Mutation Testing

PythonJavaScriptTypeScriptJavaC#Go

Find bugs and weaknesses in your code changes by intelligently injecting faults into your PR diff. Our AI-powered mutation testing tool helps you identify potential issues specifically in your changes before they reach production.

How Mutation Testing Works

Git RepositoryPR Diff AnalysisLLMGenerateTargeted FaultsApply Faultsto ChangesRun Testson Modified CodeVulnerability ReportIdentifyWeak AreasGenerate FixSuggestionsLLMImprovedCode Quality

1. Our system analyzes your PR diff to identify only the code you've changed.

2. AI generates targeted faults specifically for your changes to find potential bugs.

3. Tests run against your modified code to see if they catch the injected faults.

4. A vulnerability report shows where your changes might have weaknesses or bugs.

5. Our AI suggests specific improvements to strengthen your code before it's merged.
