That's fine. It's a good book. That doesn't mean the analogy works in every situation. I happen to think it doesn't in this one. Dr. Hipp is a great coder. Telling him to "develop better" from that analogy just falls apart. Tests are there for a reason and Dr. Hipp uses them to great effect on the quality of SQLite.

Yeah I agree. Actually the whole point of the original comment was about SQLite's robustness as the result of multiple development practices they use(including testing of course), but testing coverage can't lead to success itself. That's it)
