Backport of new unittest features for Python 2.7 to Python 2.4+
unittest2 is a backport of the new features added to the unittest testing framework in Python 2.7. It is tested to run 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 infrastructure 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.
