Ruby-on-rails – How to test controllers with nested routes using rspec

I create controller with InherritedResource

class AppsController < InheritedResources::Base
  belongs_to :company

  # Devise
  before_filter :login_or_oauth_required
  # CanCan
  load_and_authorize_resource
end

and try to test it with Rspec by this method

require "spec_helper"

include Devise::TestHelpers

describe AppsController do
  before(:each) do
    @company_1 = Factory.build(:company)
    application_1 = Factory.create(:application, :company => @company_1)
    application_2 = Factory.create(:application, :company => @company_1)
    application_3  = Factory.create(:application, :company => @company_1)    
    @company_2 = Factory.build(:company)

    @user_1   = Factory.create(:user)
    role_1    = Factory.create(:publisher_role, :company => @company_1) 
    profile_1 = Factory.create(:profile, :company => @company_1, :user => @user_1, :roles => [role_1])
  end

  describe "index action" do
    it "user_1 should have 3 applications from company_1" do
      sign_in @user_1
      params = {"company_id"=>"1"}
      get :index
      assigns[:apps].should have(3).items
    end
  end
end

The result is

Failure/Error: get :index
     ActionController::RoutingError:
       No route matches {:controller=>"apps"}

How to tell Rspec to "Get" in to my nested route

My routes

  resources :companies do
    resources :apps do
      resources :shelves do
        resources :publications
      end
    end
  end
