Kill All Mutants! - Introduction to Mutation Testing

Discover the power of mutation testing in this 22-minute conference talk from JSConf Hawaii 2020. Explore how to assess the quality of your tests and code by introducing subtle alterations, or "mutants," into your functions. Learn how mutation testing reveals potential flaws in your codebase and test suite by examining which mutants survive the testing process. Gain insights into the benefits, drawbacks, and pitfalls of this technique, as well as its inner workings. Follow along with clear pseudocode examples and receive a list of mutation testing tools for popular programming languages, including JavaScript. Equip yourself with this powerful technique to ensure your tests are strict and your code is meaningful, ultimately improving the overall quality of your software development process.
