+### 8. Test Execution Guide (Session 2)
+
+#### File Created
+- `TEST_EXECUTION_GUIDE.md` - Comprehensive testing strategy (400+ lines)
+
+**Guide Contents**:
+1. **Test Infrastructure Status**:
+   - ✅ Unit Tests: 92/92 passing (EXECUTED)
+   - ⏳ Load Tests: Scripts ready (K6 CLI installation required)
+   - ⏳ E2E Tests: Scripts ready (requires frontend + backend running)
+   - ⏳ API Tests: Collection ready (requires backend running)
+
+2. **Prerequisites & Installation**:
+   - K6 CLI installation instructions (macOS, Windows, Linux)
+   - Playwright setup (v1.56.0 already installed)
+   - Newman/Postman CLI (available via npx)
+   - Database seeding requirements
+
+3. **Test Execution Instructions**:
+   - Unit tests: `npm test` (apps/backend)
+   - Load tests: `k6 run load-tests/rate-search.test.js`
+   - E2E tests: `npx playwright test` (apps/frontend/e2e)
+   - API tests: `npx newman run postman/collection.json`
+
+4. **Performance Thresholds**:
+   - Request duration (p95): < 2000ms
+   - Failed requests: < 1%
+   - Load profile: 0 → 20 → 50 → 100 users (7 min ramp)
+
+5. **Test Scenarios**:
+   - **E2E**: Login → Rate Search → Booking Creation → Dashboard Verification
+   - **Load**: 5 major trade lanes (Rotterdam↔Shanghai, LA→Singapore, etc.)
+   - **API**: Auth, rates, bookings, organizations, users, GDPR
+
+6. **Troubleshooting**:
+   - Connection refused errors
+   - Rate limit configuration for tests
+   - Playwright timeout adjustments
+   - JWT token expiration handling
+   - CORS configuration
+
+7. **CI/CD Integration**:
+   - GitHub Actions example workflow
+   - Docker services (PostgreSQL, Redis)
+   - Automated test pipeline
