如何使用Jest/Enzyme测试React中的keydown事件？

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

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

describe('Component', () => {
  it('should handle keydown event', () => {
    const wrapper = shallow(<Component />);
    const event = { key: 'Enter' };
    wrapper.find('input').simulate('keydown', event);
    // 在这里编写断言，验证组件在接收到keydown事件后的行为
  });
});

npm test
