Uncle Bob is insufferable and thinks that anything less than 100% testing and your code doesn't work. > The more tests you have, the more evidence you build up that the theory that the software is incorrect in some way may be wrong. Or you could actually use the software. You can have 100% unit tests passing and a completely broken integration.
