## Test Coverage Enhancement

### **Before Migration**
- Basic sanitization tests
- Simple compression tests
- Basic rate limiting tests
- Limited integration scenarios

### **After Migration** 
- ✅ **Comprehensive sanitization**: XSS, SQL injection, schema validation, performance
- ✅ **Advanced compression**: Multiple algorithms, performance benchmarks, error handling
- ✅ **Full rate limiting**: Whitelist/blacklist, burst handling, multi-client scenarios
- ✅ **Complete integration**: End-to-end workflows, error propagation, performance measurement
- ✅ **Edge case coverage**: Configuration validation, error handling, performance limits

## Key Improvements

### **1. Test Consistency**
- Converted Jest syntax to Node.js assert for consistency
- Standardized test structure across all files
- Unified mock implementations

### **2. Enhanced Coverage**
- Added performance tests for large datasets
- Included error handling scenarios
- Added configuration validation tests
- Enhanced security testing

### **3. Better Organization**
- Logical separation of concerns
- Clear test categories and grouping
- Improved test discovery and maintenance

### **4. Realistic Scenarios**
- Integration tests with multiple middleware components
- Performance testing with realistic data sizes
- Error propagation testing
- Configuration edge cases

## Running Enhanced Tests

### **Individual Components**
```bash
# Run specific enhanced middleware tests
npm run test:enterprise:sanitization    # 10+ test cases
npm run test:enterprise:compression     # 15+ test cases  
npm run test:enterprise:rate-limiting   # 12+ test cases

# Run integration tests
npm run test:enterprise:integration     # 20+ test cases
```

### **Full Test Suite**
```bash
# Run all enhanced tests with comprehensive reporting
npm run test:enterprise:full

# Run all tests including enhancements
npm run test:all
```

## Validation Results
