A flake8 plugin checking common style issues or inconsistencies with pytest-based tests.

Currently the following errors are reported:

  • PT001 use @pytest.fixture() over @pytest.fixture

  • PT002 configuration for fixture '{name}' specified via positional args, use kwargs
    e.g. @pytest.fixture(scope='module') is OK, and @pytest.fixture('module') is an error

  • PT003 scope='function' is implied in @pytest.fixture()
    e.g. @pytest.fixture(scope='function') should be replaced with @pytest.fixture()

  • PT004 fixture '{name}' does not return anything, add leading underscore

  • PT005 fixture '{name}' returns a value, remove leading underscore

  • PT006 wrong name(s) type in @pytest.mark.parametrize, expected {expected_type}
    e.g. @pytest.mark.parametrize(('name1', 'name2'), ...) is ok, and @pytest.mark.parametrize('name1,name2', ...) is an error

  • PT007 wrong values type in @pytest.mark.parametrize, expected {expected_type}

  • PT008 use return_value= instead of patching with lambda
    e.g. mocker.patch('target', return_value=7) is OK, and mocker.patch('target', lambda *args: 7) is an error
