title: Check if a user is signed out in devise
body: <p>I'm trying to check if an administrator is signed out in an Rspec test. However the usual signed_in? method can't be seen from rspec and isn't part of the RSpec Devise Helpers.</p>
  
  <p>Something like this is what i have in place</p>
  
  <pre><code>before (:each) do
          @admin = FactoryGirl.create(:administrator)
          sign_in @admin
        end
  
  
        it "should allow the admin to sign out" do
          sign_out @admin
          #@admin.should be_nil
          #@admin.signed_in?.should be_false
          administrator_signed_in?.should be_false
        end
  </code></pre>
  
  <p>Is there anothe way to check the session of the administrator and see if he's actually signed in or not?</p>
