When we talk about testing, we not only need to understand why we are testing it, but more importantly, the how do we test it. The “why” is fairly straight forward, as we want to determine if it is still functioning properly and that we can reuse it. The how to test it might not be as clear, and there are multiple methods of how to test, and sometimes opinions on how to test that are not always accurate.
