Rails对任意或自定义URL的功能测试 [英] Rails Functional Test of Arbitrary or Custom URLs

问题描述

我在我的Rails应用程序中有一个RESTful资源称为照片。我使用回形针来为我的照片提供不同的样式（缩略图等） ），我使用自定义路线来REST式访问这些样式：

  map.connectphotos /：id / style / * style，：controller => photos，：action => show
  

这很好，但我想写一个测试， 。

我已经有一个功能测试来调用Photo控制器的show action（事实上由scaffold生成）：

  test应该显示照片do 
 get：show，：id =>照片（：一）.to_param 
 assert_response：success 
 end 
  

在URL/ photo / 1执行动作。现在我想测试URL/ photo / 1 / style / foo的执行。不幸的是，我似乎不能得到ActionController :: TestCase命中该URL; get方法总是想要一个动作/ id，不接受URL后缀。

如何测试自定义URL？

更新

在检查@ fernyb的回答时，我发现这个片段在同一个rdoc

要获取或发布的URL或命名路由。
def send_to_jail
get'/ jail'
assert_response：success
assert_templatejail / front
end

但是，当我实际尝试时，会收到一条错误消息：

  testshould get photodo 
 get/ photos / 1 / style / original
 assert_equal（image / jpeg，@ response.content_type）
 end 
 
 ActionController :: RoutingError：没有路由匹配{：action =>/ photos / 1 / style / original，：controller =>photos} 
 
解决方案

使用 assert_routing 测试路由：
  assert_routing / photos / 10 / style，：controller =>photos，：action =>show，：id =>10，：style => []）
 
 assert_routing（/ photos / 10 / style / cool，：controller =>photos，：action =>show，：id =>10，：style => ]）
 
 assert_routing（/ photos / 10 / style / cool / and / awesome，：controller => photos，：action => show，：id => 10，：style => [cool，and，awesome]）
  
 
 
 < ，您可以执行以下操作：
 测试获取照片do 
 get/ photos / style / cool
 assert_response：success 
 end 
  
 
I have a RESTful resource in my Rails app called "Photo". I'm using Paperclip to serve different "styles" of my photos (for thumbnails and the like), and I'm using a custom route to RESTfully access those styles:
map.connect "photos/:id/style/*style", :controller => "photos", :action => "show"
That's working fine, but I want to write a test to make sure it stays that way. 

I already have a functional test to call the Photo controller's show action (generated by scaffold in fact):
test "should show photo" do
  get :show, :id => photos(:one).to_param
  assert_response :success
end
That tests the execution of the action at the URL "/photo/1". Now I want to test the execution of the URL "/photo/1/style/foo". Unfortunately, I can't seem to get ActionController::TestCase to hit that URL; the get method always wants an action/id and won't accept a URL suffix.

How do I go about testing a custom URL?

Update

While checking on @fernyb's answer I found this snippet in the same rdoc

  
In tests you can simply pass the URL or named route to get or post. 
      def send_to_jail
        get '/jail'
        assert_response :success
        assert_template "jail/front"
      end
However, when I actually try that, I get an error message:
test "should get photo" do
  get "/photos/1/style/original"
  assert_equal( "image/jpeg", @response.content_type )
end  

ActionController::RoutingError: No route matches {:action=>"/photos/1/style/original", :controller=>"photos"}
I wonder if I'm doing something wrong.
解决方案
Use assert_routing to test routes:
assert_routing("/photos/10/style", :controller => "photos", :action => "show", :id => "10", :style => [])

assert_routing("/photos/10/style/cool", :controller => "photos", :action => "show", :id => "10", :style => ["cool"])

assert_routing("/photos/10/style/cool/and/awesome", :controller => "photos", :action => "show", :id => "10", :style => ["cool", "and", "awesome"])
In your integration test you can then do:
test "get photos" do
   get "/photos/10/style/cool"
   assert_response :success
end
