coverage configuration copying (meant as a backup because reporting commands had configuration side-effects before coverage 5.0).

7.0.0 (2025-09-09)

• Dropped support for subprocesses measurement.

  It was a feature added long time ago when coverage lacked a nice way to measure subprocesses created in tests. It relied on a .pth file, there was no way to opt-out and it created bad interactions with coverage's new patch system <https://coverage.readthedocs.io/en/latest/config.html#run-patch>_ added in 7.10 <https://coverage.readthedocs.io/en/7.10.6/changes.html#version-7-10-0-2025-07-24>_.

  To migrate to this release you might need to enable the suprocess patch, example for .coveragerc:

  .. code-block:: ini

  [run] patch = subprocess

  This release also requires at least coverage 7.10.6.

• Switched packaging to have metadata completely in pyproject.toml and use hatchling <https://pypi.org/project/hatchling/>_ for building. Contributed by Ofek Lev in [#551](https://github.com/pytest-dev/pytest-cov/issues/551) <https://github.com/pytest-dev/pytest-cov/pull/551>_ with some extras in [#716](https://github.com/pytest-dev/pytest-cov/issues/716) <https://github.com/pytest-dev/pytest-cov/pull/716>_.

• Removed some not really necessary testing deps like six.

Mypy Release Notes

Next Release

Mypy 2.4

We've just uploaded mypy 2.4.0 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.

Python 3.15 Support

Mypy 2.4 supports running on Python 3.15 and type checking most Python 3.15 features. This includes the new builtin sentinel type for sentinel values (PEP 661), which mypy now supports (see below for details). Lazy imports (PEP 810) and unpacking in comprehensions (PEP 798) are also supported. Closed TypedDicts (PEP 728) have been supported since mypy 2.2, but the extra_items TypedDict argument, also introduced in PEP 728, is still unsupported. Support for extra_items will be added in a future mypy release.

Native Parser Enabled by Default

Mypy now uses the new native parser by default. It's based on the Ruff parser, and it's significantly faster than the legacy parser, which uses the stdlib ast module. The native parser also has other benefits:

• You can target newer Python versions and use recent Python syntax even when running mypy on an older Python version. For example, you can use --python-version 3.15 when running mypy on Python 3.14.
• Stub files can use syntax that is newer than the target Python version. For example, stubs can use the PEP 695 generic class syntax (class Box[T]: ...) when running on or targeting Python 3.10.
• Parallel type checking requires the native parser.

The legacy parser is still available through --no-native-parser, or native_parser = False in the config file (native_parser = false under [tool.mypy] in pyproject.toml). We are planning to remove the legacy parser in early 2027. If you run into a problem with the native parser, please report it on the issue tracker.

Unlike the legacy parser, the native parser doesn't support type comments for variables defined by for and with statements. These type comments are silently ignored, and the types of the variables are
