Test Fixing

Run your test suite, group failures by root cause, and fix them systematically — turning red builds green with minimal, targeted changes.

Features

• Smart Error Grouping — Clusters test failures by shared root cause to avoid duplicate fixes
• Auto-Fix Engine — Generates targeted code patches for common failure patterns
• Import Resolution — Fixes broken imports, missing modules, and path resolution errors
• Mock Repair — Updates stale mocks and fixtures to match current API contracts
• Iterative Loop — Runs test-fix-rerun cycles until all tests pass or manual intervention is needed

Quick Start

claude skill install test-fixing

Usage

# Run tests and fix all failures
/test-fixing

# Fix failures in a specific test file
/test-fixing --file src/components/Button.test.tsx

How It Works

Executes your test suite, captures failure output, and groups errors by common root causes (broken imports, API changes, stale snapshots, etc.). Generates minimal fixes for each group and re-runs affected tests to verify. Continues the fix-verify loop until all tests pass or reports remaining issues that need manual attention.

Compatibility

Works with Claude Code, Codex, Gemini CLI, Cursor, Windsurf, and Aider.
