| **Lines** | 84% | ${thresholds.lines}% | ✅ Pass |
## Overall Result
❌ **Coverage validation FAILED** due to low branch coverage.
## Detailed Analysis
### Statements Coverage: ✅ PASS
- Current: 85%
- Required: ${thresholds.statements}%
- **Status**: Exceeds threshold by 5%
### Branch Coverage: ❌ FAIL
- Current: 78%
- Required: ${thresholds.branches}%
- **Gap**: -2% below threshold

- Review conditional statements in auth module
- Add tests for error handling paths
- Test edge cases in validation logic
2. **Maintain Good Practices**
- Continue comprehensive function testing
- Keep statement coverage above 85%
- Regular line coverage monitoring
## Files Needing Attention
- \`src/auth/authentication.ts\` - 65% branch coverage
- \`src/validation/user-validator.ts\` - 70% branch coverage
- \`src/payment/payment-processor.ts\` - 72% branch coverage

## Performance Issues Identified
### 1. Payment Processing Bottleneck
- **Impact**: High latency on payment endpoints
- **Cause**: External payment gateway timeout
- **Recommendation**: Implement circuit breaker pattern
### 2. Database Query Optimization
- **Impact**: Slow dashboard loading
- **Cause**: N+1 query problem
- **Recommendation**: Implement query batching
### 3. Memory Leak in Session Management
- **Impact**: Gradual memory increase
- **Cause**: Sessions not properly cleaned up
- **Recommendation**: Implement automatic session cleanup
## Load Testing Scenarios
### Scenario 1: Normal Load
- **Users**: 50 concurrent
- **Duration**: 10 minutes
- **Result**: ✅ All metrics within target
### Scenario 2: Peak Load
- **Users**: 100 concurrent
- **Duration**: 5 minutes
- **Result**: ✅ Acceptable performance with minor degradation
### Scenario 3: Stress Test
- **Users**: 200 concurrent
- **Duration**: 2 minutes
- **Result**: ⚠️ Response times increased, but system remained stable
## Recommendations
### Immediate Actions (High Priority)
1. **Fix Payment Gateway Integration**
- Implement timeout handling
- Add retry mechanism
- Set up monitoring alerts
2. **Optimize Database Queries**
- Review and optimize slow queries
- Implement query caching
- Add database indexing
### Medium-Term Improvements
3. **Implement Caching Strategy**
- Redis for session data
- CDN for static assets
- Application-level caching for frequently accessed data
4. **Scale Infrastructure**
- Consider horizontal scaling for web servers
- Implement database read replicas
- Add load balancing
### Long-Term Strategy
5. **Performance Monitoring**
- Set up continuous performance monitoring
- Implement automated performance regression testing
- Create performance budgets for new features
