A while ago, I had the idea of always giving your customers a specially instrumented version of your product. The application would know what lines of code had been executed during your testing phase, and whenever the user ran a bit of code which hadn’t been tested pre-release, a dialog box would popup saying “Hey, you’re running code which we didn’t bother to test!”. How would you feel about doing that for your application?

Anyway, I stumbled across Guantanamo today which takes that one step further. It runs your unit tests, find any lines of code which haven’t been executed during the tests *and deletes them* from your source code. If they’re not being test, they’re not going allowed to exist. Heh, how cool is that?
