ReactJs — React Testing with Jest and React Testing Library

Testing ensures your components work correctly. Jest is a testing framework, and React Testing Library provides utilities to test React components effectively.

import { render, screen } from '@testing-library/react';
import '@testing-library/jest-dom';
import Button from './Button';

test('renders button with correct label', () => {
  render(<Button label="Click Me" onClick={() => {}} />);
  expect(screen.getByText('Click Me')).toBeInTheDocument();
});
