Test Coverage Analyzer
Analyze test coverage metrics, identify untested code paths, and generate comprehensive coverage reports.
Capabilities
- Line coverage - Which lines are executed
- Branch coverage - Which branches taken
- Function coverage - Which functions called
- Statement coverage - Which statements executed
- Uncovered code identification - Find gaps
- Coverage trends - Track over time
- Threshold enforcement - Minimum coverage requirements
Usage
/analyze-coverage # Analyze current coverage
/analyze-coverage --threshold 80 # Enforce 80% minimum
/analyze-coverage --detailed # Detailed report
/cov # Shortcut

Code Coverage Report
====================
Overall Coverage: 78.5%
By File:
src/utils/validator.js 95.2%
src/api/users.js 82.1%
src/api/products.js 68.4% ️
src/services/payment.js 45.7%
By Type:
Lines: 78.5% (1,571 / 2,000)
Branches: 72.3% (289 / 400)
Functions: 85.1% (85 / 100)
Statements: 78.2% (1,563 / 2,000)
Uncovered Lines:
src/api/products.js:45-52 (error handling)
src/api/products.js:78-82 (edge case)
src/services/payment.js:23-67 (refund logic)
Recommendations:
1. Add tests for payment service refund logic
2. Test error handling in products API
3. Cover edge cases in product filtering
Best Practices
- Aim for 80%+ coverage
- 100% coverage != bug-free
- Focus on critical paths
- Cover edge cases
- Test error handling
- Track coverage trends
