running a PyUnit TestSuite

One way is to use the defaultTest argument to unittest.main:

    #!/usr/bin/env python
    import unittest

    class TestCase1(unittest.TestCase):
        def testFoo(self):
            self.assert_(1)

    class TestCase2(unittest.TestCase):
        def testBar(self):
            self.assert_(0)

    def suite():
        loader = unittest.TestLoader()
        s = unittest.TestSuite()
        s.addTest(loader.loadTestsFromTestCase(TestCase2))
        s.addTest(loader.loadTestsFromTestCase(TestCase1))
        return s

    if __name__ == '__main__':
        unittest.main(defaultTest='suite')

But I do wonder why your tests need a given execution order.  This
is contrary to the doctrine of unit tests, which holds that each
test should be independent.
