We're excited to announce StrykerJS 6.2. Of course, this release comes with some bug fixes, but in this article, we want to focus on a popular new feature: incremental mutation testing.
Incremental mutation testing is ideal for Continuous Integration (CI) scenarios or if you want a faster feedback cycle locally. Indeed, many users seem to be interested in this since it was our most upvoted issue ever.
While in 'incremental mode', StrykerJS will track the changes you make to your code and tests and only runs mutation testing on the changed code; while still providing a full mutation testing report at the end!
