How can I test this angular promise?

I have the following code:

Controller

angular.module('myApp').controller 'dashboardController', (User) ->

  User.find('current').then (data) =>
    @currentUser = data

User factory

angular.module('myApp').factory 'User', ($resource) ->

  $resource = $resource '/api/v1/users/:id'

  @find = (id) ->
    $resource.get(id: id).$promise

  return this

Controller test

describe 'dashboardController', ->
  beforeEach module 'myApp'

  beforeEach inject ($controller, User, $rootScope, $q) ->
    @dashboardController = $controller 'dashboardController'
    @User                = User
    @$scope              = $rootScope
    @$q                  = $q

  afterEach ->
    @dashboardController = {}
    @User                = {}
    @$scope              = {}
    @$q                  = {}

  beforeEach ->
    @deferredSuccess = @$q.defer()
    @deferredSuccess.resolve({foo: 'bar'})

    spyOn(@User, 'find').and.returnValue(@deferredSuccess.promise)

  it 'should call User.find()', ->
    @$scope.$apply()

Test failure message...

Error: Unexpected request: GET /api/v1/users/current
