All inspections provided by BetterPy. Each can be configured in Settings → Editor → Inspections → BetterPy.

Inspection	Maturity	Description	Group
@pytest.mark.usefixtures on fixture is a no-op inspection	Incubating	Reports @pytest.mark.usefixtures decorators on fixture functions, where they have no effect — pytest only honours usefixtures on test functions	Testing (Pytest)
Constant should be Final inspection	Stable	Reports module-level constants that should be annotated with Final	Code Quality & Safety
Fixture annotation mismatch inspection	Incubating	Reports test or fixture parameters whose explicit type annotation is incompatible with the value type provided by the resolved fixture	Testing (Pytest)
Missing \|None annotation inspection	Incubating	Adds a quickfix for PyCharm's missing \| None annotation inspection	Typing & Type Hints
Overridden method missing type annotations inspection	Incubating	Reports overrides missing type annotations present in parent methods	Typing & Type Hints
Private module import inspection	Stable	Reports private-module imports that should use public package exports	Code Quality & Safety
Pytest failed line inspection	Incubating	Marks the line where a pytest test failed	Testing (Pytest)
Pytest fixture direct import inspection	Incubating	Reports pytest fixture functions imported directly into conftest.py — prefer pytest_plugins for explicit scoping	Testing (Pytest)
Pytest fixture override contract inspection	Incubating	Reports fixture overrides whose produced value type is incompatible with the parent fixture	Testing (Pytest)
Pytest fixture scope inspection	Incubating	Reports fixtures that narrow the scope compared to parent fixtures	Testing (Pytest)
Pytest fixture uninjected reference inspection	Incubating	Reports fixture references inside tests/fixtures that are not declared as parameters	Testing (Pytest)
Pytest redundant fixture import inspection	Incubating	Reports explicitly imported pytest fixtures that are already auto-discoverable via conftest or plugins.	Testing (Pytest)
Shadowing stdlib module inspection	Stable	Reports project modules that shadow Python standard library modules	Code Quality & Safety
Unknown dynamic pytest fixture inspection	Incubating	Reports string-based fixture requests (usefixtures, getfixturevalue, indirect parametrize) that do not resolve to any visible fixture	Testing (Pytest)
Unused pytest fixture inspection	Incubating	Reports pytest fixture functions that are never used as a parameter in any test or other fixture in the project, and offers a safe-delete quick fix	Testing (Pytest)
pytest_plugins in non-root conftest inspection	Incubating	Reports pytest_plugins assignments that appear in a non-root conftest.py file, where they have no effect	Testing (Pytest)
request.param without params inspection	Incubating	Reports pytest fixtures that read request.param but declare no params= and are not the target of any indirect parametrization	Testing (Pytest)
