The new features in unittest for Python 2.7 backported to Python 2.4+.
Project description
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.
New features include:
addCleanups - better resource management
many new assert methods including better defaults for comparing lists, sets, dicts unicode strings etc and the ability to specify new default methods for comparing specific types
assertRaises as context manager, with access to the exception afterwards
test discovery and new command line options
test skipping and expected failures
load_tests protocol for loading tests from modules or packages
startTestRun and stopTestRun methods on TestResult
various other API improvements and fixes
Until I write proper documentation, the best information on all the new features is the development version of the Python documentation for Python 2.7:
Look for notes about features added or changed in Python 2.7.
