FailUnless Should Not Be Used In Python Unit Tests To Test Identity

In unit test, use assertEqual, so we see the difference in traceback

Good Example:

self.assertEqual(self.getSimulationState(), "draft")
self.assertNotEqual(self.getSimulationState(), "delivered")

Bad Example:

self.failUnless(self.getSimulationState() == "draft")
self.failUnless(self.getSimulationState() != "delivered")
