SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill helps improve software quality by analyzing why mutation tests fail to detect certain code changes, leading to more robust and effective test suites.

Core Features & Use Cases

  • Surviving Mutant Analysis: Identifies and categorizes why mutants survive mutation testing (e.g., insufficient coverage, equivalent mutants, weak assertions).
  • Root Cause Identification: Pinpoints the exact reasons for test suite weaknesses.
  • Automated Test Improvement: Generates actionable recommendations and new test cases to kill surviving mutants.
  • Use Case: After running a mutation testing tool, you have a low mutation score. Use this Skill to analyze the surviving mutants, understand the gaps in your test suite, and get suggestions for new tests to improve the score and code coverage.

Quick Start

Use the behavioral-mutation-analyzer skill to analyze mutation testing results from the 'pitest-report.xml' file.

FAQPage Schema
How do I analyze surviving mutants from mutation testing to improve my test suite?▼

Mutation testing analysis processes surviving mutants to identify root causes of test suite weaknesses. It classifies survivors into categories like insufficient coverage, equivalent mutants, and weak assertions, producing actionable test enhancements and new test cases.

What causes surviving mutants in mutation testing and how do I fix them?▼

Surviving mutants in mutation testing are caused by insufficient coverage, equivalent mutants, or weak assertions. Analyzing mutation testing results identifies these root causes and generates targeted test cases to kill the surviving mutants.

How do I generate new test cases to kill surviving mutants from a pitest-report.xml file?▼

You can generate new test cases by analyzing mutation testing results from a pitest-report.xml file. The analysis automatically produces actionable test enhancements and new test cases targeting the identified test suite weaknesses.

Can I use mutation analysis to find weak assertions in my repository test suites?▼

Yes, mutation analysis evaluates repository code and test suites to pinpoint weak assertions. It processes mutation testing results to identify root causes of test suite weaknesses and automatically generates actionable test improvements.

What is the best way to improve a low mutation score after running a mutation testing tool?▼

The best way to improve a low mutation score is to analyze surviving mutants to understand gaps in your test suite. This analysis classifies survivors and generates actionable recommendations and new test cases to increase code coverage.
