Quality Engineering in the Age of AI

AI generates code faster than ever, and it has made testing more important than ever. Vibe-coded features ship without contracts, without coverage, without any system-level view of what breaks when something changes. A professional QA engineer is the person who builds the infrastructure that tells you whether the code actually does what it's supposed to do, at scale, across environments, and without regressions eating your next sprint.

Current AI testing tools, while promising, fail to deliver scalable results that matter when your webapp needs to interact with human users. It has become apparent now more than ever that human eyes, and human designed tests must be in the loop.
