I recently dropped another leading mocking tool in favor of JustMock. I was never happy with the other tool’s syntax but I couldn’t find anything else on the market. I’ve found JustMock is a much more pleasant experience.
When isolating methods for testing gets difficult when trying to test against legacy code or databases, JustMock really starts to set itself apart. Its features such as MsCorlib, Sealed, Static, Private method and Entity Framework mocking make the seemingly untestable, testable.
I've used a series of mocking tools and I believe that the API for JustMock is the most mature that I've encountered so far. The highest praise that I can give a framework tool is to say that its semantics are readable enough that you don't think about them at all as you're reading the code, and this is true with JustMock.
