Making Mutants Work for You

Explore mutation testing, a powerful technique for improving test quality, in this 41-minute conference talk from GOTO Copenhagen 2019. Learn how PiTest, an open-source tool, has made mutation testing more accessible to the Java community. Discover the true value of mutation testing beyond "more than 100% code coverage" and gain insights into its practical applications. Understand how deliberately introducing bugs into your code can help evaluate and enhance your test suite's effectiveness. Dive into the history of this once-obscure development technique dating back to the 1970s and see how it has evolved to become a valuable asset for modern developers. Gain knowledge from Henry Coles, the creator of PiTest, as he shares his expertise on leveraging mutation testing to improve developer productivity and overall code quality.
