# CSCC01 Assignment 2 - CI/CD Submission (Team: Microsofties)

## What This Project Does
8+
9+
This project automates the CI/CD pipeline for a full-stack web application using:
10+
11+
- **GitHub Actions** for continuous integration and deployment
12+
- **Docker & Docker Hub** for containerization and versioning
13+
- **Render** for live deployment of frontend and backend containers
14+

## CI/CD Workflow
44+
45+
On every push to `main`, GitHub Actions will:
46+
47+
1. Run **unit tests** for both frontend and backend using Jest
48+
2. Build and tag Docker images (`latest` and versioned)
49+
3. Push images to Docker Hub
50+
4. Trigger **Render deploy hooks** for both frontend and backend
51+
5. Wait for services to go live
52+
6. Run **integration tests** by hitting live endpoints via `curl`
53+
54+
---
55+
56+
## Integration Tests
57+
58+
The integration tests (`scripts/integration-test.sh`) validate the deployed containers by:
59+
60+
- Hitting the backend health check at `/api/health`
61+
- Hitting a key backend API route `/api/water-data`
62+
- Checking that the frontend root (`/`) returns a response
63+
64+
---
65+
66+
## Environment Variables (Set in Render)
67+
68+
**Backend:**
69+
70+
- `MONGODB_URI` → MongoDB Atlas connection string
71+
- `JWT_SECRET` → Secret key for token generation
72+
73+
**Frontend:**
74+
75+
- `REACT_APP_API_URL` → URL of deployed backend (e.g., `https://glow-backend-v4-0-0.onrender.com`)
76+
77+
---
78+
79+
## Manual Test Commands (Optional)
80+
81+
From project root:
82+
83+
```bash
84+
# Run backend locally
85+
cd backend
86+
npm install
87+
npm test
88+
89+
# Run frontend locally
90+
cd frontend
91+
npm install
92+
npm test
93+
94+
# Run integration test against deployed services
95+
bash CICD/scripts/integration-test.sh
