 If you're using RSpec and want the helpers automatically included within all +describe+ blocks, add a file called spec/support/devise.rb with the following contents:
 
   RSpec.configure do |config|
-    config.include Devise::TestHelpers
+    config.include Devise::TestHelpers, :type => :controller
   end
 
 Do not use such helpers for integration tests such as Cucumber or Webrat. Instead, fill in the form or explicitly set the user in session. For more tips, check the wiki (http://wiki.github.com/plataformatec/devise).
