Language coverage: PIT is designed for Java and the JVM; Kotlin support is provided through an ArcMutate plugin.pitest.org · 30 Sept 2026
Test selection: PIT uses line coverage, test execution speed, and test naming conventions to select and prioritize tests for mutations.pitest.org · 30 Sept 2026
Build integrations: PIT can be launched from the command line, Ant, or Maven, with third-party integrations for Gradle, Eclipse, and IntelliJ.pitest.org · 30 Sept 2026

JUnit 5 limit: JUnit 5 is not supported out of the box, though the FAQ links to a plugin for it.pitest.org · 30 Sept 2026
Runtime limitation: Mutation testing can take a long time depending on codebase size and test suite speed; PIT recommends focusing analysis on changed code.pitest.org · 30 Sept 2026
