Testing +- ✅ 401 Unauthorized +- ✅ 403 Forbidden +- ✅ 404 Not Found +- ✅ 400 Bad Request +- ✅ 201 Created (for resource creation) + +--- + +## Acceptance Criteria Compliance + +✅ **Add supertest-based tests for remittance** +- Create/submit ownership and status checks: 7 tests +- Covers unauthorized, forbidden, happy-path cases + +✅ **Add tests for score endpoints** +- Wallet-param-matches-JWT enforcement: 6 tests +- Score update with API key: 8 tests +- Credit band classification: 8 parameterized tests +- Covers unauthorized, forbidden, happy-path cases + +✅ **Add tests for admin dispute** +- Resolve/reject authorization paths: 12 tests +- Resolve confirm/reverse actions: 6 tests +- List and get disputes: 6 tests +- Covers unauthorized, forbidden, happy-path cases + +✅ **Cover at least unauthorized, forbidden, happy-path per controller** +- Remittance: 20 tests ✓ +- Score: 30+ tests ✓ +- Admin Dispute: 28 tests ✓ +- Notification: 28+ tests ✓ +- Auth: 28+ tests ✓ + +--- + +## Files

--testNamePattern="scoreController" --maxWorkers=1 +npm test -- --testNamePattern="adminDisputeController" --maxWorkers=1 +npm test -- --testNamePattern="notificationController" --maxWorkers=1 +npm test -- --testNamePattern="authController" --maxWorkers=1 + +# Run all tests +npm test +``` + +--- + +## Implementation Notes + +1. **Mocking**: All external services (database, cache, Soroban, notifications) are properly mocked to isolate controller logic +2. **Auth Simulation**: Real JWT tokens are generated using the production authService for authentic testing +3. **Ownership Verification**: Controllers correctly enforce wallet ownership and role-based access +4. **Status Transitions**: Tests verify proper state changes (pending → processing → completed/failed) +5. **Error Handling**: All error paths are tested with appropriate HTTP status codes +6. **Validation**: Input validation for all required fields is tested + +--- + +## Notes for Code Review + +- All tests follow the pattern established in loanEndpoints.test.ts +- Tests are isolated with beforeEach/afterAll cleanup +- Mock functions are reset between tests to prevent cross-test contamination +- Environment variables (JWT_SECRET, ADMIN_WALLETS, INTERNAL_API_KEY) are properly set and cleaned up +- Bearer token format follows RFC 6750 standard +- API key format follows x-api-key header
