How do I use React Native Testing Library?

You can start by installing the library using npm or yarn. Would you like to see a basic example?

Yes, please show me a basic example.

Sure! Here's a simple test for a button component:

import { render, fireEvent } from '@testing-library/react-native';
import MyButton from './MyButton';

test('it calls the onPress function when pressed', () => {
  const onPressMock = jest.fn();
  const { getByText } = render(<MyButton onPress={onPressMock} />);
  fireEvent.press(getByText('Press me'));
  expect(onPressMock).toHaveBeenCalled();
});

What other features does it offer?

It provides utilities for querying elements, simulating user interactions, and asserting on component behavior. Would you like to know more about specific features?
