# ⚙️ CI/CD Pipeline with GitHub Actions & API Testing
A mini-project demonstrating **CI/CD pipeline implementation using GitHub Actions** and **automated API route testing** with **Jest** and **Supertest** for a Node.js Express application.
---
## 📌 What is CI/CD?
**CI/CD** stands for:
- **Continuous Integration (CI)** – Automatically test and build your app whenever you push code to the repository.
- **Continuous Deployment (CD)** – Automatically deploy the app when the tests pass, ensuring your latest code is always live.
These pipelines:
- Detect code changes (`git push`)
- Run test suites
- Deploy only on success
- Eliminate manual errors & reduce dev-ops overhead
---
## ⚙️ What are GitHub Actions?
**GitHub Actions** is an automation tool provided by GitHub. You can define custom workflows in `.yml` files to:
- Run tests
- Build and deploy code
- Trigger jobs based on events like commits or pull requests
This project uses a GitHub Action to:
1. Install dependencies
2. Run tests
3. Deploy via a Render deploy hook (only if all tests pass ✅)
---
## 🧪 What is Unit Testing using Jest & Supertest?
### **Jest**:
A JavaScript testing framework by Facebook for writing unit tests. It supports:
- Assertions (`expect(...)`)
- Mocks and spies
- Test runners
### **Supertest**:
A high-level abstraction to test HTTP endpoints. It simulates requests and checks responses without needing to deploy the server externally.
### 🔍 Example:
```js
it("GET / returns Hello World", async () => {
const res = await request(app).get("/");
expect(res.statusCode).toBe(200);
expect(res.text).toBe("Hello World");
});
```

## 🚀 Project Overview
This mini-project includes:
- A simple Express server with two routes:
- `/` → Returns `Hello World`
- `/:id` → Returns `Hello World `
- Test cases for both routes using **Jest** and **Supertest**
- A GitHub Actions workflow to automatically:
- Install dependencies
- Run tests
- Deploy to Render (if tests pass)
---
## ✅ Correct Test Results
When the routes are implemented correctly, **all test cases pass** successfully:
---
## ❌ Failed Test Results
If any route is broken or missing, **relevant test cases fail**, ensuring reliability:
## 
---
## ✅ Automated Testing via GitHub Actions
Every code push triggers **automated testing on GitHub Actions**.
If any route fails, the pipeline halts — ensuring only **fully tested, reliable code** gets deployed.
---
## 📁 Tech Stack
- **Node.js / Express**
- **Jest** for testing logic
- **Supertest** for endpoint testing
- **GitHub Actions** for CI/CD automation
- **Render** for deployment (via deploy hook)
---
## 🧠 Learning Outcomes
✅ Understand CI/CD and GitHub Actions
✅ Build & test Express routes
✅ Automate testing and deployment pipeline
✅ Visualize real test outcomes (pass vs fail)
