Built-in mocking framework for MXUnit frustrating and difficult to use
I'm fairly new to Coldfusion; at my new position, we're using MXUnit for unit testing our service library, but so far we're not mocking out the database (so we're testing against live data). I want to introduce better practices for testing the middle layers, but after spending a day playing with MightyMock, the built-in mocking framework for MXUnit 2.x, I found it frustrating and difficult to use as well as limited in features.
Is there a good book or tutorial? Or are people mostly using a third-party library for this? If so, what ones should I investigate?
Our company eventually went with MockBox, which has somewhat better documentation.
