Changelog

3.2.2

=========================

Bug Fixes

• Calling the deprecated request.getfuncargvalue() now shows the source of
  the call. (2681 <https://github.com/pytest-dev/pytest/issues/2681>_)

• Allow tests declared as staticmethod to use fixtures. (2699 <https://github.com/pytest-dev/pytest/issues/2699>_)

• Fixed edge-case during collection: attributes which raised pytest.fail
  when accessed would abort the entire collection. (2707 <https://github.com/pytest-dev/pytest/issues/2707>_)

• Fix ReprFuncArgs with mixed unicode and UTF-8 args. (2731 <https://github.com/pytest-dev/pytest/issues/2731>_)

Improved Documentation

• In examples on working with custom markers, add examples demonstrating the
  usage of pytest.mark.MARKER_NAME.with_args in comparison with
  pytest.mark.MARKER_NAME.__call__ (2604 <https://github.com/pytest-dev/pytest/issues/2604>_)

• In one of the simple examples, use pytest_collection_modifyitems() to skip
  tests based on a command-line option, allowing its sharing while preventing a
  user error when acessing pytest.config before the argument parsing. (2653 <https://github.com/pytest-dev/pytest/issues/2653>_)

Trivial/Internal Changes

• Fixed minor error in 'Good Practices/Manual Integration' code snippet.
  (2691 <https://github.com/pytest-dev/pytest/issues/2691>_)

• Fixed typo in goodpractices.rst. (2721 <https://github.com/pytest-dev/pytest/issues/2721>_)

• Improve user guidance regarding --resultlog deprecation. (2739 <https://github.com/pytest-dev/pytest/issues/2739>_)
