Testing in production is essential if you want to test software as rigorously as possible. Why? While testing early in the pipeline (i.e., shift-left testing) is necessary and highly encouraged, it’s simply not enough on its own. Companies practicing agile testing methodologies and building a disposable infrastructure are ready to perform testing in production, which is sometimes called shift-right testing. By testing in production, you build another level of confidence in releases after performing various checks in a live production environment. Testing in production allows the company to see how an application reacts to newly pushed code changes in the wild. It should become a significant component of your future application quality strategy going forward. Below, I explain why it’s important to test in production, then offer tips for developing a shift-right testing strategy. Session Takeaways: - What Are the Advantages of Testing in Production? - What Are the Risks? - Potential Testing in Production Tactics
