Strict type-checking of tests using the default argument syntax

[hukkin]

Do you have plans for allowing strict type-checking of tests using the default argument syntax? The issue I see here is that the parameter should be annotated with the type of the value injected into the test, but the default argument has the type of the fixture that provides the value. It seems analogous to how dataclasses.field works, and would probably require a mypy plugin as well?

It may be possible to leverage typing.Annotated here - FastAPI recently started doing this for a similar pattern - https://github.com/tiangolo/fastapi/releases/tag/0.95.0
