如何对React中封装的react-router-dom withRouter()组件进行Jest /酶测试？

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

import React from 'react';
import { shallow } from 'enzyme';
import { withRouter } from 'react-router-dom';

// 导入要测试的组件
import App from './App';

// 创建一个包装了withRouter的组件
const WrappedComponent = withRouter(App);

describe('App', () => {
  it('renders without crashing', () => {
    shallow(<WrappedComponent />);
  });

  it('renders the correct title', () => {
    const wrapper = shallow(<WrappedComponent />);
    const title = wrapper.find('h1').text();
    expect(title).toEqual('My App');
  });

  it('renders a link to the home page', () => {
    const wrapper = shallow(<WrappedComponent />);
    const link = wrapper.find('Link[to="/"]').first();
    expect(link.exists()).toBeTruthy();
  });
});
