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
Â
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>             neveropen             <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 |
