Reactjs单元测试:如何覆盖useEffect钩子中的代码？使用Jest和酶

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

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

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

import React, { useEffect } from 'react';

const ExampleComponent = () => {
  useEffect(() => {
    console.log('useEffect code');
  }, []);

  return <div>Example Component</div>;
};

export default ExampleComponent;

import React from 'react';
import { mount } from 'enzyme';
import ExampleComponent from './ExampleComponent';

describe('ExampleComponent', () => {
  it('should call useEffect code', () => {
    const spy = jest.spyOn(console, 'log');
    mount(<ExampleComponent />);
    expect(spy).toHaveBeenCalledWith('useEffect code');
    spy.mockRestore();
  });
});

npm test
