A little unittest refactoring * Add a class decorator to generate tests when using a unittest.TestCase base class * Add a TestCase subclass with setUp() and tearDown() that sets up module parameter parsing * Move test_safe_eval to use the class decorator and ModuleTestCase base class * Move testing of set_mode_if_different into its own file and separate some test methods out so we get better errors and more coverage in case of errors. * Naming convention for test cases doesn't need to duplicate information that's already in the file path.
