Description:

unittest2 is a backport of the new features added to the unittest
testing framework in Python 2.7. It has been tested to on Python 2.4 -
2.6.

To use unittest2 instead of unittest simply replace ``import
unittest`` with ``import unittest2``.

Classes in unittest2 derive from the equivalent classes in unittest,
so it should be possible to use the unittest2 test running infra-
structure without having to switch all your tests to using unittest2
immediately. Similarly, you can use the new assert methods on
``unittest2.TestCase`` with the standard unittest test running
infrastructure. Not all of the new features in unittest2 will work
with the standard unittest test loaders and runners, however.
