Pytest fixture to usefixtures inspection¶

Pytest fixture to usefixtures inspection reports unused setup-only fixture parameters in tests and offers conversion to @pytest.mark.usefixtures(...).

How to use it¶

Open a test function that declares a setup-only fixture parameter and never references it in the test body. @pytest.mark.usefixtures(...) is the right replacement only when the fixture does not return or yield a value. Fixtures that provide a value stay as parameters so the unused result remains visible.

When it helps¶

Use this inspection to make setup-only fixture dependencies explicit without keeping unused parameters in the test signature.

Notes¶

• BetterPy updates decorators and imports pytest when needed.
• Pytest built-in fixtures such as capsys, tmp_path, monkeypatch, or pytester are never reported.
• The feature is gated by the Pytest fixture to usefixtures inspection setting under Settings | BetterPy | Testing (Pytest) | Fixture Inspections.
