Mocking library focusing on very explicit definition of the mocks' behaviour

Project description

DO NOT USE THIS LIBRARY: there is now a standard mocking library in Python. I will not fix anything in this library and I’m migrating my own projects to unittest.mock.

MockMockMock is a Python (2.7+ and 3.3+) mocking library focusing on very explicit definition of the mocks’ behaviour. It allows as-specific-as-needed unit-tests as well as more generic ones.

It’s licensed under the MIT license. It’s available on the Python package index, its documentation is hosted by Python and its source code is on GitHub.

Quick start

Install from PyPI:

$ pip install MockMockMock


>>> from MockMockMock import *

Write some code to test:

>>> def f(source):
...   return source.get(42) * 2


>>> mocks = Engine()
>>> mock = mocks.create("mocks")


>>> mock.expect.get(42).and_return(12)


>>> assert f(mock.object) == 24

Verify all expected calls have been done:

>>> mocks.tearDown()
