  The unittest.TestCase.assertEqual() now displays the differences in lists,
  tuples, dicts and sets on failure.

  Many new handy type and comparison specific assert* methods have been added
  that fail with error messages actually useful for debugging.  Contributed in
  by Google and completed with help from mfoord and GvR at PyCon 2009 sprints.

  Discussion lives in http://bugs.python.org/issue2578.

  Rename the actual method definitions to the official assertFoo names.

  Adds unittests to make sure the old fail* names continue to work now
  and adds a comment that they are pending deprecation.

  Also adds a test to confirm that the plural Equals method variants
  continue to exist even though we're unlikely to deprecate those.

  Better exception messages for unittest assert methods.

  - unittest.assertNotEqual() now uses the inequality operator (!=) instead
    of the equality operator.

  - Default assertTrue and assertFalse messages are now useful.

  - TestCase has a longMessage attribute. This defaults to False, but if set to True
    useful error messages are shown in addition to explicit messages passed to assert methods.

  Store the functions in the _type_equality_funcs as wrapped objects that are deep copyable.

  This allows for the deep copying of TestCase instances.
