pytest-fixture-typecheck is a pytest plugin that inserts runtime assertions that your fixture usages are properly typed.
Pytest fixtures are magic that mypy does not understand. This typechecks just fine:
@pytest.fixture
def myint():
return 42
def test_basic(myint: str):
assert myint == 42
This test passes but the type annotation is wrong.
With this pytest plugin it will pass typechecking all the same, but your test will fail at least.
If your tests do not have type annotations, this plugin does nothing. Use mypy to enforce that everything has type annotations.
Consider vendoring this package by copying its [5 lines of sourcecode](./pytest_fixture_typecheck.py) in your `conftest.py`. The package's metadata is larger than 5 lines.
