What is your single favorite mocking library for Python?

minimock which uses doctest – Conductivity 25/1, 2013 at 9:40

"Mockito is a mocking framework that tastes really good. It lets you write beautiful tests with clean & simple API. Mockito doesn't give you hangover because the tests are very readable and they produce clean verification errors." code.google.com/p/mockito – King 21/3, 2014 at 12:55

I've only used one, but I've had good results with Michael Foord's Mock: http://www.voidspace.org.uk/python/mock/.

Michael's introduction says it better than I could:

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.

...

It also provides utility functions / objects to assist with testing, particularly monkey patching.

mock is now part of the Python standard library, available as unittest.mock in Python 3.3 onwards. – Overcoat 9/5, 2013 at 10:11

Do NOT use backported mock with Python 2.x! It is last updated in 2012, riddled with bugs (see the issues on google code!). Stay away. – Passer 19/3, 2015 at 22:22

I find it poorly documented, in a very non-intuitive way. – Tower 26/1, 2012 at 19:22

Mocker from Gustavo Niemeyer.

It's not perfect, but it is very powerful and flexible.

Mocker is extensively covered in Daniel Arbuckle's "Python Testing: Beginner's Guide" (Packt). – Byword 24/1, 2011 at 5:50

I'm the author for mocktest. I think it's pretty fully featured and easy to use, but I might be biased:

I've used pMock in the past, and didn't mind it, it had pretty decent docs too. However, Foord's Mock as mentioned above is also nice.

That's what the pMock's author says about pMokc: "Just to note that pMock is no longer in development (really must update the web page), actually it was more an experiment I finished playing with about four years ago and assumed the "alpha" designation would scare people away."
