It is easy to let your regression suite get out of hand. We tend to throw every test case we create in the regression suite. It is a test case dump yard for everything test we create that isn’t in the smoke test. We want to make sure everything works as expected before each release. When we do this long enough, we end up with thousands of test cases.
Before you know it, your regression suite is a forest, when you only need a few trees. There has to be a better way.
