我有一个无法直接访问的控制器,采用传统的RESTful方式,而只是通过特定的URL.
通常我习惯在我的控制器规范中使用get和post来调用控制器动作.有没有办法通过访问特定网址来运用我的控制器？

这是我的路线：
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'
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
这是我收到的错误：
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
Finished in 0.04878 seconds
1 example,1 failure
解决方法
无论您的控制器是否为RESTful,控制器测试都使用四个HTTP谓词(GET,POST,PUT,DELETE).所以如果你有一个非RESTful路由(Rails3)：
match 'example' => 'story#example'
这两个测试：
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
将通过,因为路线接受任何动词.

我认为你正在混淆控制器测试和路由测试.在控制器测试中,您要检查操作的逻辑是否正常工作.在路由测试中,您检查URL是否转到正确的控制器/操作,并且正确生成了params哈希.
因此,要测试您的控制器操作,只需执行：
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)：
describe "routing" do
it "routes /auth/:provider/callback" do
{ :post => "/auth/twitter/callback" }.should route_to(
:controller => "authentications",:action => "create",:provider => "twitter")
end
end
