One way to enforce this order is to make the function-level fixture depend
on the module-level fixture (common_configuration?):

    @pytest.fixture(scope='module')
    def common_configuration():
        ...

    @pytest.fixture(autouse=True)
    def function_level_configuration(common_configuration):
        ...

This is unfortunately a common source of confusion, but
"@pytest.mark.usefixtures" only works for test items, not fixtures and
hooks. But I believe there's a note about this in the docs.

My previous suggestion should work, this kind of dependency between
fixtures is common and well supported. If it doesn't, it means I probably
didn't understand your problem completely, in which case I would ask to
post a more detailed pseudo-code which better conveys the problem.

Hope this helps,
Bruno.
