Refactoring is now a common term in the developer’s vocabulary. However what most developers call refactoring is really hacking. Making a change to the code in the hope that it will work is somewhat analogous to smoking a cigarette whilst filling up your petrol tank. Both will inevitably end in tears. And this is where the dogma kicks in; it is not really refactoring unless you have a safety net of automated tests to verify that the state of the universe has not changed since you last updated that pesky connection string. A bad test is better than no test at all. I guess that leads on to my next topic…false positives and false negatives. But for now get testing and buy a diesel.
