QA in Production: The tests we never wrote and the production monitoring we use instead

Download to read offline

Things always go wrong in production, but this doesn’t have to be a bad thing. It’s an opportunity to learn about your system and the real world with which it interacts. Rouan will show you how to build a set of feedback mechanisms that help you find out about issues as they happen and ship fixes quickly. Using real examples, he’ll walk you through how they use metrics, logging, auditing and alerting to support tes.com and move fast. He’ll show you which tests to throw away and what to put in their place. He’ll guide you to finding the right balance of pre-production and production quality practices, so that you can gain a more realistic and holistic understanding of the quality of your system.
