猫鼬mongodb保存子文件混乱吗？ 摩卡测试未完成（）

Question

I'm trying to write some tests in mocha to save a document and some subdocuments inside of the beforeEach method, but it appears to never reach done and then proceeds to time out.

Here is the schema:

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

var LatLng = new Schema({
  id: Schema.ObjectId,
  created_at: Date,
  accuracy: {
    type: Number,
    required: true
  },
  latitude: {
    type: Number,
    required: true
  },
  longitude: {
    type: Number,
    required: true
  }
});
LatLng.pre('save', function(next){
  if(!this.created_at)
    this.created_at = new Date();
});

var Walk = new Schema({
  id: Schema.ObjectId,
  created_at: Date,
  updated_at: Date,
  description: String,
  elapsedTime: Number,
  distance: Number,
  waypoints: [LatLng],
  _user: {
    type: Schema.ObjectId,
    ref: 'User',
    required: true
  }
});

Walk.pre('save', function(next){
  var now = new Date();
  this.updated_at = now;
  if(!this.created_at)
    this.created_at = now;
  next();
});

Walk.pre('update', function(next){
  this.updated_at = new Date();
});

Walk.pre('findOneAndUpdate', function(next){
  this.updated_at = new Date();
});

Walk.pre('findByIdAndUpdate', function(next){
  this.updated_at = new Date();
});

module.exports = mongoose.model('Walk', Walk);

Here is the beforeEach :

beforeEach(function(done){
      var _this = this;
      //create temporary user
      var userData = { username: 'bob', password: 'password123' };
      var user = new User(userData)
      .save(function(err, user){
        if(err) done(err);

        _this.user = user;

        //login with temporary user
        req.post('/login')
        .send(userData)
        .end(function(err, res){
          if(err) done(err);

          //create temporary models
          var walk1 = new Walk({
            description: 'description1',
            elapsedTime: 10000,
            distance: 5000,
            _user: res.body.user._id,
            waypoints: [
              {"accuracy":11, "latitude":44.06523257, "longitude":-123.06101363},
              {"accuracy":12, "latitude":44.06525829, "longitude":-123.06100709},
              {"accuracy":11, "latitude":44.06523424, "longitude":-123.06099261},
              {"accuracy":11, "latitude":44.0652201, "longitude":-123.06097669}
            ]
          });

          var walk2 = new Walk({
            description: 'description1',
            elapsedTime: 10000,
            distance: 5000,
            _user: res.body.user._id,
            waypoints: [
              {"accuracy":11, "latitude":44.06523424, "longitude":-123.06099261},
              {"accuracy":11, "latitude":44.0652201, "longitude":-123.06097669},
              {"accuracy":11, "latitude":44.06521917,"longitude":-123.06098176}
            ]
          });

          var walk3 = new Walk({
            description: 'description1',
            elapsedTime: 10000,
            distance: 5000,
            _user: res.body.user._id,
            waypoints: [
              {"accuracy":6, "latitude":44.06528592, "longitude":-123.06087405},
              {"accuracy":4, "latitude":44.06528038, "longitude":-123.06088851},
              {"accuracy":4, "latitude":44.06528185, "longitude":-123.06088036}
            ]
          });

          //save temporary models
          walk1.save(function(err, walk){
            console.log('got here'); // <--Never gets here
            if(err) return done(err);
            _this.walk1 = walk1;
            console.log(walk);

            walk2.save(function(err, walk){
              if(err) return done(err);
              _this.walk2 = walk2;
              console.log(walk);

              walk3.save(function(err, walk){
                if(err) return done(err);
                _this.walk3 = walk3;
                console.log(walk);
                done(); // <---Done is called here, so it's not this...
              });
            });
          });

        });
      });
    });

Here is the test I'm trying to write:

it.only('should create a new walk', function(done){
  var _this = this;
  var walk = {
    description: "this is a description",
    elapsedTime: 100000,
    distance: 5000,
    waypoints:
      [{ "accuracy":11, "latitude":44.06523257, "longitude":-123.06101363 },
      { "accuracy": 12, "latitude": 44.06525829,"longitude": -123.06100709},
      { "accuracy": 21, "latitude":44.06521917, "longitude":-123.06098176 }]
    };
    var query = { description: walk.description};
    req.post('/login')
      .send(userData)
      .end(function(err, res){
        if(err) return done(err);
        req.post('/walks')
          .send(walk)
          .expect(200)
          .end(function(err, res){
            if(err) return done(err);
            res.body.success.should.equal(true);
            Walk.findOne(_this.query, function(err, walk){
              if(err) return done(err);
              walk.should.not.be.null();
              walk.description.should.match(_this.walk.description);
              walk.elapsedTime.should.equal(_this.walk.elapsedTime);
              walk.distance.should.equal(_this.walk.distance);
              walk.waypoints.should.be.type('object');
              done();
            });
          });
        });
      });

Sorry about the formatting, it got screwed up while copy and pasting it.

I'm confused as to what the problem is...all I get when I try to run the test is it says that the beforeEach has timed out and to call done . But done is being called, therefor I assume something is going on while it's actually saving, but there is no errorsbeing produced. I've tried setting mochas timeout as high as 30 seconds to see if it was mongodb lagging, to no avail. Totally confused at the moment, hoping one of you amazing people on SO can rescue me :)

Thanks for taking the time to read my post and help out!

Update :

So I put a few console.log() statements inside of Walk.pre('save') , as well as in LatLng.pre('save') and it appears that Walk.pre('save') never getting called, but the LatLng.pre('save') is...

Update2:

Tried putting some console.log() statments inside of the post('save') functions and it appears they never get called. LatLng.pre('save') is getting called and then I'm thinking it's just sitting there hanging...?

Answer 1

Wow, can't believe I missed that. Simply forgot to call next in my LatLng.pre('save') ...
