Do you ever wonder why there is an extra "False" printed at the end of each run for unit tests?

C:\Code\sample>ipy UnitTests.py
.....
----------------------------------------------------------------------
Ran 5 tests in 0.395s

OK
False

It looks like there is an exit statement buried inside the unit test framework. We can eliminate the problem pretty easily with the addition of a try/except around the unit test execution. Here is the code to put at the end of your unit test script:

if __name__ == '__main__':
    try:
        unittest.main()
    except SystemExit:
        pass

This catches and eats the SystemExit exception, and runs without printing the "False" at the end of the execution:

C:\Code\sample>ipy UnitTests.py
.....
----------------------------------------------------------------------
Ran 5 tests in 0.387s

OK

cheers!
