Summary

ArcMutate adds mutation testing to Java, Kotlin, and Android software projects, extending PiTest to help teams identify bugs that existing tests may miss. It can run mutation analysis as part of pull request workflows on GitHub, GitLab, Bitbucket, and Azure DevOps. Incremental analysis limits mutation work to new or changed code and is described as 10x faster analysis. Subsumption analysis removes redundant mutants, and the tool includes mutation operators beyond standard PiTest. ArcMutate is available through Maven Central and supports Maven and Gradle setup. The maker says customer code remains within the customer's network and can be analyzed in air-gapped environments. Android support is beta: instrumented tests are unsupported, and analysis is enabled for tests running in the same JVM as the code under test. There is a free trial with no credit card required, but no duration is stated. The Open Source plan is free for open-source projects; paid plans start at $8/user/mo.

Who it is for

ArcMutate suits teams testing Java or Kotlin projects, including software work in automotive safety, banking, and healthcare. Android teams should account for its beta status and test limitations.

What is good

Pull request workflows cover four listed providers
Incremental analysis targets changed code
Supports Maven and Gradle setup
Air-gapped use is supported

What to know first

Android support is beta
Instrumented Android tests are unsupported

Verdict

ArcMutate adds mutation analysis to existing development workflows, with incremental analysis and extended operators. Check its Android constraints and plan details, including the per-user price, before choosing it.
