 ## Working on the Exercises
 
 We welcome both improvements to the existing exercises and new exercises.

 - We use `unittest` (Python Standard Library) and no 3rd-party-framework.
 - We use the parameter order `self.assertEqual(actual, expected)` ([#440](https://github.com/exercism/python/issues/440)).
 - We use context managers (`with self.assertRaises(\<exception type\>):`) for testing for exceptions ([#477](https://github.com/exercism/python/issues/477)).
+- We use an established utility method to confirm that expected exceptions contain a non-empty message. This method must be included for any test class with an exception-based test case ([#1080](https://github.com/exercism/python/issues/1080#issuecomment-442068539)).
 - We use `assertIs(actual, True)` and `assertIs(actual, False)` rather than `assertTrue(actual)` or `assertFalse(actual)` ([#419](https://github.com/exercism/python/pull/419)).
 - We use a comment string in the test file to reference the version of the exercise's `canonical-data.json` that tests were adapted from (wording can be found in: [#784](https://github.com/exercism/python/issues/784)).
 
 
 ### Testing
 
-All exercises must be compatible with Python versions 2.7 and 3.3 upwards.
