A flake8 plugin checking common style issues or inconsistencies with pytest-based tests.
Currently the following errors are reported:
| Code | Description |
|---|---|
| PT001 | use @pytest.fixture() over @pytest.fixture (configurable by pytest-fixture-no-parentheses) |
| PT002 | configuration for fixture '{name}' specified via positional args, use kwargs |
| PT003 | scope='function' is implied in @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} (configurable by pytest-parametrize-names-type) |
| PT007 | wrong values type in @pytest.mark.parametrize, expected {expected_type} (configurable by pytest-parametrize-values-type and pytest-parametrize-values-row-type) |
| PT008 | use return_value= instead of patching with lambda |
| PT009 | use a regular assert instead of unittest-style '{assertion}' |
| PT010 | set the expected exception in pytest.raises() |
| PT011 | pytest.raises({exception}) is too broad, set the match parameter or use a more specific exception (configurable by pytest-raises-require-match-for) |
| PT012 | pytest.raises() block should contain a single simple statement |
| PT013 | found incorrect import of pytest, use simple 'import pytest' instead |
| PT014 | found duplicate test cases {indexes} in @pytest.mark.parametrize |
| PT015 | assertion always fails, replace with pytest.fail() |
| PT016 | no message passed to pytest.fail() |
| PT017 | found assertion on exception {name} in except block, use pytest.raises() instead |
| PT018 | assertion should be broken down into multiple parts |
| PT019 | fixture {name} without value is injected as parameter, use @pytest.mark.usefixtures instead |
| PT020 | @pytest.yield_fixture is deprecated, use @pytest.fixture |
| PT021 | use yield instead of request.addfinalizer |
| PT022 | no teardown in fixture {name}, use return instead of yield |
| PT023 | use @pytest.mark.foo() over @pytest.mark.foo (configurable by pytest-mark-no-parentheses) |
| PT024 | pytest.mark.asyncio is unnecessary for fixtures |
| PT025 | pytest.mark.usefixtures has no effect on fixtures |
| PT026 | useless pytest.mark.usefixtures without parameters |
| PT027 | use pytest.raises() instead of unittest-style '{assertion}' |
