## 🛠️ Implementation Roadmap

### Week 1: Critical Tests (11 files, ~22 hours)
Focus on security and business logic:
- JWT authentication guard
- Role-based authorization
- User data repository
- Duplicate detection service
- Price validation service
- Listing repository
- Moderation business logic
- Search integration

### Week 2-3: Infrastructure (9 files, ~15 hours)
Focus on data access and services:
- Remaining repositories
- Authentication strategies
- Event handlers

### Week 4: Presentation (6 files, ~12 hours)
Focus on controllers and decorators:
- Auth controllers
- Guards and decorators
- Listing controller

### Week 5+: Remaining (13 files, ~10 hours)
- DTO validation tests
- Module configuration
- E2E integration tests

## 🎓 Test Type Recommendations

Based on the audit, you'll need:

1. **Unit Tests** (50 min/file avg)
   - Services, domain entities, value objects
   - Total: ~20 files

2. **Integration Tests** (60 min/file avg)
   - Repositories, event handlers
   - Total: ~18 files

3. **Guard/Decorator Tests** (30 min/file avg)
   - Security & request handling
   - Total: ~8 files

4. **Controller Tests** (40 min/file avg)
   - Endpoint routing & responses
   - Total: ~5 files

5. **DTO Tests** (20 min/file avg)
   - Input validation
   - Total: ~12 files

Total estimated effort: **~60 hours** to reach 70%+ coverage
