React js Test Cases

 Writing react tests has been complicated and challenging because of the generalised dogma of testing implementation details over workability and user interactions and interfaces. This library is all about testing your applications based on how the user interacts with them, not only on how the functionality was implemented.

There is couple of test cases for react js

• https://testing-library.com/
• https://jestjs.io/docs/tutorial-react
• https://enzymejs.github.io/enzyme/

Testing library , test cases ::

import { render, screen } from '@testing-library/react';

import App from './App';

test('renders learn react link', () => {

  render(<App />);

  const linkElement = screen.getByText(/learn react/i);

  expect(linkElement).toBeInTheDocument();

});
