Rspec testing in rails3

Hi,

I have a Queues controller and and QueueItems controller in my rails application. In routes I have defined as below `match 'queues/:queue_id/next', :to=> 'queueitems#next'` In my QueueItems Controller I have a next action and it assigns an instance variable.

    def next     @queue = "Regular"     #other stuffs related to regular     end

How do I test this in Rspec. I am pretty very new to Rspec. Please help. I tried like the below

    describe "next " do       it "routes /queues/:queue_id/next" do         { :get => "/queues/regular_queue/next" }.should route_to(           :controller => "queue_items",           :action => "next",           :queue_id => "regular_queue",           :format => "json"             )         assigns(:queue).should_not be_nil         expect(response).to be_success       end

But it is not at all coming inside my next action in controller.
