Mutation Testing That Understands Spring
ArcMutate optimizes PiTest for Spring Boot — correctly handling dependency injection, @MockBean, test contexts and framework-generated code.
Why Spring Applications Need Special Handling
Spring's dependency injection, proxies and test slices confuse naive mutation testing. Plain PiTest has no awareness of the framework, which means wasted analysis time and misleading results on Spring codebases.
Framework-aware analysis
Deep integration with Spring Boot, understanding framework patterns and optimizing mutation testing for Spring applications.
Correct @MockBean handling
Test contexts, slices and mocked beans are handled correctly, so your mutation score reflects real test quality.
Security mutation operators
Security-specific mutation operators for teams using Spring verify that your tests guard security-sensitive logic — catching security issues early.
Scales to real applications
Combine with incremental analysis and PR integration to run Spring mutation testing on every pull request.
Quick Start with Maven

Spring Mutation Testing FAQ
Does mutation testing work with Spring Boot?
Yes. ArcMutate extends PiTest with deep Spring Boot integration, correctly handling @MockBean, test contexts, dependency injection, proxies and framework-generated code.
What are security mutation operators?
Security-specific mutation operators verify that your tests would catch changes to security-sensitive logic such as authentication and authorization checks — helping banks and enterprises catch security issues early.
Will it slow down my build?
Run it incrementally: ArcMutate can mutate only the code changed in a pull request, and subsumption analysis removes redundant mutants. Teams typically see PR-scoped runs complete in minutes.
