如何在React Native中进行测试？

npm install --save-dev @testing-library/react-native jest-dom @testing-library/jest-native

"jest": {
  "preset": "react-native",
  "setupFilesAfterEnv": ["@testing-library/jest-native/extend-expect"]
}

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

describe('Button', () => {
  it('renders correctly', () => {
    const { getByText } = render(<Button title="Submit" />);
    expect(getByText('Submit')).toBeTruthy();
  });

  it('calls onPress event handler', () => {
    const onPress = jest.fn();
    const { getByText } = render(<Button title="Submit" onPress={onPress} />);
    fireEvent.press(getByText('Submit'));
    expect(onPress).toHaveBeenCalled();
  });
});

npm test
