Pytest-mypy treats mypy annotation-unchecked warning as error

[nidico]

Since mypy 0.990, mypy emits a warning if a variable is annotated in a function without type annotation, see mypy 0.990 release notes.

Such a warning ends up being reported as a test failure in pytest-mypy, erroneously.

Thanks for the report 🙂 I am able to reproduce it.
