The purpose of the project: allow developers to easily compare mocking frameworks available for .NET, and make an informed decision when picking one up.

It provides a unified set of tests to showcase Moq, NMock2, Rhino Mocks, Isolator and Moles.

Each test is written against every framework so you can easily compare syntax of the frameworks and implications of using any of them. For educational purposes, source code of the frameworks is provided (apart from the Isolator which is a paid one - but you can download a 21 day trial - and Stubs framework which is free but not open source).

You may want to read the readme before you start exploring the project.
