How can I automate tests in React Native?

You can automate tests in React Native using tools like Jest for unit testing and Detox for end-to-end testing.

What is Jest and how do I set it up?

Jest is a JavaScript testing framework. To set it up, install it via npm and create a configuration file.

Can you give me an example of a test case using Jest?

Sure! Here's a simple test case:

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

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

What about Detox? How does it work?

Detox is an end-to-end testing framework for React Native. It simulates user interactions and checks the app's behavior.
