使用rspec测试具有子域约束的​​路由

Question

我无法让我的rspec路由测试使用子域约束。

具体来说，我有一条路线

constraints :subdomain => "api" do
  resources :sign_ups, :only => [:create]
end

和（其中）测试

it "does allow creation of sign ups" do
  {:post => "/sign_ups"}.should route_to(
    :controller => "sign_ups",
    :action => "create",
  )
end

如果我删除了该测试通过的子域约束，但是使用它会失败。我必须告诉rspec使用子域名，但我不知道如何

TIA

我通常会这样做：

let(:url)     { "http://api.domain.com"     }
let(:bad_url) { "http://bad_url.domain.com" }

it "does allow creation of sign ups" do
  {:post => "#{url}/sign_ups"}.should route_to(
   :controller => "sign_ups",
   :action => "create",
  )
end

it "should not route" do
  {:post => "#{bad_url}/sign_ups"}.should_not route_to(
   :controller => "sign_ups",
   :action => "create",
  )
end
