React.js library is all about splitting the app into several components. Each Component has its own lifecycle. React provides us some in-built methods that we can override at particular stages in the life-cycle of the component.

In this article, we will know how to use testInstance.props property. The testInstance.props property is used to get a prop which is corresponding to the test instance.

Creating React Application And Installing Module:

  • Step 1: Create a React application using the following command

    npx create-react-app foldername
  •  
  • Step 2: After creating your project folder i.e. foldername, move to it using the following command.

    cd foldername
  • Step 3: After creating the ReactJS application, Install the required module using the following command:

    npm install react-test-renderer

Project Structure: It will look like the following.

Example 1:

Javascript

import React from 'react';
import TestRenderer from 'react-test-renderer';
  
// Defining our App Component
const App = () => {
  
// Function to demonstrate TestRenderer.props property
function func(){
    const renderer = TestRenderer.create(
        <div>
            GeeksforGeeks
            <div>
                TestRenderer.props property
            </div>
        </div>
      );
    const myprops = renderer.root;
    console.log(myprops.props);
  
}
func();
  
// Returning our JSX code
return <>
      
</>;
}
  
// Exporting your Default App Component
export default App
