测试无法直接访问的RSpec控制器操作 [英] Testing an RSpec controller action that can't be accessed directly

问题描述

我有一个控制器，不能以传统的RESTful方式直接访问，而只能通过特定的URL。

通常我用于在我的控制器规范中使用get和post来调用控制器操作。有没有办法通过访问一个特定的URL来练习我的控制器？

编辑：

我的路线：

  Larzworld :: Application.routes.draw do 
 
 match'/ auth /： provider / callback'=> 'authentications＃create'
 
 devise_for：users，：controllers => {：registrations => registrations} 
 
 root：to => 'pages＃home'
 end 
  

这是我的规格：

  require'spec_helper'
 
描述AuthenticationsController do 
 
 before（：each）do 
 request.env [omniauth.auth] = {provider=> twitter，uid=> 12345678} 
 end 
 
 describe'POST create'do 
 
 it应使用umniauth的uid和提供程序找到身份验证do 
 Authentication.should_receive（：find_by_provider_and_uid）
 post'auth / twitter / callback'
 end 
 end 
 
 end 
  

这里是我收到的错误：

  ：
 1）AuthenticationsController POST创建应该使用uid和提供者从omniauth 
找到认证失败/错误：post'auth / twitter / callback'
没有路由匹配{：action => auth / twitter / callback，：controller =>authentications} 
＃./spec/controllers/authentications_controller_spec.rb:13

解决方案

控制器测试使用四个HTTP动词（GET，POST，PUT，DELETE），而不管您的控制器是否为RESTful。因此，如果您有非RESTful路由（Rails3）：

  match'example'=> ; 'story＃example'
  

这两个测试：

$ b b

  require'spec_helper'
 
 describe StoryController do 
 
描述GET'example'do 
 it应该成功do 
 get：example 
 response.should be_success 
 end 
 end 
 
描述POST'example'do 
它应该成功do 
 post：example 
 response.should be_success 
 end 
 end 
 
 end 
  
 
 
  EDIT 
     
 
 
 
我想你正在混淆控制器测试和路由测试。在控制器测试中，您要检查该操作的逻辑是否正确工作。在路由测试中，您可以检查URL是否到达正确的控制器/操作，以及params哈希是否正确生成。
 
 
 
因此，要测试您的控制器操作， ：
  post：create，：provider => twitter`
  
要测试路由，请使用 params_from （对于Rspec 1）或 route_to （对于Rspec 2）：
  describeroutingdo 
 itroutes / auth /：provider / callbackdo 
 {：post => / auth / twitter / callback} .should route_to（
：controller =>authentications，
：action =>create，
：provider =>twitter ）
 end 
 end 
  
 
I've got a controller that can't be accessed directly, in the traditional RESTful way, but rather only through a particular url.

Normally I'm used to using get and post in my controller specs to call controller actions.  Is there a way that I can exercise my controller by visiting a particular url?

EDIT:

Here is my route:
Larzworld::Application.routes.draw do

  match '/auth/:provider/callback' => 'authentications#create'

  devise_for :users, :controllers => {:registrations => "registrations"} 

  root :to => 'pages#home'
end
Here is my spec:
require 'spec_helper'

describe AuthenticationsController do

before(:each) do
  request.env["omniauth.auth"] = {"provider" => "twitter", "uid" => "12345678"} 
end

describe 'POST create' do

  it "should find the Authentication using the uid and provider from omniauth" do
    Authentication.should_receive(:find_by_provider_and_uid)
    post 'auth/twitter/callback'
  end
end

end
and here is the error I receive:
Failures:
  1) AuthenticationsController POST create should find the Authentication using the uid and provider from omniauth
    Failure/Error: post 'auth/twitter/callback'
    No route matches {:action=>"auth/twitter/callback", :controller=>"authentications"}
    # ./spec/controllers/authentications_controller_spec.rb:13

解决方案
Controller tests use the four HTTP verbs (GET, POST, PUT, DELETE), regardless of whether your controller is RESTful. So if you have a non-RESTful route (Rails3):
match 'example' => 'story#example'
the these two tests:
require 'spec_helper'

describe StoryController do

  describe "GET 'example'" do
    it "should be successful" do
      get :example
      response.should be_success
    end
  end

  describe "POST 'example'" do
    it "should be successful" do
      post :example
      response.should be_success
    end
  end

end
will both pass, since the route accepts any verb.

EDIT

I think you're mixing up controller tests and route tests. In the controller test you want to check that the logic for the action works correctly. In the route test you check that the URL goes to the right controller/action, and that the params hash is generated correctly.

So to test your controller action, simply do:
post :create, :provider => "twitter"`
To test the route, use params_from (for Rspec 1) or route_to (for Rspec 2):
describe "routing" do
  it "routes /auth/:provider/callback" do
    { :post => "/auth/twitter/callback" }.should route_to(
      :controller => "authentications",
      :action => "create",
      :provider => "twitter")
  end
end
