如何测试React元素是否包含酶中的文本？

npm install enzyme enzyme-adapter-react-16 --save-dev

yarn add enzyme enzyme-adapter-react-16 --dev

import { shallow, configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

configure({ adapter: new Adapter() });

import React from 'react';
import { shallow, configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

configure({ adapter: new Adapter() });

describe('MyComponent', () => {
  it('should contain the text "Hello, World!"', () => {
    const wrapper = shallow(<MyComponent />);
    const text = wrapper.text();
    expect(text).toContain('Hello, World!');
  });
});
