Mostly it was reporting, I think. With assertEquals(x,y), you get a
nice message showing the values of x and y. This is obviated by nose,
which can introspect to get the values. From the unittest
documentation:

  """These methods are used instead of the assert statement so the
test runner can accumulate all test results and produce a report."""
