Подделка структуры объектов Google Maps с помощью JavaScript для модульных тестов

Объекты API Карт Google используются следующим образом: google.maps."Constructor" кажется.

Я хочу подделать вызовы, перечисленные ниже...

//var map = new google.maps.Map(value);
//var fireStationBound = new google.maps.LatLng(val,val);
//var bounds = new google.maps.LatLngBounds(boundary, boundary);
//var markerFireStation = new google.maps.Marker(val);
//var waterstationLayer = new google.maps.KmlLayer(val);
//map.mapTypes.set();

... с кодом ниже...

 $(document).ready(function() {

   function google() {

     /* todo: Setup for every constructor a test function returning the test data */

     function LatLng(value) {

     }

     function LatLngBounds(value,value) {

     }

     function Marker(value) {

     }

     function Map(value) {

     }

     function KmlLayer(value) {

     }

     var maps = {
                  maps: {
                          LatLng: LatLng,
                          LatLngBounds: LatLngBounds,
                          Marker: Marker,
                          Map: Map,
                          KmlLayer: KmlLayer
                        }
                };
                return maps;
     }

     **// Works**
     var google = new google();    
     var bound = new google.maps.LatLng(10);
     var bounds = new google.maps.LatLngBounds(10,20);
     var marker = new google.maps.Marker(10);
     var layer = new google.maps.KmlLayer(10);
     var map = new google.maps.Map(10);
     **// Doesn't Work **
     map.mapTypes.set();
});

Как я могу подделать этот код Google...

map.mapTypes.set();

... который возвращается вызовом...

var map = google.maps.Map(val);

Как должен выглядеть мой JavaScript, чтобы набрать map.mapTypes.set() и, наконец, вызывается функция set?

Я просто хочу подделать объекты Google, которые я использую в своем коде для модульных тестов.

Здесь наш заглушка Google Maps для v3.19.18. Это было первоначально написано на CoffeeScript, но я провел его через js2coffee, и здесь была сырая реализация Javascript. Я добавил mapTypes.set() для вас.
