[spree-user] Rspec fails while testing spree Extension Routes

Hi guys,

My route file is as below.
==========================
Spree::Core::Engine.routes.prepend do
   namespace :admin do
     resources :question_categories
     resources :questions
   end
   match :faq, to: 'faqs#index', as: 'faq'
end

===========================

I'm testing against routes and i have created a file under
spec/routing/extension_route_spec.rb having this code.
==========================
require 'spec_helper'

describe Spree::FaqsController do
   it "routes to #index" do
     expect(:get=>'/faq').to route_to(:controller => "spree/faqs",:action =>
"index")
   end
end
=============================

But when i run my spec it gives me error "No Route matches"

Error:

1) Spree::FaqsController routes to #index
      Failure/Error: expect(:get=>'/faq').to route_to(:controller =>
"spree/faqs",:action => "index")
        No route matches "/faq"
      # ./spec/routing/spree_faq_route_spec.rb:5:in `block (2 levels) in
<top (required)>'

Why my extension routes are not accessible by rspec. I'm new to Spree. any
help?

Thanks.
