> It's just extremely satisfying to have almost complete confidence that the code will work in production on the first try. I agree that TDD has enormous benefits when used with discipline, but remember to temper your expectations as to the actual purpose of tests. The fact that your tests pass doesn’t mean your app is bug free—it is only free of the bugs you were able to test for. There’s a concise but somewhat counterintuitive quote from Dijkstra that summarizes what tests help you uncover: ”Program testing can be used to show the presence of bugs, but never to show their absence!” https://en.wikiquote.org/wiki/Edsger_W._Dijkstra#1970s https://en.wikiquote.org/wiki/Edsger_W._Dijkstra#1970s
