如何使用sinon.js和promise来存根https.request response.pipe以及可能的路径？

const sinon = require('sinon');
const https = require('https');

// 创建一个存根来模拟 https.request
const requestStub = sinon.stub(https, 'request');

// 创建一个模拟的响应对象
const mockResponse = {
  statusCode: 200,
  headers: { 'content-type': 'application/json' },
  pipe: sinon.spy()
};

// 创建一个 Promise 来模拟异步请求
const mockRequestPromise = new Promise((resolve, reject) => {
  resolve(mockResponse);
});

// 配置存根返回模拟的 Promise
requestStub.callsFake((options, callback) => {
  return mockRequestPromise;
});

// 使用存根进行测试
const testFunction = (url) => {
  return new Promise((resolve, reject) => {
    https.request(url, (res) => {
      let data = '';
      res.on('data', (chunk) => {
        data += chunk;
      });
      res.on('end', () => {
        resolve(data);
      });
    }).on('error', (err) => {
      reject(err);
    }).end();
  });
};

testFunction('https://example.com')
  .then((data) => {
    console.log('Response data:', data);
  })
  .catch((err) => {
    console.error('Error:', err);
  });

// 验证存根的使用情况
console.log(sinon.assert.calledOnce(requestStub));
console.log(sinon.assert.calledOnce(mockResponse.pipe));
