Hey,
Thanks all of you guys! I get that Test::Unit is not a good choice. From all various package names I see posted here, please show me a small working example where I have a test suite which has 2 or three test cases and a test runner and reporting tool. Also I need to know, are there different extensions formats for any of the above (like .t or specifically having .lib folder to store all testsuite files etc). This will exactly solve my problem of visualizing what you all are talking about.
Thanks for all the responses!
