TypeError:无法读取未定义的supertest的属性"address"

Question

我需要一些帮助来解决我在nodejs代码上测试的问题.我正在使用摩卡和超级.我对supertest中的实现感到困惑.我不知道解决了.我正在尝试自动下载文件.

`describe('GET /entry/:entryId/file/:id/download', function(){
 it('should pass download function', function(done){
   this.timeout(15000);
   request(app.webServer)
  .get('/entry/543CGsdadtrE/file/wDRDasdDASAS/download')
  .set('Authorization', 'Bearer eyJ0eXAiOiJKV1QiLCJhbGco')
  .expect(200)
  .end(function(err, res){
  if (err) return done(err);
  console.log(err, res);
  done();
 });
});
});

在测试快速应用时,我收到了来自摩卡的类似错误.错误全文:

0 passing (185ms)
2 failing

1) loading express responds to /:
 TypeError: app.address is not a function
  at Test.serverAddress (test.js:55:18)
  at new Test (test.js:36:12)
  at Object.obj.(anonymous function) [as get] (index.js:25:14)
  at Context.testSlash (test.js:12:14)

2) loading express 404 everything else:
 TypeError: app.address is not a function
  at Test.serverAddress (test.js:55:18)
  at new Test (test.js:36:12)
  at Object.obj.(anonymous function) [as get] (index.js:25:14)
  at Context.testPath (test.js:17:14)

我通过将它添加到我的express server.js来修复它,即导出服务器对象

module.exports = app

面对此错误的Typescript用户检查两件事:

1. 快递服务器应该有module.exports = app(感谢@Collin D)
2. 使用import * as app from "./app"
   而不是错误 import app from "./app"
