Setting Up Jest: Your Node.js Backend Testing Toolkit

Welcome back to our unit testing journey! In this section, we'll guide you through the seamless process of integrating Jest into your Node.js backend project. Don't worry, it's simpler than you might think!

Prerequisites :

• Assuming you have installed the latest version of node js in your system. If not click on me

• Your preferred IDE is installed on your system.I prefer VS code.

Installation Made Easy

1. Fire Up Your Terminal: Open your terminal and navigate to the root directory of your Node.js project.

2. Run the below command to initialize the empty node project.

    npm init -y
   

3. Install with npm: If you're using npm, execute the following command:

    npm install --save-dev jest
   

4. Note: If your project uses modern JavaScript features (e.g.,import/export), consider adding "type": "module" to your package.json file:

5. Add the test Script in the package.json file

      "scripts": {
        "test": "jest"
      },
   

What's Next?

In the next section, we'll get our hands dirty by writing our first Jest tests. Get ready to unleash the power of unit testing and create a rock-solid foundation for your Node.js backend applications!

Stay tuned for more interactive learning and remember: a well-tested backend is a happy backend.
