## 🧪 TESTING PROTOCOLS

### Testing Pyramid
```
    E2E Tests (Few)
   ┌─────────────┐
   │  UI Tests   │
   └─────────────┘
  ┌───────────────┐
  │ Integration   │
  │    Tests      │
  └───────────────┘
 ┌─────────────────┐
 │   Unit Tests    │
 │     (Many)      │
 └─────────────────┘
```

### Test Categories
**Unit Tests (70%):**
- Individual function/method testing
- Fast execution (< 1ms per test)
- No external dependencies
- High coverage of business logic

**Integration Tests (20%):**
- Component interaction testing
- Database/API integration
- Service-to-service communication
- Moderate execution time

**End-to-End Tests (10%):**
- Full user workflow testing
- Browser automation
- Critical path validation
- Slower execution time

### Testing Commands
{TESTING_COMMANDS_SPECIFIC}

### Test Data Management
**Test Database:**
```bash
# Setup test database
npm run test:db:setup

# Seed test data
npm run test:db:seed

# Reset between tests
npm run test:db:reset
```

**Mock Data Strategy:**
- Use factories for consistent test data
- Mock external APIs in unit tests
- Use real data in integration tests
- Sanitize production data for testing

## 🚀 DEPLOYMENT PIPELINE

### Environment Strategy
**Environment Progression:**
```
Development → Staging → Production
     ↓            ↓         ↓
   Feature     Integration  Live
   Testing      Testing    System
```

### Deployment Process
**Automated Deployment (CI/CD):**
1. **Trigger**: Push to main branch
2. **Build**: Compile and bundle code
3. **Test**: Run full test suite
4. **Security**: Vulnerability scanning
5. **Deploy**: Deploy to target environment
6. **Verify**: Health checks and smoke tests

**Manual Deployment Steps:**
```bash
# 1. Prepare deployment
npm run build
npm run test:full
npm run lint:check

# 2. Database migrations (if needed)
npm run db:migrate

# 3. Deploy application
npm run deploy:staging  # or deploy:production

# 4. Verify deployment
npm run health:check
npm run smoke:test
```

### Rollback Procedures
**Automated Rollback Triggers:**
- Health check failures
- Error rate above threshold
- Performance degradation
- User-reported critical issues

**Manual Rollback Process:**
```bash
# 1. Identify last known good version
git log --oneline -10

# 2. Create rollback branch
git checkout -b rollback/to-version-X.Y.Z

# 3. Deploy previous version
npm run deploy:rollback --version=X.Y.Z

# 4. Verify rollback success
npm run health:check
```
