React Native Testing -如何在快照之外测试和测试组件？

import React from 'react';
import TestRenderer from 'react-test-renderer';
import MyComponent from './MyComponent';

test('renders correctly', () => {
  const testRenderer = TestRenderer.create(<MyComponent />);
  const json = testRenderer.toJSON();
  expect(json).toMatchSnapshot();
});

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

test('renders correctly', () => {
  const { getByTestId } = render(<MyComponent />);
  const button = getByTestId('my-button');
  expect(button).toBeTruthy();
});

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

test('renders correctly', () => {
  const { getByTestId } = render(<MyComponent />);
  const button = getByTestId('my-button');
  expect(button).toBeTruthy();
});

import React from 'react';
import { shallow } from 'enzyme';
import MyComponent from './MyComponent';

test('renders correctly', () => {
  const wrapper = shallow(<MyComponent />);
  expect(wrapper.find('.my-button')).toHaveLength(1);
});
