----------
Mutation Testing in the Age of AI-Generated Code
speaker: Dmitrii Suroviagin, Lead Software Engineer @EPAMMost teams track code coverage. Some even celebrate 100%.
But coverage only tells you which lines were executed, not whether your tests would catch a real bug.Mutation testing flips the perspective. Instead of measuring how much code runs, it intentionally introduces small faults into your code and checks whether your tests detect them. If they don’t, your test suite may be weaker than it looks.
In this talk, I’ll start with a short, practical introduction to mutation testing and why it matters. Then we’ll look at how to apply it in JavaScript and TypeScript projects using modern tooling. I’ll share real-world lessons from running mutation testing in production libraries — including performance challenges, CI strategies, and how to avoid turning it into an expensive vanity metric.
Finally, we’ll discuss why mutation testing becomes even more important in the era of AI-assisted development. When AI agents generate code and tests for us, how do we know they are actually robust? Mutation testing might be the missing feedback loop.
