ruby-on-rails – Rspec路由规范失败,param id被反转？

require "spec_helper"

describe GameController do
  describe "routing" do

    game = FactoryGirl.create(:game)

    it "routes to #show" do
      get("/game/1").should route_to("game#show",:id => 1)
    end

  end
end

抛出错误：

1) gameController routing routes to #show
     Failure/Error: get("/game/1").should route_to("game#show",:id => 1)
       The recognized options <{"action"=>"show","controller"=>"game","id"=>"1"}> did not match <{"id"=>1,"action"=>"show"}>,difference:.
       <{"id"=>1,"action"=>"show"}> expected but was
       <{"action"=>"show","id"=>"1"}>.
