My test file is basically:

class Test(unittest.TestCase):
    def testOk():
        pass

if __name__ == "__main__":
    expensiveSetup()
    try:
        unittest.main()
    finally:
        cleanUp()

However, I do wish to run my test through Netbeans testing tools, and to do that I need unittests that don't rely on an environment setup done in main. Looking at http://stackoverflow.com/questions/402483/caching-result-of-setup-using-python-unittest - it recommends using Nose. However, I don't think Netbeans supports this. I didn't find any information indicating that it does. Additionally, I am the only one here actually writing tests, so I don't want to introduce additional dependencies for the other 2 developers unless they are needed.

How can I do the setup and cleanup once for all the tests in my TestSuite?

The expensive setup here is creating some files with dummy data, as well as setting up and tearing down a simple xml-rpc server. I also have 2 test classes, one testing locally and one testing all methods over xml-rpc.
