How do I test my React Native app using Jest?
To test your React Native app with Jest, first ensure you have Jest installed. You can do this by running npm install --save-dev jest
.
What types of tests can I write for my app?
You can write unit tests for individual components, integration tests for component interactions, and snapshot tests to track UI changes.
Can you show me an example of a simple test?
Sure! Here's a simple test for a button component:
import React from 'react';
import { render } from '@testing-library/react-native';
import MyButton from './MyButton';
test('renders correctly', () => {
const { getByText } = render(<MyButton />);
expect(getByText('Click Me')).toBeTruthy();
});
