我在测试时无法使用我的范围变量

Question

我无法在我的考试中使用我的变量$ scope.films与业力，我不知道我在哪里失败：

filmsService.js：

(function () {
    'use strict';

    var filmsServices = angular.module('filmsServices', ['ngResource']);

    filmsServices.factory('Films', ['$resource',
      function ($resource) {
          return $resource('Controllers/films/', {}, {
              query: { method: 'GET', params: {}, isArray: true }

          });
      }]);
})();

filmsController.js：

(function () {
    'use strict';

    angular
        .module('filmsApp')
        .controller('filmsController', filmsController);

    filmsController.$inject = ['$scope' , 'Films']; 
    function filmsController($scope, Films) {
        $scope.films = Films.query();
    }
})();

FilmsController.cs：

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.AspNet.Mvc;
using mvc_template.Models;

// For more information on enabling Web API for empty projects, visit http://go.microsoft.com/fwlink/?LinkID=397860

namespace mvc_template.API.Controllers
{
    [Route("api/[controller]")]
    public class FilmsController : Controller
    {
        // GET: api/values
        [HttpGet]
        public IEnumerable<Film> Get()
        {
            return new List<Film>
            {
                new Film {Id=1, Title="Star wars",Director="Lucas"  },
                new Film {Id=1,Title="king Kong", Director="Jackson" },
                new Film {Id=1,Title="Memento", Director="Nolan" }
            };
        }

    }
}

app.js：

(function () {
    'use strict';

    angular.module('filmsApp', [
        'filmsServices'
    ]);
})();

最后是不通过的测试：

describe('filmsController function', function () {

    describe('filmsController', function () {
        var $scope,$ctrl;

        beforeEach(module('filmsApp'));

        beforeEach(inject(function ($rootScope, $controller) {
            $scope = $rootScope.$new();
            $ctrl = $controller('filmsController', { $scope: $scope });
            console.log($ctrl);
            console.log("$ctrl.$scope : " + $ctrl.$scope);
        }));


        it('should create "films" model with 3 films', function () {
            console.log($scope);
            console.log("$scope.films[1] : "+$scope.films[1]);
            expect($scope.films.length).toBe(3);
        });
    });
});   

业力归来于此：
