var chai = require('chai');
var chaiHttp = require('chai-http');
var should = chai.should();
var expect = require("chai").expect;
var testData = require('./testData');
var apiUrl = require('./apiUrl');

chai.use(chaiHttp);


var Mongoose = require('mongoose').Mongoose,
      mongoose = new Mongoose,
      Mockgoose = require('mockgoose').Mockgoose,
      mockgoose = new Mockgoose(mongoose);

var server = require('../../../app');
var productFamily = require('../../../api/models/referenceData/productFamilyModel');

      before(function (done) {
            mockgoose.helper.reset().then(function () {
                  done();
            });
      });
      //Test1
      it("isMocked", function (done) {
            expect(mockgoose.helper.isMocked()).to.be.true;
            done();
      });

           it("should create productFamily", function (done) {
            prod_common_cases.create_prod_family(done);
            });

我们需要设置timeout为it异步。简单地放在this.timeout(222222)每个测试中。即在每个it功能中。

 it("should create product Family ", function (done) {
     this.timeout(222222);     
     prod_common_cases.create_prod_family(done);
 });
