TestFixtures is a collection of helpers and mock objects that are useful when writing unit tests or doc tests.
If you're wondering why "yet another mock object library", testing is often described as an art form and as such some styles of library will suite some people while others will suite other styles. This library was extracted from common test fixtures the author found himself repeating from package to packages and so decided to extract them into their own library and give them some tests of their own!
The available helpers and mock objects are listed on the PyPI page
