How do I use React Testing Library for my React app?

To use React Testing Library, first install it with npm or yarn. Then, you can write tests using the render function to mount your components.

Can you show me a simple example of a test?

Sure! Here's a basic example:

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

test('renders learn react link', () => {
  render(<MyComponent />);
  const linkElement = screen.getByText(/learn react/i);
  expect(linkElement).toBeInTheDocument();
});

What are some best practices for writing tests with it?

Some best practices include testing user interactions, keeping tests isolated, and using queries that resemble how users find elements.

How does it compare to Enzyme?

React Testing Library focuses on testing components as users would interact with them, while Enzyme allows for more detailed component testing and manipulation.
