> Writing tests makes me a better programmer Writing bug free software without writing tests also makes you a better programmer. Practice helps, and practicing creating architectures that are easy to make correct without tests really makes you a better programmer. If you can't both do well with tests everywhere and do well without tests then you aren't a great software engineer. The reason is that first you create an architecture that is easy to make correct, then you add tests on top of that, and now you got something great, using tests as a crutch prevents you from ever reaching that stage.
