Well, if __name__ is not '__main__' for some reason [1], the if 
condition won't match and the function won't be called. (In this case, 
unittest.main() also won't be called.)

So _if_ the function is called, it _is_ always '__main__' ;-)

[1] the only possible reason I can imagine is that something else 
    has a "import test-foo" or "from test-foo import bar" - and in those 
    cases setup_all_tests and unittest.main() of the imported module
    won't run
