We have a set of test cases for Integration testing. Now we plan to automate regression test cases using WInRunner. I would like to know what are the guidelines to identify the Regression Test Cases. I can see two approaches to this Approach One-To identify test cases which hit the core functionality of each component of the application. Approach Two-Select only those test cases for which the code is going to be changed in the next phase. Which approach would the Guru recommend?
