Угловые услуги не определены в beforeEach в Карме

У меня есть угловое приложение, использующее Jasmine и Karma для тестирования.

Это мой класс тестирования:

var data = require('./user.mock.js');

describe('Service: UserService', function () {
  var ServerUrl;
  var httpBackend;
  var userService;

  beforeEach(angular.mock.module('myModule'));

  beforeEach(angular.mock.inject(function (_userService_, $httpBackend, _ServerUrl_) {
    userService = _userService_;
    httpBackend = $httpBackend;
    ServerUrl = _ServerUrl_;
  }));

  describe('when get the active users from backend', function () {
    // given
    beforeEach(function () {
      httpBackend
        .whenGET(ServerUrl + '/users')
        .respond(angular.copy(data.activeUsers));
    });

    it('should return the list of active users', function () {
      var expectedUsers = angular.copy(data.activeUsers);
      expectedUsers[0].profilePicture = ServerUrl + '/pictures/' + expectedUsers[0].id + '/small/show';
      expectedUsers[1].profilePicture = ServerUrl + '/pictures/' + expectedUsers[1].id + '/small/show';

      userService
        .listUsers()
        .then(function(users) {
          expect(users).toEqual(expectedUsers);
        });

      httpBackend.flush();
    });
  });

И это моя карма conf:

  config.set({

};

Когда я запускаю тест кармы из командной строки, внедренные службы не распознаются. Я подозреваю, что функция инъекции не вызывается в методе beforeEach, но я не уверен. Я испытываю неопределенность в тестах, как будто переменная никогда не получала никакого значения.

Можете ли вы, ребята, помочь мне?
