I agree with Robert's point, but for the record there are at least a
couple parts of the existing TestCase API that control how much data
is given, for example the longMessage and maxDiff attributes of
TestCase:

http://docs.python.org/3/library/unittest.html#unittest.TestCase.longMessage

So it is possible that there are valid use cases.
