My probe about Test Driven Development

Coding could be easy, but coding correctly is very hard. The problem I faced recently is:  every task assigned to me have to pass the most strict tests from QA. It becomes more and more important to adapt the method of test driven development. I don't have too much experience of using this method. If I made some mistake in my blog, let me know.

So, What shall I do? Here is the solution, replacing .  and regexp_like(DR.RESET_TYPE,NV...
