Thanks a lot for the reply.. It cleared a lot of questions I had, cuz in the process of writing tests for my application i found that more than 60% of my tests required some kind of mocking to do some kind of unit testing. Then I was wondering if I was missing something in the way that I am using PureMVC since it gives me a code coverage of around 1/3 only. Anyway I think I should be looking at something like http://riatest.com/
for testing the entire applications data flow and the cascade of actions.
Thanks again and Keep up the great work.
