Job 1: Test

This job ensures the backend code is functional and passes all tests before deployment.

Working Directory: ./backend

Steps:

1. Checkout Code:

   • The repository code is checked out.

2. Setup Node.js:

   • Dependencies are cached using package-lock.json.

3. Install Dependencies:

   • Dependencies are installed using npm.

4. Run Tests:

   • Automated tests are executed using npm test.

---

Job 2: Deploy

If the tests pass successfully, the deployment job starts.

Working Directory: ./backend
Dependency: Relies on the test job completing successfully.

Steps:

1. Checkout Code:

   • The repository code is checked out.

2. Setup Node.js:

   • Node.js installed.
   • Dependencies are cached.

3. Install Dependencies:

   • Production dependencies are installed.

4. Prepare Deployment Package:
