Maintaining any kind of test suite becomes very important when you application is growing at a fast pace and you have to keep an check on what’s done on every release so as to provide a bug free product. Most of the test cases after your product launch includes the regressions tests. Therefore, well-designed and maintained suits becomes very fruitful in time of need. Irrespective of the tool, you are using either paid or open source.
There are many possible ways for managing the regression test suite depending upon which tool and technology you are using. However, the core structure would remain same and the regression suits can be divided into following:
P1 being highly critical, followed by P2 and P3.
You can continue to create more based on the number of critical areas though 3-4 regressions suits are sufficient for any major application.
