You'll note that the problem shows up in the getpass module, which does have tests, but which does not have a test that discovers this.  That's because writing tests that *use* these functions is not really practical :)

Someone could open an issue about testing for the functions that are supposed to be available.  There could also be another issue for gettpass to test for the availability of the functions it actually uses.

Steve, looks like you forgot to close the issue?  Or were you waiting for agreement about the tests?
