By default unittest.main() scans the __main__ module for TestCases.
Though you could use it from an interactive interpreter
>>> import unittest
>>> unittest.main("PyMC", argv=["yadda", "-v"])
test_alpha (PyMC.Test) ... ok
test_beta (PyMC.Test) ... ok
----------------------------------------------------------------------
Ran 2 tests in 0.000s
OK
$ # Oops
without countermeasures unittest.main() will exit that too after completion.
The normal usage (the only one I know) is to put it inside the test script:
# your testcases
if __name__ == "__main__":
unittest.main()
and run that from the shell:
$ python PyMC.py -v
test_alpha (__main__.Test) ... ok
test_beta (__main__.Test) ... ok
----------------------------------------------------------------------
Ran 2 tests in 0.001s
OK
