Test a MEAN Stack Todo Application with JEST

PROJECT


Test a MEAN Stack Todo Application with JEST

In this project, we’ll learn how to build a Todo application using MEAN stack and write test scripts to test both the frontend and backend of the application using Jest.

Test a MEAN Stack Todo Application with JEST

You will learn to:

Develop the application’s backend using Node.js and Express.js to handle server-side logic.

Utilize Jest for conducting unit tests within the Angular framework.

Leverage Jest for conducting tests in Node.js.

Utilize MongoDB as the database to efficiently store and manage data.

Project Description

In this project, we’ll use the MEAN stack to create a robust Todo application. We’ll use MongoDB for data storage, Express.js for back-end development, Angular for front-end development, and Node.js to execute server-side logic, delivering a seamless user experience. The focal point revolves around robust MEAN stack testing, particularly with Jest.

The backend will be tested using Jest to validate the functionality of API endpoints. This includes testing the creation, updating, and deletion of Todo items to ensure reliable server-side operations.

The frontend will provide an intuitive and responsive user interface for managing tasks. Users can create, edit, and mark items as completed. Extensive Jest tests will be implemented to assess the functionality of the frontend, covering areas such as item listing, adding, and deleting. This approach aims to guarantee the stability and correctness of the application throughout the development process.

The final layout of the application will look like this:
