# Infrastructure Testing TODOs

## Overview
Critical infrastructure testing gaps that form the foundation for all other testing efforts.

---

## 🔴 High Priority Items

### infra-001: Create comprehensive test database setup and seeding utilities
**File Location**: `tests/setup/database.ts` (new)
**Description**: Current tests rely on mocks and lack real database integration
**Impact**: High - Without real DB testing, data integrity issues go undetected
**Estimated Effort**: 16 hours

**Specific Tasks**:
- [ ] Create test database configuration separate from production
- [ ] Implement database migration scripts for test environment
- [ ] Create test data seeding utilities
- [ ] Add database cleanup/rollback mechanisms
- [ ] Set up transaction-based test isolation

**Implementation Notes**:
```typescript
// Example structure needed
export class TestDatabaseManager {
  static async setupTestDb(): Promise<void>
  static async seedTestData(): Promise<void>
  static async cleanupTestDb(): Promise<void>
  static async withTransaction<T>(fn: () => Promise<T>): Promise<T>
}
```

### infra-002: Implement coverage thresholds and enhanced reporting configuration
**File Location**: `vitest.config.ts`
**Description**: No coverage thresholds or proper reporting setup
**Impact**: High - No quality gates to prevent coverage regression
**Estimated Effort**: 8 hours

**Specific Tasks**:
- [ ] Set coverage thresholds (80% global minimum)
- [ ] Configure HTML and JSON coverage reports
- [ ] Add coverage reporting to CI/CD pipeline
- [ ] Implement per-module coverage tracking
- [ ] Add uncovered line highlighting in reports

**Implementation Notes**:
```typescript
// Add to vitest.config.ts
coverage: {
  thresholds: {
    global: { branches: 80, functions: 80, lines: 80, statements: 80 },
    // Critical modules higher thresholds
    './lib/': { branches: 90, functions: 90 },
    './actions/': { branches: 85, functions: 85 }
  },
  reporter: ['text', 'html', 'json', 'lcov']
}
```

### infra-003: Create standardized test factories and fixtures for consistent test data
**File Location**: `tests/factories/` (new directory)
**Description**: Manual test data creation leads to inconsistent tests
**Impact**: High - Test reliability and maintainability issues
**Estimated Effort**: 12 hours

**Specific Tasks**:
- [ ] Create user factory with different roles
- [ ] Create product factory with variants
- [ ] Create order factory with different states
- [ ] Create cart factory with various scenarios
- [ ] Implement faker.js integration for realistic data

**Implementation Notes**:
```typescript
// Example factory structure
export const createUser = (overrides = {}) => ({
  id: faker.uuid(),
  email: faker.internet.email(),
  name: faker.person.fullName(),
  role: 'user',
  ...overrides
});
```

## 🟢 Medium Priority Items

### infra-004: Establish centralized mock strategy with service-level isolation
**File Location**: `tests/mocks/` (new directory)
**Description**: Inconsistent mocking patterns across test files
**Impact**: Medium - Test maintenance and reliability issues
**Estimated Effort**: 16 hours

**Specific Tasks**:
- [ ] Create centralized mock registry
- [ ] Implement service-level mock isolation
- [ ] Standardize mock data versioning
- [ ] Add mock validation against real API contracts
- [ ] Create mock data reset utilities

---

### infra-005: Add performance testing framework with benchmarks and monitoring
**File Location**: `tests/performance/` (new directory)
**Description**: No performance monitoring or benchmarking capability
**Impact**: Medium - Performance regressions go undetected
**Estimated Effort**: 20 hours

**Specific Tasks**:
- [ ] Create performance testing utilities
- [ ] Implement response time measurements
- [ ] Add memory usage monitoring
- [ ] Create baseline performance benchmarks
- [ ] Set up performance regression detection

---

### infra-006: Implement CI/CD integration with test database provisioning
**File Location**: `.github/workflows/` (modify existing)
**Description**: CI lacks proper test environment setup
**Impact**: Medium - CI tests may not reflect real scenarios
**Estimated Effort**: 12 hours

**Specific Tasks**:
- [ ] Add test database setup to CI pipeline
- [ ] Implement Redis instance for testing
- [ ] Add Stripe test configuration
- [ ] Set up test environment variables
- [ ] Configure test result aggregation

---

## Dependencies and Order

**Phase 1** (Week 1):
1. infra-001 (Test database setup) - Foundation for all other testing
2. infra-003 (Test factories) - Needed for consistent test data

**Phase 2** (Week 2):
3. infra-002 (Coverage configuration) - Quality gates
4. infra-006 (CI/CD integration) - Automation

**Phase 3** (Future):
5. infra-004 (Mock strategy) - Long-term maintainability
6. infra-005 (Performance framework) - Performance monitoring

---

## Success Metrics

- Database setup time: <30 seconds
- Test data generation: <5 seconds per test suite
- Coverage report generation: <10 seconds
- CI test execution: <10 minutes total
- Mock strategy consistency: 100% new tests follow pattern

---

## Notes for Implementation

1. **Database Strategy**: Consider using Docker containers for isolated test databases
2. **Factory Pattern**: Use Factory Boy or similar pattern inspiration
3. **Performance Tools**: Investigate Lighthouse CI, Artillery for load testing
4. **Mock Strategy**: Follow MSW (Mock Service Worker) patterns for API mocking
5. **CI Optimization**: Use test parallelization and caching for faster CI runs
