🛠️ 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
