GoodGo Platform AI - Test Coverage Audit Report

Date: April 10, 2026 Repository: /Users/velikho/Desktop/WORKING/goodgo-platform-ai/apps/api/src/modules/

---

EXECUTIVE SUMMARY

This audit analyzes test coverage across three critical modules in the GoodGo Platform AI backend:

Module	Source Files	Test Files	Coverage
Listings	42	13	31%
Auth	56	21	38%
Search	22	10	45%
TOTAL	120	44	37%

Key Finding: While test files exist for major handlers and domain entities, many critical infrastructure services, value objects, repositories, and presentation layer components lack test coverage.

   • infrastructure/services/prisma-duplicate-detector.spec.ts
   • infrastructure/services/prisma-price-validator.spec.ts
   • domain/services/moderation.service.spec.ts

Short Term (Week 2-3)

3. Infrastructure Repository Tests:

   • All Prisma repository implementations
   • Search repository implementations

4. Integration/Event Tests:

Conclusion

The GoodGo Platform AI monorepo has a 37% test coverage across the three critical modules examined, with significant gaps in:

• Security-critical guards and strategies (AUTH)
• Infrastructure data access layers (all modules)
• Presentation layer controllers and DTOs (all modules)
• Domain event models (LISTINGS & AUTH)

The Search module shows the strongest test coverage at 45%, with most handlers and services tested. The Listings and Auth modules need immediate attention to the security and business logic components identified in Tier 1 recommendations.
