使用酶和Jest测试React : container :目标容器不是DOM元素

import { mount } from 'enzyme';
import MyComponent from './MyComponent';

describe('MyComponent', () => {
  let container;

  beforeEach(() => {
    container = mount(<MyComponent />);
  });

  afterEach(() => {
    container.unmount();
  });

  it('should render correctly', () => {
    // 断言组件是否正确渲染
    expect(container.find('.my-component').length).toBe(1);
  });

  it('should update state on button click', () => {
    // 模拟按钮点击事件
    container.find('button').simulate('click');

    // 断言状态是否正确更新
    expect(container.state().count).toBe(1);
  });
});
