# Test Strategy for {module_name}

## Module Assessment
- **Module**: {module_name}
- **Complexity**: {complexity}
- **Business Impact**: {business_impact}

## Testing Approach

### 1. Test Categories
Based on the module's complexity and business impact:

#### Unit Tests (Priority: High)
- Test individual functions and methods
- Focus on business logic validation
- Include edge cases and error conditions
- Target: 95% line coverage

#### Integration Tests (Priority: Medium)
- Test component interactions
- Validate business process flows
- Include external dependency mocking
- Target: 85% integration coverage

#### Performance Tests (Priority: {'High' if business_impact == 'critical' else 'Medium'})
- Benchmark critical operations
- Validate 6M logs/sec capability
- Memory usage and leak detection
- Concurrent operation testing

#### Compliance Tests (Priority: {'High' if business_impact in ['high', 'critical'] else 'Medium'})
- GDPR compliance validation
- HIPAA compliance testing
- SOC2 security requirements
- PCI-DSS data protection

### 2. Test Implementation Strategy

#### Phase 1: Core Functionality
1. Identify critical business functions
2. Create comprehensive unit tests
3. Implement business logic validation
4. Add performance benchmarks

#### Phase 2: Integration & Edge Cases
1. Test component interactions
2. Validate error handling
3. Test boundary conditions
4. Add concurrent operation tests

#### Phase 3: Compliance & Security
1. Implement compliance tests
2. Add security validation
3. Test data protection measures
4. Validate audit trail functionality

### 3. Success Metrics
- **Coverage Target**: 90%+ for critical modules
- **Performance Target**: Meet 6M logs/sec requirement
- **Compliance Target**: 100% compliance test pass rate
- **Business Value**: Reduce production risk by 50%

### 4. Implementation Guidelines
1. Use Storm Logger test fixtures for consistency
2. Follow business intelligence testing patterns
3. Include enterprise-grade assertions
4. Implement proper test isolation
5. Add comprehensive error testing

This strategy ensures that {module_name} meets Storm Logger's enterprise standards and business requirements.
