In some unit tests instead of self.fail(msg) statements
self.assertTrue(False, msg) were used, which might be ambiguous.
Using assertTrue(False, msg) gives the following message on fail:
File "C:\Python361\lib\unittest\case.py", line 678, in assertTrue
raise self.failureException(msg)
AssertionError: False is not true : msg
'False is not true' message implies that unit test failed (as the
result is False while we asserted True).
Replaced with self.fail(msg) is less ambiguous and more readable.
File "C:\Python361\lib\unittest\case.py", line 666, in fail
raise self.failureException(msg)
AssertionError: msg
TrivialFix
