Release notes

Sourced from pytest's releases.

7.0.0

pytest 7.0.0 (2022-02-03)

(Please see the full set of changes for this release also in the 7.0.0rc1 notes below)

Deprecations

• #9488: If custom subclasses of nodes like pytest.Item{.interpreted-text role="class"} override the __init__ method, they should take **kwargs. See uncooperative-constructors-deprecated{.interpreted-text role="ref"} for details.

  Note that a deprection warning is only emitted when there is a conflict in the arguments pytest expected to pass. This deprecation was already part of pytest 7.0.0rc1 but wasn't documented.

Bug Fixes

• #9355: Fixed error message prints function decorators when using assert in Python 3.8 and above.
• #9396: Ensure pytest.Config.inifile{.interpreted-text role="attr"} is available during the pytest_cmdline_main <_pytest.hookspec.pytest_cmdline_main>{.interpreted-text role="func"} hook (regression during 7.0.0rc1).

Improved Documentation

• #9404: Added extra documentation on alternatives to common misuses of [pytest.warns(None)]{.title-ref} ahead of its deprecation.
• #9505: Clarify where the configuration files are located. To avoid confusions documentation mentions that configuration file is located in the root of the repository.

Trivial/Internal Changes

• #9521: Add test coverage to assertion rewrite path.

pytest 7.0.0rc1 (2021-12-06)

Breaking Changes

• #7259: The Node.reportinfo() <non-python tests>{.interpreted-text role="ref"} function first return value type has been expanded from [py.path.local | str]{.title-ref} to [os.PathLike[str] | str]{.title-ref}.

  Most plugins which refer to [reportinfo()]{.title-ref} only define it as part of a custom pytest.Item{.interpreted-text role="class"} implementation. Since [py.path.local]{.title-ref} is a [os.PathLike[str]]{.title-ref}, these plugins are unaffacted.

  Plugins and users which call [reportinfo()]{.title-ref}, use the first return value and interact with it as a [py.path.local]{.title-ref}, would need to adjust by calling [py.path.local(fspath)]{.title-ref}. Although preferably, avoid the legacy [py.path.local]{.title-ref} and use [pathlib.Path]{.title-ref}, or use [item.location]{.title-ref} or [item.path]{.title-ref}, instead.

  Note: pytest was not able to provide a deprecation period for this change.
