Rspec测试找不到匹配的路线

Question

运行一些Rspec测试时出现意外错误。他们是

1) PeopleController redirects when loading root should redirect to the splash page Failure/Error: get '/'

ActionController::UrlGenerationError: No route matches {:action=>"/", :controller=>"people"}

...

2) PeopleController redirects when loading /people/show should redirect to the base person path Failure/Error: get '/show' #/show

ActionController::UrlGenerationError: No route matches {:action=>"/show", :controller=>"people"}

我不明白为什么Rspec找不到路线。

从控制器，people_controller.rb：

class PeopleController < ApplicationController 

... 

    def show 
     redirect_to people_path 
    end 

    def index 
     @people = Person.all 
    end 

... 

从Rspec的文件people_controller_spec.rb：

describe PeopleController do 
    describe "redirects" do 
     context "when loading root" do 
      it "should redirect to the temp page" do 
       get '/' 
       last_response.should be_redirect 
       follow_redirect! 
       last_request.url.should include('/temp') 
      end 
     end 

     context "when loading /people/show" do 
      it "should redirect to the base people path" do 
       get '/people/show' 
       last_response.should be_redirect 
       follow_redirect! 
       last_request.url.should include('/people') 
      end 
     end 
    end 
end 

我的路线：

$ rake routes 
     Prefix Verb URI Pattern     Controller#Action 
... 
     person GET /people/:id(.:format)  people#show 
... 
     root GET /       redirect(301, /temp) 

routes.rb：

Rails.application.routes.draw do 
    resources :temp 
    resources :people 

    # map '/' to be a redirect to '/temp' 
    root :to => redirect('/temp') 
end 

我错过了什么从测试中获得路线以匹配？我可以看到根检测不起作用，因为它在技术上不是由人员控制器处理的（我试图将其作为理智测试进行处理，只会让自己变得更加困惑），但/show失败对我来说真的没有意义。

Answer 1

控制器内测试方法get采取动作参数，而不是路径。如果资源是其成员（而不是集合），你还必须指定id参数，所以：

get :show, id: 1 

将呼吁把PeopleController的一个实例#show行动，params散列，其中包括：{ID： '1'}。

这在Guide to Testing Rails Applications中有更详细的描述。
