There is a story circulating around the world of software development that comes in many different flavors. Here’s a common version:
(A) Thanks to modern development methods, software quality is drastically improving.
(B) Thanks to the Facebook effect, customers are willing to live with software that is much lower quality.
(C) Thanks to DevOps, we notice problems in production very quickly and can “roll back” before most customers ever have a problem.
Therefore, we do not need software testers.
