mock A Python Mocking and Patching Library for Testing There are already several Python mocking libraries available, so why another one? Most mocking libraries follow the 'record -> replay' pattern of mocking. I prefer the 'action -> assertion' pattern, which is more readable and intuitive particularly when working with the Python `unittest module <http://docs.python.org/lib/module-unittest.html>`_. For a discussion of the merits of the two approaches, see `Mocking, Patching, Stubbing: all that Stuff <http://www.voidspace.org.uk/python/articles/mocking.shtml>`_. ``mock`` provides a core ``Mock`` class that is intended to reduce the need to create a host of trivial stubs throughout your test suite. After performing an action, you can make assertions about which methods / attributes were used and arguments they were called with. You can also specify return values and set specific attributes in the normal way. It also provides a ``patch`` decorator that handles patching module and class level attributes within the scope of a test, along with ``sentinel`` for creating unique objects. http://www.voidspace.org.uk/downloads/mock-0.6.0.zip Michael Foord 3c028684c0036c8ed14e2355d0dae4d1add4da2c 0.6.0
