ArcMutate is CDG’s industrial quality mutation testing tool for Java and Kotlin. It replaces Jester as the world’s most popular open source mutation testing system for the JVM because:

  • it fails fast
  • its parallelised
  • it creates mutants in memory via byte code manipulation, meaning that it has no generation costs
