Properties serve as the bridge between human-readable specifications and machine-verifiable correctness guarantees._ + +### Property 1: Schedule Validation + +_For any_ schedule configuration submitted to the API, the validation logic should correctly accept valid configurations and reject invalid configurations with a 400 status and descriptive error messages. + +**Validates: Requirements 1.2, 1.5** + +### Property 2: Schedule Persistence Round Trip + +_For any_ valid schedule configuration, after successful creation via POST /api/schedules, the returned schedule object should contain a unique identifier, a calculated next_run_timestamp, and all the submitted configuration data. + +**Validates: Requirements 1.3, 1.4** + +### Property 3: Active Schedule Retrieval Completeness + +_For any_ set of schedules in the database with mixed statuses, a GET request to /api/schedules should return only schedules with status 'active', and each returned schedule should include its identifier, configuration, and a calculated next_run_timestamp. + +**Validates: Requirements 2.2, 2.3, 2.4** + +### Property 4: Next Run Timestamp Calculation + +_For any_ schedule with a given frequency (once, weekly, biweekly, monthly), time of day, and start date, the calculated next_run_timestamp should correctly represent the next occurrence according to the frequency rules and should always be in the future relative to the current time (for new schedules) or relative to the last run time (for recurring schedules). + +**Validates: Requirements 2.3** + +### Property 5: Schedule Deletion Success + +_For any_ existing active schedule, a DELETE request to /api/schedules/:id with the correct schedule ID should return a 204 status, and subsequent queries should not return that schedule in the active schedules list. + +**Validates: Requirements 3.2, 3.3** + +### Property 6: Schedule Deletion Not Found + +_For any_ non-existent schedule ID, a DELETE request to /api/schedules/:id should return a 404 error. + +**Validates: Requirements 3.4** + +### Property 7: Due Schedule Identification + +_For any_ set of schedules with various next_run_timestamps, the cron job's query logic should retrieve exactly those schedules where next_run_timestamp <= current_time AND status = 'active', excluding all others. + +**Validates: Requirements 5.2** + +### Property 8: Payment Invocation Parameters + +_For any_ due schedule, when the cron job executes the payment, the parameters passed to the StellarService should exactly match the payment_config stored in the schedule (recipients, amounts, asset codes, memo). + +**Validates: Requirements 5.3** + +### Property 9: Successful Execution Recording + +_For any_ schedule execution that succeeds (payment transaction confirmed on blockchain), the execution_history table should contain a record with status 'success', the transaction hash, and the schedule's last_run_timestamp should be updated to the execution time. + +**Validates: Requirements 5.4** + +### Property 10: Failed Execution Recording + +_For any_ schedule execution that fails (payment transaction rejected or error occurs), the execution_history table should contain a record with status 'failed', an error message, and the schedule status should be marked as 'failed' to prevent retry loops. + +**Validates: Requirements 5.5** + +### Property 11: One-Time Schedule Completion + +_For any_ schedule with frequency 'once', after successful execution, the schedule status should be updated to 'completed' and it should not appear in subsequent queries for due schedules. + +**Validates: Requirements 5.6** + +### Property 12: Recurring Schedule Next Run Update + +_For any_ schedule with frequency 'weekly', 'biweekly', or 'monthly', after successful execution, the next_run_timestamp should be recalculated to the next occurrence based on the frequency, and the schedule status should remain 'active'. + +**Validates: Requirements 5.7** + +### Property 13: Malformed Request Handling + +_For any_ request with malformed JSON or missing required fields, the API should return a 400 error with a descriptive message indicating what is wrong with the request. + +**Validates: Requirements 6.2** + +### Property 14: Authorization Enforcement + +_For any_ schedule, when a user attempts to access or modify a schedule that belongs to a different organization, the API should return a 403 error regardless of whether the schedule exists. + +**Validates: Requirements 6.4** + +## Error Handling + +### API Error Handling Strategy + +The API implements comprehensive error handling at multiple layers: + +**Validation Layer:** + +- Request body validation using Joi or Zod schemas +- Type checking for all required fields +- Business rule validation (e.g., start_date not in past, valid frequency values) +- Returns 400 with structured error messages listing all validation failures + +**Authentication/Authorization Layer:** + +- JWT token validation via existing auth middleware +- Organization context extraction from authenticated user +- Schedule ownership verification before any read/update/delete operation +- Returns 401 for missing/invalid auth, 403 for insufficient permissions + +**Database Layer:** + +- Connection pool error handling with retry logic +- Transaction rollback on any failure during multi-step operations +- Deadlock detection and retry for concurrent schedule modifications +- Returns 503 for database unavailability, 500 for unexpected database errors + +**Blockchain Layer:** + +- Stellar transaction simulation before submission (using existing pattern) +- Network timeout handling with configurable retry attempts +- Transaction result parsing to distinguish between different failure types +- Errors logged to execution_history with full details for debugging + +### Cron Job Error Handling + +**Isolation:** Each schedule execution runs in isolation - failure of one schedule doesn't affect others + +**Retry Strategy:** + +- Failed schedules are marked with status 'failed' and not retried automatically +- Manual intervention required to investigate and reschedule +- Prevents infinite retry loops that could drain funds or spam the network + +**Logging:** + +- All execution attempts logged to execution_history table +- Error details include full stack trace and Stellar transaction result XDR +- Separate application logs for cron job health monitoring + +**Monitoring:** + +- Cron job heartbeat logged every execution cycle +- Metrics tracked: schedules processed, successes, failures, execution time +- Alerts configured for: consecutive failures, execution time exceeding threshold, no schedules processed for extended period + +### Frontend Error Handling + +The API provides structured error responses to enable meaningful user feedback: + +```typescript +interface ErrorResponse { + error: { + code: string; // Machine-readable error code + message: string; // Human-readable message + details?: object; // Additional context (e.g., validation errors) + }; +} +``` + +**Error Codes:** + +- `VALIDATION_ERROR`: Request validation failed +- `SCHEDULE_NOT_FOUND`: Schedule ID doesn't exist +- `UNAUTHORIZED`: Authentication required +- `FORBIDDEN`: Insufficient permissions +- `DATABASE_ERROR`: Database operation failed +- `BLOCKCHAIN_ERROR`: Stellar transaction failed +- `INTERNAL_ERROR`: Unexpected server error + +## Testing Strategy + +### Dual Testing Approach + +This feature requires both unit tests and property-based tests to ensure comprehensive coverage: + +**Unit Tests** focus on: + +- Specific examples of schedule creation with known inputs/outputs +- Edge cases like empty schedule lists, schedules at boundary times +- Error conditions like database connection failures, invalid auth tokens +- Integration points between controller, service, and database layers + +**Property-Based Tests** focus on: + +- Universal properties that hold across all valid schedule configurations +- Validation logic correctness across the input space +- Next run timestamp calculation accuracy for all frequency types +- Schedule lifecycle state transitions (active → completed/failed) + +### Property-Based Testing Configuration + +**Library:** `fast-check` for TypeScript/Node.js + +**Test Configuration:** + +- Minimum 100 iterations per property test +- Custom generators for schedule configurations, timestamps, payment configs +- Shrinking enabled to find minimal failing examples + +**Property Test Tags:** +Each property test must reference its design document property using this format: + +```typescript +// Feature: payroll-scheduler-backend-wiring, Property 1: Schedule Validation +test("validates schedule configurations correctly", async () => { + await fc.assert( + fc.asyncProperty(scheduleConfigArbitrary, async (config) => { + // Test implementation + }), + { numRuns: 100 }, + ); +}); +``` + +### Unit Testing Strategy + +**Controller Tests:** + +- Mock service layer to test request/response handling +- Verify correct status codes for success and error cases +- Test authentication/authorization middleware integration +- Validate request body parsing and error formatting + +**Service Tests:** + +- Mock database layer to test business logic +- Test next run timestamp calculation with known dates +- Verify schedule state transitions +- Test transaction handling (rollback on errors) + +**Cron Job Tests:** + +- Mock database and StellarService +- Test due schedule identification logic +- Verify payment parameter extraction +- Test execution history recording +- Verify state updates for one-time vs recurring schedules + +**Integration Tests:** + +- Test full API flow with real database (test database) +- Verify database schema and constraints +- Test concurrent schedule operations +- Verify transaction isolation + +### Test Data Generators + +For property-based tests, we need generators for: + +**Schedule Configurations:** + +```typescript +const scheduleConfigArbitrary = fc.record({ + frequency: fc.constantFrom("once", "weekly", "biweekly", "monthly"), + timeOfDay: fc + .tuple(fc.integer(0, 23), fc.integer(0, 59)) + .map( + ([h, m]) => + `${h.toString().padStart(2, "0")}:${m.toString().padStart(2, "0")}`, + ), + startDate: fc

Configurations:** + +```typescript +const invalidScheduleConfigArbitrary = fc.oneof( + fc.record({ frequency: fc.string() }), // Missing other fields + fc.record({ + ...validFields, + frequency: fc +

fc.date({ max: new Date(Date.now() - 86400000) }), + }), + fc.record({ ...validFields, paymentConfig: { recipients: [] } }), +); +``` + +### Coverage Goals + +- **Line Coverage:** Minimum 80% for all service and controller code +- **Branch Coverage:** Minimum 75% for error handling paths +- **Property Coverage:** All testable acceptance criteria covered by at least one property test +- **Integration Coverage:** All API endpoints tested with real database + +### Test Execution + +**Development:** + +```bash +npm test -- --watch +``` + +**CI/CD:** + +```bash +npm test -- --coverage --ci +npm run test:integration +npm run test:properties -- --numRuns=1000 +``` + +**Pre-deployment:** + +- All unit tests must pass +- All property tests must pass with 1000 iterations +- Integration
