 The :mod:`test` package can be run as a script to drive Python's regression

 the hood, it uses :mod:`test.regrtest`; the call :program:`python -m

-unittest.TestLoader.loadTestsFromModule if ``test_main`` does not exist.

 Running :mod:`test` directly allows what resources are available for
 tests to use to be set. You do this by using the ``-u`` command-line
