在try/catch中使用async/await方法的Jest/酶测试反应组件

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

import { fetchData } from '../yourAsyncUtils';

describe('YourComponent', () => {
  it('should render data correctly when fetchData resolves', async () => {
    jest.spyOn(window, 'fetchData').mockResolvedValue('mocked data');
    const wrapper = shallow(<YourComponent />);
    await wrapper.instance().fetchData();

    expect(wrapper.state().data).toEqual('mocked data');
  });

  it('should handle error when fetchData rejects', async () => {
    jest.spyOn(window, 'fetchData').mockRejectedValue(new Error('mocked error'));
    const wrapper = shallow(<YourComponent />);
    await wrapper.instance().fetchData();

    expect(wrapper.state().error).toEqual('mocked error');
  });
});
