# 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
|
||
|
||
```bash
|
||
/analyze-coverage # Analyze current coverage
|
||
/analyze-coverage --threshold 80 # Enforce 80% minimum
|
||
/analyze-coverage --detailed # Detailed report
|
||
/cov # Shortcut
|
||
```
|
||
|
||
## Report Format

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
