Have you ever wondered how effective your unit tests are? There’s an easy way to find out: use mutation testing.
Unit testing is important. It helps us catch common mistakes and keep our code base maintainable. But writing them is an everyday challenge. Measuring the code coverage can help us a great deal, but what does this metric actually tell us? Join this session and learn how mutation testing can measure the actual effectiveness of your unit tests.
“But how?” you might wonder. Meet Stryker - the open source mutation testing framework for JavaScript and friends. We’ve been developing it for over 2 years now and support for most JavaScript use cases. See how Stryker can also improve your testing life with a live demo.
