Instead of explicitly enumerate test classes for run_unittest() use the unittest ability to discover tests. This also makes these tests discoverable and runnable with unittest. load_tests() can be used for dynamic generating tests and adding doctests. setUpModule(), tearDownModule() and addModuleCleanup() can be used for running code before and after all module tests.
