What is TestRenderer package in React?

This package provides a renderer that can be used to render components to pure JavaScript objects, without depending on the DOM or a native mobile environment. This package makes it easy to grab a snapshot of the platform view hierarchy (similar to a DOM tree) rendered by a ReactDOM or React Native without using a browser or jsdom.

import TestRenderer from 'react-test-renderer';
const Link = ({ page, children }) => <a href={page}>{children}</a>;
const testRenderer = TestRenderer.create(
<Link page={'https://www.facebook.com/'}>{'Facebook'}</Link>,
);
console.log(testRenderer.toJSON());
// {
// type: 'a',
// props: { href: 'https://www.facebook.com/' },
// children: [ 'Facebook' ]
// }
