undefined method `authenticate?'

If you are getting this error:

ActionView::Template::Error: undefined method `authenticate?' for nil:NilClass

in your call to Devise’s user_signed_in? or similar, you probably forgot to add this:

class ActionController::TestCase
  include Devise::TestHelpers
end

at the bottom of the test_helper.rb file. Not that that would ever happen to me…

    Thank you! Apparently, Ruby class declarations are additive. The ActionController::TestCase class is declared in both the actionpack gem and your app’s test_helper.rb. However, both declarations are put together to form the class implementation as opposed to some languages where an error would occur at compile or interpretation time due to ambiguous redeclaration.
