Stryker

Mutation testing for JavaScript, C# and Scala

About Stryker

A mutation testing framework that introduces small changes to code and checks whether tests catch them, revealing weak tests and improving confidence in test suite quality across languages. Because the code is openly available, it can be audited, extended and run on private infrastructure, which makes it attractive to teams with privacy or compliance needs. It is commonly adopted through containers or packages, evaluated against commercial alternatives and kept because it solves a focused problem reliably at scale.
