chai-http:无法读取在Assertion.<anonymous>处未定义的属性'headers‘

Question

当我在gitlab管道上运行我的单元测试时，我得到了这个错误，但它在我的本地环境下工作得很好：

TypeError: Cannot read property 'headers' of undefined
    at Assertion.<anonymous> (node_modules/chai-http/lib/http.js:175:19)
    at Assertion.propertyGetter (node_modules/chai/lib/chai/utils/addProperty.js:62:29)
    at Object.get (<anonymous>)
    at Object.proxyGetter [as get] (node_modules/chai/lib/chai/utils/proxify.js:98:22)

    at emitErrorCloseNT (internal/streams/destroy.js:74:3)
    at processTicksAndRejections (internal/process/task_queues.js:80:21)

这是我的单元测试文件架构：

tests/
├── Auth/
│   ├── AuthGetRegister.js
├── common.js
└── top.js

该应用程序也可以在docker环境下工作。

单元测试由以下命令运行：

./node_modules/.bin/mocha tests --reporter mocha-junit-reporter --reporter-options mochaFile=./test_results/test-results.xml --unhandled-rejections=strict

common.js：

let chai = require("chai");
let chaiHttp = require('chai-http');
let jwt = require('jsonwebtoken');
let fs = require('fs');

let privateKey = fs.readFileSync( __dirname + '/../RSA/jwtRS256.key');
let options = {
    server: "http://localhost:3000/api",
    jwt: jwt.sign({ userId: "fa76aff7-83e7-4ec2-b3e7-79d1629577b0" }, privateKey, { expiresIn: '3m',  algorithm: 'RS256' })
};

chai.use(chaiHttp);

exports.options = options;
exports.chai = chai;
exports.assert = chai.assert;
exports.expect = chai.expect;

top.js：

var common = require("./common");

/*
**  Auth
*/

describe("GET /api/auth/register", function () {
    require('./Auth/AuthGetRegister');
});

AuthGetRegister.js：

let common = require("../common");
let options = common.options;
let chai = common.chai;
let expect = common.expect;

it('it should return status 200 with a list of pathologies', (done) => {
    chai.request(options.server)
        .get('/auth/register')
        .end((err, res) => {
            expect(res).to.be.json;
            expect(res).to.have.status(200);
            done();
        });
});

我以AuthGetRegister为例，但我的所有单元测试都得到了相同的错误。

我已经尝试了建议的here的变通方法，但它不起作用。

这是我的gitlab配置的一个问题。单元测试是在服务器完全运行之前运行的。

我添加了一个wait-for-it脚本来等待服务器运行，然后运行单元测试。
