Почему методы RSpec, "get", "post", "put", "delete" работают в спецификации контроллера в драгоценном камне (или вне Rails)?

Я не новичок в Rails или Rspec, но я новичок в создании драгоценных камней. Когда я тестирую свои контроллеры, методы REST "get", "post", "put", "delete" дают мне ошибку метода undefined.

Ниже вы найдете код, но если вы предпочитаете его видеть в пасте, нажмите здесь.

Спасибо!

Здесь мой spec_helper:

$LOAD_PATH.unshift(File.dirname(__FILE__))
$LOAD_PATH.unshift(File.join(File.dirname(__FILE__), '..', 'lib'))
require 'rubygems'
require 'active_support' unless defined? ActiveSupport # Need this so that mattr_accessor will work in Subscriber module
require 'active_record/acts/subscribable'
require 'active_record/acts/subscriber'
require 'action_view'
require 'action_controller' # Since we'll be testing subscriptions controller
#require 'action_controller/test_process'
require 'spec'
require 'spec/autorun'


# Need active_support to user mattr_accessor in Subscriber module, and to set the following inflection
ActiveSupport::Inflector.inflections do |inflect|
  inflect.irregular 'dorkus', 'dorkuses'
end                     

require 'active_record' # Since we'll be testing a User model which will be available in the app

# Tell active record to load the subscribable files
ActiveRecord::Base.send(:include, ActiveRecord::Acts::Subscribable)
ActiveRecord::Base.send(:include, ActiveRecord::Acts::Subscriber)


require 'app/models/user' # The user model we expect in the application
require 'app/models/person'
require 'app/models/subscription'
require 'app/models/dorkus'
require 'app/controllers/subscriptions_controller' # The controller we're testing
#... more but I think irrelevant

Мои подписки_спец:

  load_schema

  describe ", when only subscribable params are passed" do
    it "should list all the subscriptions of the subscribable object"

      d2 = Dorkus.create
      d1.subscribe! u
      d2.subscribe! u

      get :index, {:subscriber_type => "User", :subscriber_id => u.id}
      assigns[:subscriptions].should == u.subscriptions

Мой контроллер подписок:
