SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Mutation testing helps you quantify the effectiveness of your test suite by introducing small, controlled faults into the codebase and checking whether tests detect them.

Core Features & Use Cases

  • Cross-stack mutation support for JavaScript/TypeScript, PHP, Go, and Python projects.
  • Generates a survivors.json handoff with detailed mutation results and a Markdown executive report.
  • Guides incremental vs full scans, concurrency, and threshold-based quality gates for CI.

Quick Start

Run mutation testing on the current project to measure test effectiveness across supported stacks.

FAQPage Schema
What is mutation testing and how does it measure test suite effectiveness?

Mutation testing supports JavaScript, TypeScript, PHP, Go, and Python projects. You can perform mutation testing across these multiple tech stacks to measure test effectiveness by evaluating framework availability and scope configuration for each environment.

How do I run mutation testing on my project to measure test effectiveness?

After mutation testing completes, you receive a survivors JSON handoff containing detailed mutation results and a Markdown executive report. These outputs document surviving mutants and provide an overview of your test suite's effectiveness for quality gate evaluation.

Can I use mutation testing with threshold-based quality gates for CI pipelines?

This mutation testing approach handles incremental or full project scans across supported stacks. Incremental scans evaluate only changed source files and tests, while full project scans apply controlled faults across the entire codebase to measure test effectiveness.

Does mutation testing work with JavaScript, TypeScript, PHP, Go, and Python projects?

This mutation testing approach handles incremental or full project scans across supported stacks. Incremental scans evaluate only changed source files and tests, while full project scans apply controlled faults across the entire codebase to measure test effectiveness.

How do I configure mutation testing for incremental versus full project scans?

After mutation testing completes, you receive a survivors JSON handoff containing detailed mutation results and a Markdown executive report. These outputs document surviving mutants and provide an overview of your test suite's effectiveness for quality gate evaluation.

What outputs do I get from mutation testing to track surviving mutants?

Yes, mutation testing can be configured with threshold-based quality gates for CI pipelines. It guides incremental versus full scans and concurrency settings to integrate test effectiveness measurement into your continuous integration workflow.
