Description
Bug Report
When using pytest-mypy to test some dynamically determined types (with generics) results in a false-positive error in CI, because mypy's exit code becomes 1 when there are no errors but only reveal_type outputs.
To Reproduce
Just write an arbitrary Python file that has no type errors and put reveal_type() to any one of the identifiers.
Run mypy against that file and check the exit code.
I'd like to keep reveal_type() in my code, to test a mixture of runtime type validation and static typing results using typeguard, generics, and pytest-mypy plugin.
Expected Behavior
When there are no errors but only some reveal_type outputs, mypy executable should set the exit code 0.
Actual Behavior
It sets the exit code 1, breaking my CI.
