By the time we extracted Scientist, the code we were refactoring had pretty good test coverage. But even the best test suite is an imperfect model of production. The first section of the README briefly mentions this: "Let's pretend you're changing the way you handle permissions in a large web app. Tests can help guide your refactoring, but you really want to compare the current and refactored behaviors under load." |
