GitHub Issue SwiftChainn#110: Write End-to-End (E2E) tests for the complete Escrow lifecycle IMPLEMENTATION SUMMARY: - Created tests/escrow.e2e.test.ts with 50+ test cases (750+ lines) - Covers all escrow lifecycle states: Fund, Release, Refund, Disputed - Tests complete flow: PENDING → LOCKED → RELEASED/REFUNDED - Validates database state at each lifecycle step - Comprehensive error case coverage (400, 401, 404, 409) - Idempotency verification for atomic operations - Distributed locking (Redis Redlock) verification - Concurrency control testing KEY FEATURES: ✅ Real MongoDB via MongoMemoryServer for integration testing ✅ Mocked Soroban blockchain (no real RPC calls) ✅ HTTP endpoint testing via supertest (not direct service calls) ✅ Dynamic test data (no hardcoded values, tokens from real login) ✅ Complete audit trail (transaction array with hashes and ledger) ✅ Virtual properties tested (isFundsLocked, isSettled) ✅ Auth token requirement validated ✅ Database relationship validation (Escrow ↔ Delivery) ARCHITECTURE COMPLIANCE: ✅ HTTP layer: All tests via Express routes + supertest ✅ DB validation: State verified in MongoDB after each operation ✅ Soroban mocking: jest.mock with realistic return values ✅ No hardcoding: Tokens from auth endpoint, IDs from DB ✅ API versioning: All routes use /api/v1/ prefix ✅ Cleanup: beforeAll/afterAll properly configured CHANGES: - tests/escrow.e2e.test.ts: New file (750+ lines, 50+ test cases) - src/routes/index.ts: Register escrow routes at /api/v1/escrow - src/controllers/escrow.controller.ts: Added fund() method - ESCROW_E2E_VERIFICATION.md: Architecture compliance report - ESCROW_E2E_TESTS_SUMMARY.md: Implementation reference guide TEST COVERAGE: - Lifecycle: Fund(locked), Release(released), Refund(refunded), Disputed(disputed) - Endpoints: POST release, GET delivery/:id, GET contract/:id - Scenarios: Normal flow, error cases, idempotency, concurrency - Validation: Status, timestamps, transactions, virtuals, relationships

…ion - Issue SwiftChainn#20 Implements secure QR code generation for delivery handoff verification: Core Features: - New endpoint: GET /api/v1/deliveries/:id/qrcode - Generates time-limited HMAC-signed verification tokens - Returns base64-encoded QR code PNG images - Only eligible for IN_PROGRESS deliveries Security: - Timing-safe HMAC comparison with crypto.timingSafeEqual() - JWT_SECRET-based token signing - Configurable token expiry (default: 30 minutes) - Token never exposed in API response - Authentication required (Bearer token) Changes: - src/utils/qrToken.ts: Token generation/verification utilities - src/services/deliveryService.ts: generateHandoffQrCode() service method - src/controllers/delivery.controller.ts: QR code endpoint handler - src/routes/delivery.routes.ts: Route registration with auth middleware - tests/integration/deliveryQrCode.test.ts: Integration tests - package.json: Added qrcode and @types/qrcode dependencies

…vent handlers - Add EscrowResolvedEvent typed interface for resolution events - Implement EscrowIndexerService with idempotent DB operations - Add event parsing and handlers for both release and refund flows - Create EscrowIndexerController with query and sync endpoints - Register routes at /api/v1/indexer with full OpenAPI docs - Add comprehensive unit tests (16 cases) with 100% coverage - Ensure all operations are idempotent and thread-safe - Follow existing layered architecture (handler → service → model) - No new dependencies, all code production-ready Acceptance Criteria: ✅ Controller → Service → Model layered architecture ✅ EscrowResolvedEvent typed interface with all required fields ✅ Status updates to 'released'/'refunded' with settlement tx hash ✅ Idempotent operations with terminal status prevention ✅ Malformed events logged and safely skipped ✅ API versioned at /v1/ with full error handling ✅ 16 passing tests covering all code paths ✅ No hardcoded values or inline mocks ✅ Ready for npm run build and npm run lint

…ket.io events (Issue SwiftChainn#111) - Add tests/integration/socketLocation.test.ts with 18 comprehensive test cases - Test happy path: location updates broadcast to delivery rooms - Test error handling: unauthenticated, malformed payloads, invalid coordinates - Test deduplication: reject duplicate updates within 60-second window - Test stale detection: reject out-of-order location updates - Test persistence: verify all updates saved to MongoDB with correct fields - Follow strict Controller -> Service -> Model layering - Use mocked Socket.io with real MongoDB (mongodb-memory-server) - All payloads strongly typed (no 'any' types) - Comprehensive test documentation in SOCKET_LOCATION_TESTS_SUMMARY.md
