8.4.0

pytest 8.4.0 (2025-06-02)

Removals and backward incompatible breaking changes

• #11372: Async tests will now fail, instead of warning+skipping, if you don't have any suitable plugin installed.

• #12346: Tests will now fail, instead of raising a warning, if they return any value other than None.

• #12874: We dropped support for Python 3.8 following its end of life (2024-10-07).

• #12960: Test functions containing a yield now cause an explicit error. They have not been run since pytest 4.0, and were previously marked as an expected failure and deprecation warning.

  See the docs <yield tests deprecated>{.interpreted-text role="ref"} for more information.

Deprecations (removal in next major release)

• #10839: Requesting an asynchronous fixture without a [pytest_fixture_setup]{.title-ref} hook that resolves it will now give a DeprecationWarning. This most commonly happens if a sync test requests an async fixture. This should have no effect on a majority of users with async tests or fixtures using async pytest plugins, but may affect non-standard hook setups or autouse=True. For guidance on how to work around this warning see sync-test-async-fixture{.interpreted-text role="ref"}.

New features

• #11538: Added pytest.RaisesGroup{.interpreted-text role="class"} as an equivalent to pytest.raises{.interpreted-text role="func"} for expecting ExceptionGroup{.interpreted-text role="exc"}. Also adds pytest.RaisesExc{.interpreted-text role="class"} which is now the logic behind pytest.raises{.interpreted-text role="func"} and used as parameter to pytest.RaisesGroup{.interpreted-text role="class"}. RaisesGroup includes the ability to specify multiple different expected exceptions, the structure of nested exception groups, and flags for emulating except* <except_star>{.interpreted-text role="ref"}. See assert-matching-exception-groups{.interpreted-text role="ref"} and docstrings for more information.

• #12081: Added capteesys{.interpreted-text role="fixture"} to capture AND pass output to next handler set by --capture=.

• #12504: pytest.mark.xfail{.interpreted-text role="func"} now accepts pytest.RaisesGroup{.interpreted-text role="class"} for the raises parameter when you expect an exception group. You can also pass a pytest.RaisesExc{.interpreted-text role="class"} if you e.g. want to make use of the check parameter.

• #12713: New [--force-short-summary]{.title-ref} option to force condensed summary output regardless of verbosity level.

  This lets users still see condensed summary output of failures for quick reference in log files from job outputs, being especially useful if non-condensed output is very verbose.

• #12749: pytest traditionally collects classes/functions in the test module namespace even if they are imported from another file.

  For example:

  # contents of src/domain.py
  class Testament: ...
  contents of tests/test_testament.py
  from domain import Testament
  def test_testament(): ...

  In this scenario with the default options, pytest will collect the class [Testament]{.title-ref} from [tests/test_testament.py]{.title-ref} because it starts with [Test]{.title-ref}, even though in this case it is a production class being imported in the test module namespace.

  This behavior can now be prevented by setting the new collect_imported_tests{.interpreted-text role="confval"} configuration option to false, which will make pytest collect classes/functions from test files only if they are defined in that file.

6.2.0 (2025-06-11)

• The plugin now adds 3 rules in the filter warnings configuration to prevent common coverage warnings being raised as obscure errors::

  default:unclosed database in <sqlite3.Connection object at:ResourceWarning once::PytestCovWarning once::CoverageWarning

  This fixes most of the bad interactions that are occurring on pytest 8.4 with filterwarnings=error.

  The plugin will check if there already matching rules for the 3 categories (ResourceWarning, PytestCovWarning, CoverageWarning) and message (unclosed database in <sqlite3.Connection object at) before adding the filters.

  This means you can have this in your pytest configuration for complete oblivion (not recommended, if that is not clear)::

  filterwarnings = [ "error", "ignore:unclosed database in <sqlite3.Connection object at:ResourceWarning", "ignore::PytestCovWarning", "ignore::CoverageWarning", ]
