-   If you see that CI build is failing on a specific Python version and
-   you don't have this version on your computer, you can use the helper to
-   run it (only if you have docker)::
-
-     make test-<python-version>[-no-extensions]
-
-   For example, if you want to run tests for python3.10
-   without extensions, you can run this command::
-
-     make test-3.10-no-extensions
