如何使用Mocha -Enzyme和nock进行测试，当响应类型为数组缓冲区时，使用axios.get获取文件？

npm install mocha enzyme nock axios --save-dev

yarn add mocha enzyme nock axios --dev

const axios = require('axios');
const { expect } = require('chai');
const { mount } = require('enzyme');
const nock = require('nock');

// 引入需要测试的组件或函数
const MyComponent = require('./MyComponent');

describe('MyComponent', () => {
  beforeEach(() => {
    // 模拟axios.get请求，并返回一个包含文件内容的数组缓冲区
    nock('http://example.com')
      .get('/file')
      .reply(200, new Buffer([1, 2, 3]));
  });

  it('should render file content', async () => {
    // 渲染组件
    const wrapper = mount(<MyComponent />);

    // 等待异步操作完成
    await new Promise(resolve => setTimeout(resolve, 100));

    // 断言组件渲染的文件内容是否正确
    expect(wrapper.text()).to.equal('1,2,3');
  });
});
