Changelog

Sourced from pytest's changelog.

pytest 4.2.1 (2019-02-12)

Bug Fixes

• #2895: The pytest_report_collectionfinish hook now is also called with --collect-only.
• #3899: Do not raise UsageError when an imported package has a pytest_plugins.py child module.
• #4347: Fix output capturing when using pdb++ with recursive debugging.
• #4592: Fix handling of collect_ignore via parent conftest.py.
• #4700: Fix regression where setUpClass would always be called in subclasses even if all tests were skipped by a unittest.skip() decorator applied in the subclass.
• #4739: Fix parametrize(... ids=<function>) when the function returns non-strings.
• #4745: Fix/improve collection of args when passing in __init__.py and a test file.
• #4770: more_itertools is now constrained to <6.0.0 when required for Python 2.7 compatibility.
• #526: Fix "ValueError: Plugin already registered" exceptions when running in build directories that symlink to actual source.

Improved Documentation

• #3899: Add note to plugins.rst that pytest_plugins should not be used as a name for a user module containing plugins.
• #4324: Document how to use raises and does_not_raise to write parametrized tests with conditional raises.
• #4709: Document how to customize test failure messages when using pytest.warns.

Trivial/Internal Changes

• #4741: Some verbosity related attributes of the TerminalReporter plugin are now read only properties.

pytest 4.2.0 (2019-01-30)

Features

• #3094: Classic xunit-style functions and methods now obey the scope of autouse fixtures.

  This fixes a number of surprising issues like setup_method being called before session-scoped autouse fixtures (see #517 for an example).

• #4627: Display a message at the end of the test session when running under Python 2.7 and 3.4 that pytest 5.0 will no longer support those Python versions.

• #4660: The number of selected tests now are also displayed when the -k or -m flags are used.

• #4688: pytest_report_teststatus hook now can also receive a config parameter.

• #4691: pytest_terminal_summary hook now can also receive a config parameter.

Bug Fixes

• #3547: --junitxml can emit XML compatible with Jenkins xUnit. junit_family INI option accepts legacy|xunit1, which produces old style output, and xunit2 that conforms more strictly to https://github.com/jenkinsci/xunit-plugin/blob/xunit-2.3.2/src/main/resources/org/jenkinsci/plugins/xunit/types/model/xsd/junit-10.xsd

• #4280: Improve quitting from pdb, especially with --trace.

  Using q[quit] after pdb.set_trace() will quit pytest also.
