Coverage metrics. Regression safety. The QA team&rsquo;s peace of mind. But anyone who has worked seriously with TDD, or spent time with practitioners like Emily Bache, knows that tests are almost a side effect. The real output is <em>understanding</em>.</p> <p>TDD, done well, is a method for thinking your way through a problem one small step at a time. You don&rsquo;t start with a complete picture of the solution. You start with the smallest possible question: <em>what is the simplest behavior this code should exhibit?</em> You write a test for that. You make it pass. And in the process of making it pass, you learn something — about the problem, about your assumptions, about the design that is quietly trying to emerge.</p>
