Rails pages_controller_spec.rb測試不應該失敗，但是，錯誤？

已經由邁克爾·哈特以下的Rails教程Mac OS X上軌3.0版本10.7Rails pages_controller_spec.rb測試不應該失敗，但是，錯誤？

$ rspec的投機/

......FF 

Failures: 

    1) PagesController GET 'help' should be successful 
    Failure/Error: get 'help' 
    ActionController::RoutingError: 
     No route matches {:controller=>"pages", :action=>"help"} 
    # ./spec/controllers/pages_controller_spec.rb:45:in `block (3 levels) in <top (required)>' 

    2) PagesController GET 'help' should have the right title 
    Failure/Error: get 'help' 
    ActionController::RoutingError: 
     No route matches {:controller=>"pages", :action=>"help"} 
    # ./spec/controllers/pages_controller_spec.rb:49:in `block (3 levels) in <top (required)>'

Failed examples: 

rspec ./spec/controllers/pages_controller_spec.rb:44 # PagesController GET 'help' should be successful 
rspec ./spec/controllers/pages_controller_spec.rb:48 # PagesController GET 'help' should have the right title

測試看起來是這樣的：

require 'spec_helper' 

describe PagesController do 
    render_views 

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

    it "should have the right title" do 
     get 'home' 
     response.should have_selector("title", 
     :content => "Ruby on Rails Tutorial Sample App | Home") 
    end 
    end 

    describe "GET 'contact'" do 
    it "should be successful" do 
     get 'contact' 
     response.should be_success 
    end 
    it "should have the right title" do 
     get 'contact' 
     response.should have_selector("title", 
     :content => "Ruby on Rails Tutorial Sample App | Contact") 
    end 
    end 

    describe "GET 'about'" do 
    it "should be successful" do 
     get 'about' 
     response.should be_success 
    end 
    it "should have the right title" do 
     get 'about' 
     response.should have_selector("title", 
     :content => "Ruby on Rails Tutorial Sample App | About") 
    end 
    end 

    describe "GET 'help'" do 
    it "should be successful" do 
     get 'help' 
     response.should be_success 
    end 
    it "should have the right title" do 
     get 'help' 
     response.should have_selector("title", 
     :content => "Ruby on Rails Tutorial Sample App | Help") 
    end 
    end 
end

而且我有in pages_controller.rb

class PagesController < ApplicationController 
    def home 
    @title = "Home" 
    end 

    def contact 
    @title = "Contact" 
    end 

    def about 
    @title = "About" 
    end 

    def help 
    @title = "Help" 
    end 

end

而在routes.rb中我有

SampleApp::Application.routes.draw do 
    get "pages/home" 
    get "pages/contact" 
    get "pages/about" 
    get "pages/help" 
end

當然，我也創造了在應用程序/視圖/ 奇怪的是，當我運行軌道服務器並轉到本地主機頁面help.html.erb頁：3000/pages/help我用合適的標題獲得適當的頁面，使其看起來好像測試應該已經通過，但事實並非如此。此外，聯繫人，家庭和關於測試通過，但當我剛剛添加的幫助它不是因爲某些未知的原因。這真的讓我感到困擾，我忽略了這個簡單的解決方案，它讓我瘋了嗎？

出於某種原因，我help.html.erb文件是275個字節，而我的約，接觸和家庭.html.erb頁面都是2KB，儘管他們幾乎是準確的每個字符的數量相同。這肯定與help.html.erb在測試時不起作用有關。此外，幫助的文檔類型是TextMate文檔，而其他文檔只是說「文檔」。奇怪..？ – Laser 2012-01-18 20:38:05

我認爲你在正確的軌道上 - 代碼中沒有任何東西看起來會失敗。我會嘗試刪除並重新創建help.html.erb文件。 – 2012-01-18 20:39:50

感謝您的想法，不幸的是它沒有幫助。特別奇怪的是，它給我一個錯誤，耙路線是矛盾的，因爲在這裏解釋：http://stackoverflow.com/questions/8917201/my-computer-hates-me – Laser 2012-01-18 20:55:36

下載代碼並運行：

它運行的是得到「幫助」，所以我覺得你在自動測試運行這一點，它不重裝。可能？

謝謝你，退出終端，並打開和新窗口，一切運行良好。簡單是不可思議的。 – Laser 2012-01-18 21:19:53

你的代碼沒問題。問題在於你之前的代碼被緩存了。通過退出終端並打開新窗口，您可以清除緩存。如果您在測試環境中不關閉緩存，則可能遇到相同的問題。轉到config/environments/test.rb，改變config.cache_classes = true到config.cache_classes = false
