.. note::
Calling ``pytest.main()`` will result in importing your tests and any modules
that they import. Due to the caching mechanism of python's import system,
making subsequent calls to ``pytest.main()`` from the same process will not
reflect changes to those files between the calls. For this reason, making
multiple calls to ``pytest.main()`` from the same process (in order to re-run
tests, for example) is not recommended.
