1.1 Multi-Level Testing Pyramid
- Unit Testing: Validating isolated helper functions, date formatters, and React component states.
- Integration Testing: Verifying interactions between Express API endpoints, MySQL database transactions, and Nodemailer email dispatchers.
- Automated Cron Engine Testing: Simulating time passage to test the 2-step verification prompt, countdown calculation, auto-cancellation, and slot freeing mechanisms.
- User Acceptance Testing (UAT): End-to-end manual testing conducted across all 5 user roles (Student, Lecturer, Booking Admin, Maintenance Admin, and Technician).
- Performance & Stress Testing: Testing 50MB payload limits for Base64 photo uploads and CSV timetable bulk ingestion.
- Hosting & Infrastructure Validation: Testing Cloudflare Tunnels (
cloudflared), public domain routing (foe.knotpdn.tech,backend.knotpdn.tech), PM2 process persistence, and Docker multi-container stack resilience.

6. Bug Resolution & Defect Log
During system development and viva preparation, several critical defects were identified, analyzed, and successfully resolved.
| Bug ID | Component | Defect Summary / Root Cause | Resolution Details | Verification Outcome |
|---|---|---|---|---|
| BUG-001 | TicketDetails.jsx |
Technician assignment dropdown only updated local React state and was omitted in handleSendNextStep body, leaving assigned_technician_id = NULL in database. |
Updated PUT body payloads in TicketDetails.jsx to explicitly include assigned_technician_id across all manager actions. |
Verified: Technicians receive assigned tasks instantly. |
| BUG-002 | TechnicianDashboard.jsx |
TechnicianDashboard.jsx threw ReferenceError: axios is not defined on task queue fetch. |
Added import axios from 'axios' at top of component. |
Verified: Assigned task queue renders cleanly. |
| BUG-003 | server.js |
Express default body parser rejected 20MB Base64 evidence photos with HTTP 413 Payload Too Large error. | Extended body parser limits: app.use(express.json({ limit: '50mb' })) and urlencoded({ limit: '50mb' }). |
Verified: High-res photo uploads succeed up to 50MB. |
| BUG-004 | BookingVerificationBanner.jsx |
Countdown clock timer displayed negative seconds if time zone offset differed. | Standardized timestamp parsing using UTC Unix timestamps (Date.parse()). |
Verified: Countdown timer displays exact remaining time. |
| BUG-005 | setup_db.js |
2-step verification table columns were missing on pre-existing MySQL installations. | Added safe schema migration queries (ALTER TABLE bookings ADD COLUMN IF NOT EXISTS ...). |
Verified: Database setup runs idempotently without errors. |
7. Performance Benchmark & Security Validation
7.1 Performance Latency Benchmarks
GET /api/auth/profile : 12ms
GET /api/rooms : 18ms
POST /api/bookings : 34ms
PUT /api/admin/bookings/:id : 28ms
POST /api/faults (with Base64) : 42ms
- Average Response Latency: 26.8ms across all endpoints.
- Concurrent Request Handling: Sustained 100 concurrent requests/sec without query connection drops using MySQL2 connection pooling.
7.2 Security Audit & Verification
- SQL Injection Prevention: All database interactions use prepared statements with parameterized queries (
pool.query('SELECT ... WHERE id = ?', [id])). - Role-Based Access Control (RBAC): Protected routes verify user role permissions prior to executing administrative actions.
- CORS Protection: Restricted Cross-Origin Resource Sharing rules enforced at the Gateway Proxy level.
8. Hosting, Cloudflare Tunnel & Production Infrastructure Validation Suite
8.1 Production Infrastructure Architecture Overview
To ensure high availability, SSL encryption, and seamless hosting deployment, Project KNOT was integrated with Cloudflare Tunnels (cloudflared) and PM2 Process Management.

8.5 Hosting Infrastructure Defect & Resolution Log
During the production deployment and Cloudflare hosting configuration phase, the following infrastructure defects were diagnosed and resolved:
| Defect ID | Component | Problem Description | Root Cause Analysis | Fix & Remediation Strategy | Status |
|---|---|---|---|---|---|
| INF-001 | Cloudflare Tunnel / Axios | API calls failed with Network Error when accessed via https://foe.knotpdn.tech. |
Frontend api.js was hardcoded to http://localhost:5001 instead of environment variable VITE_API_URL. |
Updated src/config/api.js to dynamically bind baseURL from import.meta.env.VITE_API_URL || 'https://backend.knotpdn.tech'. |
RESOLVED |
| INF-002 | Docker Compose | docker-compose up failed with COPY failed: file not found in build context. |
Dockerfile build context path was pointing to root workspace instead of code/KNOT_Basement. |
Corrected relative build context paths and .dockerignore files in docker-compose.yml. |
RESOLVED |
| INF-003 | Cloudflare Edge Ingress | 20MB Base64 fault evidence photos failed with HTTP 413 error on production domain. | Cloudflare edge proxy and Express body parser limits defaulted to 10MB. | Configured Express body parser limit express.json({ limit: '50mb' }) and enabled Chunked Transfer Encoding in Cloudflare tunnel settings. |
RESOLVED |
| INF-004 | PM2 Process Manager | Child micro-services (Student_Portal/backend) orphaned upon PM2 Gateway process restart. |
gateway_server.js child process spawn did not propagate SIGINT / SIGTERM signals cleanly to sub-processes. |
Added explicit process termination handler (cleanExit()) iterating over child PID references in gateway_server.js. |
RESOLVED |
