What is React Native Testing Library?

React Native Testing Library is a testing utility for React Native applications that encourages good testing practices.

How does it differ from Jest?

While Jest is a testing framework, React Native Testing Library is built on top of it to provide utilities specifically for testing React Native components.

Can you give me an example of how to use it?

Sure! You can use it to render a component and then query it for elements. For example:

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

test('it renders correctly', () => {
  const { getByText } = render(<MyComponent />);
  expect(getByText('Hello World')).toBeTruthy();
});

What are some best practices for testing with it?

Some best practices include testing user interactions, avoiding implementation details, and keeping tests focused on behavior.
