Project Overview "simpleloginjs" is a straightforward Node.js application designed to handle basic login functionality. It utilizes the Express.js framework for handling HTTP requests and Body-Parser for parsing incoming request bodies. The project also includes automated tests written with Mocha to ensure the correctness of the login logic.

Key Features Express.js: Provides a robust framework for building web applications and APIs. Body-Parser: Middleware to parse incoming request bodies in a middleware before your handlers. Mocha: A feature-rich JavaScript test framework running on Node.js, making asynchronous testing simple and fun. Project Structure app.js: The main application file that sets up the Express server and defines the login routes. login.test.js: Contains the Mocha test cases to validate the login functionality. package.json: Lists the project dependencies and scripts. CI/CD Pipeline The project leverages GitLab CI/CD to automate the build, test, and deployment processes. The CI/CD pipeline is designed to ensure code quality, reliability, and efficiency through the following stages:

Install:

Installs all project dependencies using npm install. Caches the node_modules directory to speed up subsequent pipeline runs. Build:

Installs dependencies for the main branch (optional setup for build processes). Ensures that the build process is reproducible and dependencies are correctly managed. Run:

Starts the application server using npm start. Waits for the server to initialize before proceeding to the test stage. Test:

Executes automated tests using Mocha to validate the login functionality. Ensures that the server is running and ready for testing, preventing connection errors and timeouts.
