rspec users - Jul 2011 - can't access route variables

I''m testing methods in my ApplicationController using anonymous
controller
class (not sure if that''s relevant).  I''ve somehow broken
something such
that I do not have access to the routing variables that rails generates.

So rather than having something like ''response.should redirect_to
new_user_session_path'' I''m having to go with
''response.should redirect_to
''/users/sign_in''

I''ve created a new project to check if I messed anything in spec_helper
or
something else, and I''ve been unable to reproduce outside of my current
project.  I can access the route variables from other controller spec
classes, but not from the application_controller_spec.

Can anyone point me at where to look to start troubleshooting this?

Rails 3.0.5
$ gem list | grep rspec
rspec (2.5.0)
rspec-core (2.5.2)
rspec-expectations (2.5.0)
rspec-mocks (2.5.0)
rspec-rails (2.5.0)


Code snippets
/app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  protect_from_forgery

  def require_bar
    if
!user_signed_in?

      redirect_to new_user_session_path
      return
    end
   # check for bar here
  end
end

/spec/controllers/application_controller_spec.rb
require ''spec_helper''

describe ApplicationController do
  describe "#require_bar" do
    controller do
      before_filter :require_bar
      def index
        render :text => "", :status => 200
      end
    end

    context "when not signed in" do
      before :each do
        controller.stub(:user_signed_in?).and_return(false)
      end
      it "should fail gracefully by redirecting to log in" do
        get :index
        # This works
        response.should redirect_to ''/users/sign_in''
        # this causes: undefined local variable or method
`new_merchant_session_path'' for
#<RSpec::Core::ExampleGroup::Nested_1::Nested_2::Nested_1:0x000001034cd160>
        # response.should redirect_to new_user_session_path
      end
    end
  end

RSpec''s anonymous controller does not use your routes. If you look at
how the controller method is implemented[1], you''ll see the routes
being replaced with just the anonymous resources.

You can do something similar in a before block in your spec. For example:

describe ApplicationController do
? describe "#require_bar" do
??? controller do
????? before_filter :require_bar
????? def index
??????? render :text => "", :status => 200
????? end
??? end

    before do
      @routes.draw do
        resources :anonymous # for all other specs to keep working
        resources :user_sessions # this makes new_user_session_path available
      end
    end

??? context "when not signed in" do
????? before :each do
??????? controller.stub(:user_signed_in?).and_return(false)
????? end
????? it "should fail gracefully by redirecting to log in" do
??????? get :index
??????? response.should redirect_to new_user_session_path
????? end
??? end
? end
end

Hope that helps,
Mike
