All:

I would like to use a nice unit testing framework for my current project. I seem to use quite a significant number of bash scripts (not to mention that many of those were developed with the help of LinuxQuestions community! :P ) and I would like to know whether there is any way by which I could test them like any xUnit framework.

I did some preliminary search on this and I got ShUnit2. I tried gathering some tutorials on this but didn't get any.

It would be great if I could have some pointers or help on this framework. Also, are there any other unit testing frameworks better than the ShUnit2?

Thanks in advance!

Have a look at TET (Test Enviroment Toolkit). It is the used by many standards and specification testsuites. using TCL and Expect.
