UnitTest Framework - Unittest2

unittest2 is a backport of additional features added to the Python testing framework in Python 2.7 and onwards. It is tested to run on Python 2.6, 2.7, and 3.*. Latest version can be downloaded from https://pypi.python.org/pypi/unittest2

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

Classes in unittest2 derive from the appropriate 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. In case you intend to implement new features, subclass your testcase from unittest2.TestCase instead of unittest.TestCase

The following are the new features of unittest2 −

• addCleanups for better resource management

• Contains many new assert methods

• assertRaises as context manager, with access to the exception afterwards

• Has module level fixtures such as setUpModule and tearDownModule

• Includes load_tests protocol for loading tests from modules or packages

• startTestRun and stopTestRun methods on TestResult

In Python 2.7, you invoke the unittest command line features (including test discover) with python -m unittest <args>.

Instead, unittest2 comes with a script unit2.

unit2 discover
unit2 -v test_module
