Magnum Specific Commandments

[M302] Change assertEqual(A is not None) by optimal assert like assertIsNotNone(A).
[M310] timeutils.utcnow() wrapper must be used instead of direct calls to datetime.datetime.utcnow() to make it easy to override its return value.
[M316] Change assertTrue(isinstance(A, B)) by optimal assert like assertIsInstance(A, B).
[M318] Change assertEqual(A, None) or assertEqual(None, A) by optimal assert like assertIsNone(A)
[M322] Method's default argument shouldn't be mutable.
[M323] Change assertEqual(True, A) or assertEqual(False, A) by optimal assert like assertTrue(A) or assertFalse(A)
[M336] Must use a dict comprehension instead of a dict constructor with a sequence of key-value pairs.
[M338] Use assertIn/NotIn(A, B) rather than assertEqual(A in B, True/False).
[M339] Don't use xrange()
