The Shortest Feedback Loop Is Better

Short feedback loops, it's everywhere. There's no reason not to have a short of all feedback loop if you can. If the value you gain from decreasing the size of your feedback loop is worth the investment you need to do, that's something a discussion you can be making. It's also the same with TDD, like I said, this is where the kind of TDD also shines but you want to test in different ways. But again, shorter is better.
