我的回调没有被调用

Question

这里我正在尝试测试我的api但是在执行期间没有调用回调函数并且一直没有失败地返回。

const express = require('express')
const app = express();
const nconf = require('nconf');
const request = require('request');
var index = require('../index')
var querystring = require('querystring');


describe("Auth", function () {
console.log("Auth");

var form = {
    "email":"a@a.com",
    "password":"123456",
    "name":"aleem",
    "mobile":"12345678903",
    "country":"india",
    "state":"telangana",
    "city":"hyderabad"
}


var formData = querystring.stringify(form);

// Creating account with existing user data
it ("Returns statusText false", function (done) {
    var url = 'http://http://localhost:5000/api/auth/signup/';
    var headers = {
        'Content-Type' : 'application/x-www-form-urlencoded'
    };
    request.post({ url: url, form: formData, headers: headers }, function (e, r, body) {
        // callback body
        console.log(r.statusCode+'ka');
        expect(r.statusText).toBe('false');
        done() ;
    });
});
});

在执行期间，未调用回调函数。
