How do you know your feature is working perfectly in production? What do you do when your staging test results do not reflect current production behavior? In order to test proactively as opposed to reactively, try testing in production! You will have an increased accuracy of test results, and you will have higher confidence before releases. You will learn about feature flagging, canary releases, data cleanup, and strategies to mitigate risk. At the end of the day, we don't care if your features work in staging, we care if they work in production.
