5585.breaking.rst

As per our policy, the following features have been deprecated in the 5.X series and are now removed:

• The funcargnames read-only property of FixtureRequest, Metafunc, and Function classes. Use fixturenames attribute.
• @pytest.fixture no longer supports positional arguments, pass all arguments by keyword instead.
• Direct construction of Node subclasses now raise an error, use from_parent instead.
• The default value for junit_family has changed to xunit2. If you require the old format, add junit_family=xunit1 to your configuration file.
• The TerminalReporter no longer has a writer attribute. Plugin authors may use the public functions of the TerminalReporter instead of accessing the TerminalWriter object directly.
• The --result-log option has been removed. Users are recommended to use the pytest-reportlog plugin instead.
