<div>Have you ever wondered: "who's testing the tests"? Of course, tests are only valuable if they catch bugs, but how would one validate that? Well, let me tell you about mutation testing! Mutation testing is the act of testing your test verifying that they catch bugs. Of course, you can do this manually inserting bugs and running the tests, but a mutation testing framework can do this for you! Join me and learn the basics of mutation testing and how to use StrykerJS, the mutation testing framework for JavaScript or TypeScript.At the end of this talk, you'll be the one that is testing your tests, and it won't even cost you much time!</div> <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
