How do I mock the dependency of the things under test?

bullet_view.js

define(["game/thing_view"], function(ThingView) {
  return function(THREE, bullet) {
    var _this = new ThingView(THREE, bullet, "/public/img/tank_bullet.png")

    return _this;
  }
});

testzor.coffee

requirejs = require('../spec_helper').requirejs
three = require('../stubs/three').three

ThingView = jasmine.createSpy('ThingView')
requirejs.define "game/thing_view", [], () ->
  return ThingView

requirejs ["game/bullet_view", "game/bullet"], (BulletView, Bullet) ->
  describe "bullet view", ->
    bullet = new Bullet()

    it "should create a thing view", ->
      view = new BulletView(three, bullet)
      expect(ThingView).toHaveBeenCalled()

    it "should use the bullet image", ->

requirejs.undef("game/thing_view")
