- Move the logic for running mypy on the test cases from `tests/mypy_test.py` to a separate script, `tests/regr_test.py`. - Add the necessary logic in order to be able to have test cases for third-party stubs. - Move logic common to `tests/mypy_test.py` and `tests/regr_test.py` into `tests/colors.py`, and rename `tests/colors.py` to `tests/utils.py`. - Add a new check to `tests/check_consistent.py`, to enforce the use of `# pyright: reportUnnecessaryTypeIgnoreComment=true` comments in third-party test cases. These are essential if we want to have our tests against false-negatives work with pyright. - Update the relevant documentation to account for the new test file. - Add a new job to the `tests.yml` GitHub workflow, to run the new test in CI. - Add a simple proof-of-concept test case for `requests`, as a regression test for #7998.
