mutflow - Mutation Testing inside test-suite. Compile once, catch gaps

mutflow is a mutation testing tool for Kotlin, implemented as a K2 compiler plugin. It injects all mutations at compile time and activates them one-by-one during your normal test run. Compile once, get results fast. It integrates with JUnit and Gradle with minimal setup. You could test it yourself within 5 minutes. Built for teams that want mutation testing without the overhead.
