This removes so much headache in the long run. Often by writing tests you discover something not considered before and that improves the product a lot and its stability. I have some projects that have been online for like 4 years now without reboot. They have very good coverage. I hate going through logs and debugging, and I almost never do it after committing to testing. Things just work.
