ruby-on-rails – 路由测试失败：NoMethodError：“/ the / rout

我的测试用例是：

it "routes to #active" do
  get ("/parties/active").should route_to("parties#active")
end

我的路线是：

resources :parties do
  get 'active',:on => :collection
end

当我运行测试用例时,我收到以下错误：

NoMethodError: undefined method `values' for "/parties/active":String

完整错误输出：https://gist.github.com/1748264

当我运行rake路线时,我看到：

active_parties GET    /parties/active(.:format)   parties#active
       parties GET    /parties(.:format)          parties#index
               POST   /parties(.:format)          parties#create
     new_party GET    /parties/new(.:format)      parties#new
    edit_party GET    /parties/:id/edit(.:format) parties#edit
         party GET    /parties/:id(.:format)      parties#show
               PUT    /parties/:id(.:format)      parties#update
               DELETE /parties/:id(.:format)      parties#destroy
          root        /                           parties#show

我正在运行的测试几乎与脚手架生成的测试相同：

it "routes to #new" do
  get("/parties/new").should route_to("parties#new")
end

知道发生了什么事吗？
