Тест интеграции rspec с devise выдает ошибку NoMethodError

У меня есть аналогичная ошибка, размещенная здесь, но все не решит мою проблему.

Мой файл 'spec / request / news_controller_spec.rb' выглядит так:

require 'spec_helper'

describe "NewsController" do

  include Devise::TestHelpers

  describe "GET /news" do

    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      @user.confirm!
      sign_in @user
    end

    it "after login should show the latest news an screen" do
      page.should have_content("News")
    end
  end
end

Если я запускаю тест, я получаю:

Failures:

  1) Campaigns GET /news works!

Я выполнил инструкции на https://github.com/plataformatec/ devise / wiki / How-To% 3a-Controllers-and-Views-tests-with-Rails-3-% 28and-rspec% 29 и другие подобные вопросы здесь, но я не могу найти решение.

Я использую следующий гемсет:

• capybara (1.1.2)
• devise (1.5.3)
• factory_girl_rails (1.6.0)
• rails (3.2.0, 3.1.1)
• rspec (2.8.0)
• rspec-core (2.8.0)
• rspec-ожидание (2.8.0)
• rspec-mocks (2.8.0)
• rspec-rails (2.8 .1)

и некоторые другие драгоценности.

Кто-нибудь может мне помочь, запустить мои интеграционные тесты с авторизованным пользователем. В этом случае новости отображаются, только если пользователь авторизован.

Спасибо.
