We could have this, similar to the testing framework we have for the bears. Although this is quite different from that since this involves a lot of mocking and other stuff but that would be a good learning base before implementing this. I think this alone could be a potential GSoC project.

@abhishalya https://github.com/coala/corobo/blob/master/tests/corobo_test_case.py There is always room for improvement. It'd be awesome if you or someone else can pitch in new ideas so that we can improve it further.
