You are in good company here. The TestUnit framework comes with the standard
Ruby install and is amazingly easy to use. For details see:

I will recommend FlexMock for this purpose. You can find FlexMock at:
http://onestepback.org/software/flexmock/

Take a look at the article "Mock Turtle Soup":

Hope that helps. If you can show snippets of your code,
I am sure fellow Rubyists will help more specifically.
