NodeJS模型似乎不起作用

Question

试图单元测试我的小api，我需要测试保存错误和成功(已经注册，等等)。

下面是我的代码：models/auth.js

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var AuthSchema = Schema({
    id: String,
    user: String,
    password: String,
    origin: String,
});

//Export model
module.exports = mongoose.model('user', AuthSchema);

tests/api.test.js

const chai = require('chai');
const should  = chai.should;
const expect = chai.expect;
const assert = chai.assert;
/ Node Http Mocks
var httpMocks = require('node-mocks-http');

var util = require('util'),
    express = require('express'),
    bodyParser = require('body-parser'),
    validator = require('express-validator'),
    app = express();

var authController = require('../controllers/auth');

describe("Test AUTH Calls ", function() {
    var mongoHost = 'mongodb://localhost:27017/testingDB';

    // model
    var authModel = require('../models/auth.js');

    var Mongoose = require('mongoose').Mongoose;
    var mongoose = new Mongoose();

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

    // Generate a v1 UUID (time-based)
    const uuidV1 = require('uuid/v1');

    before(function(done) {
        mockgoose.prepareStorage().then(function() {
            mongoose.Promise = global.Promise;
            mongoose.connect(mongoHost, {
                keepAlive: true,
                reconnectTries: Number.MAX_VALUE,
                useMongoClient: true
            },function(err) {
                done(err);
            });
            mongoose.connection.on('connected', function(err) {
                if (err) {
                    console.log('Error on DB Connection: ', err);
                } else {
                    console.log('Db Connection opened!');
                }

            });
        });
    });

it("should warn that the user already exists", function(done) {
        var req = httpMocks.createRequest({
            method: 'GET',
            url: '/signup',
            body: {
                'username': 'tricky',
                'password': 'frasier'
            }
        });
        var res = httpMocks.createResponse();


        var userModel = new authModel({
            id: uuidV1(),
            username: req.body.username,
            password: req.body.password
        });

        userModel.save(function(err) {
            if (err) {
                console.log('Error while registering a user.', err.name);
            } else {
                console.log('User saved successfully.');
            }
        });

        var userN = req.body.username;

        // Check if already exists
        var myUser = null;
        authModel.findOne({
            username: userN,
        }, function(err, user) {
            if (err) {
                console.log('Error while verifying a user.', err.name);
            }
            if (user) {
                console.log('User exists.');
                myUser = user;
            }

        });

        authController.signup(req, res); // Will fail on user existing
        assert.equal(res.statusCode, 401);
        done();
    });

});

现在的问题是，第一个console.log说'DB连接打开了！‘，如果我填写了模型(userModel)的控制台日志，它会正确地记录，但我的问题正在保存。我不知道它是否保存，但没有从内部显示控制台日志，失败或成功。

有人能告诉我我做错了什么吗？

谢谢

Answer 1

对我来说，改变它是有效的：

var Mongoose = require('mongoose').Mongoose;
var mongoose = new Mongoose();

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

使用

var mongoose = require('mongoose');
var { Mockgoose } = require('mockgoose');

var mockgoose = new Mockgoose(mongoose);

您应该使用像下面这样的Schema关键字实例化new

var AuthSchema = new Schema({
    id: String,
    user: String,
    password: String,
    origin: String,
});

代码是异步的，因此很可能在console.log命令之前调用done()。您应该将一个回调放入另一个回调中，或者将代码转换为使用诺言。
