Ooooh! I like that! Except that instead of a scripting updating __all__, 
it's a unit test that fails.

I don't know if this should go into unittest or test.support.

https://docs.python.org/3/library/test.html#module-test.support

Off the top of my head, something like:

class TestAll(unittest.CheckAll):
    module = name_of_module_to_check
    skip = [names, to, skip]

which scans the source of module, extracts all the public names, and 
fails if any of them (other than those listed in skip) are missing from 
__all__. If the source is unavailable, the test is skipped rather than 
passing.
