rspec integration test with devise throws NoMethodError error

问题

I have a similar error posted here, but all will not fix my problem.

My file 'spec/request/news_controller_spec.rb' looks like:

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

If I run the test I'll get:

Failures:

  1) Campaigns GET /news works!

I followed instructions on https://github.com/plataformatec/devise/wiki/How-To%3a-Controllers-and-Views-tests-with-Rails-3-%28and-rspec%29 and other similar Questions here, but I can't find a solution.

I'm using following gemset:

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-expectations (2.8.0)
rspec-mocks (2.8.0)
rspec-rails (2.8.1)

and some other gems.

Can anybody help me, getting my integration tests with a logged in user get running. In this case the news are only displayed, if a user is logged in.

Thanks.

I actually had the same exact problem, and after googling a little bit I found that including Warden::Test::Helpers directly was a more concise solution for request specs, since it programmatically signs in/out users just like this:

# spec/support/request_helpers.rb
require 'spec_helper'
include Warden::Test::Helpers

module RequestHelpers
  def create_logged_in_user
    user = Factory(:user)
    login(user)
    user
  end

  def login(user)
    login_as user, scope: :user
  end
end

In short, just include Warden::Test::Helpers and then use the login_as <your_user> method and that's it!
