Rspec測試失敗慘不忍睹

Question

所以我在這裏看到了幾個與我的有點類似的問題，但還不夠近，無法幫助我弄清楚我的問題是什麼......所以對於我做錯了什麼的幫助將會是讚賞：（我下面的邁克爾·哈特爾對我已經是如何從他的例子偏離是特別有用的教程等等信息）... THX

I'm throwing the following 2 errors:

&最後我的意見/ users/edit.html.erb

<% provide(:title, "Edit user") %> 
<h1>Update your profile</h1> 

<div class="row"> 
    <div class="span6 offset3"> 
    <%= form_for(@user) do |f| %> 
     <%= render 'shared/error_messages' %> 

     <%= f.label :name %> 
     <%= f.text_field :name %> 

     <%= f.label :email %> 
     <%= f.text_field :email %> 

     <%= f.label :password %> 
     <%= f.password_field :password %> 

     <%= f.label :password_confirmation, "Confirm Password" %> 
     <%= f.password_field :password_confirmation %> 

     <%= f.submit "Save changes", class: "btn btn-large btn-primary" %> 
    <% end %> 

    </div> 
</div> 

任何和所有幫助正確的修復將不勝感激。謝謝，

Answer 1

如果您正在關注Rails教程，則需要將您的Capybara版本降級到1.1.2，並將您的規格移至spec/requests目錄中。更新您的Gemfile：

gem 'capybara', '1.1.2' 

如果你打算使用水豚2.0，我建議閱讀本：

http://alindeman.github.io/2012/11/11/rspec-rails-and-capybara-2.0-what-you-need-to-know.html

Answer 2

put, get, post, delete和用於控制器測試的那些方法在功能測試中不可用。

在編寫功能測試時，您應該通過按鈕動作/ ajax/etc ...「提交」put，而不是像控制器測試那樣發佈到控制器。

Answer 3

的問題是：你搞亂請求（capybara）測試與功能測試。

在capybara你應該描述用戶的步驟，因爲這樣的

require 'spec_helper' 

describe "Website access" do 
    context "when I am a registered user" do 
    it "should let me in" do 
     page.fill_in 'Email', with: 'vader@deathstar.com' 
     page.fill_in 'Password', with: 'mydearluke' 
     page.click_link 'Let me in' 

     page.should have_content('Welcome, cheif!') 
    end 
    end 

    context "when I am not a registered user" do 
    it "should not let me in" do 
     page.fill_in 'Email', with: 'jabba.h@tatooine.com' 
     page.fill_in 'Password', with: 'wormsarmageddon' 
     page.click_link 'Let me in' 

     page.should have_content('Incorrect credentials!') 
    end 
    end  
end 

功能測試在較低的水平運行，因爲需要使用HTTP動詞put，get，post，delete與應用程序進行通信你正在測試。

require 'spec_helper' 

describe SessionsController do 
    context "when I am registered user" do 
    it "should let me in" do 
     post :create, email: 'vader@deathstar.com', password: 'mydearluke' 

     response.should be_success 
    end 
    end 

    context "when I am not a registered user" do 
    it "should not let me in" do 
     post :create, email: 'jabba.h@tatooine.com', password: 'wormsarmageddon' 

     response.should_not be_success 
    end 
    end  
end 

幾件事情需要注意：

1. 我使用post，不put。
2. 我在describe區塊中指定控制器名稱，與水豚測試中的純英文desctiption相反。
3. 功能測試規定了如何完全是一個SessionController應該給不同的用戶憑據（它應該創造良好的用戶會話，並尖叫回到一個未註冊的）響應。

你所要做的是在你的要求（豚）測試使用動詞從功能測試。這是錯誤的。

回顧一下：

1. 使用visit和click_link/click_button在capybara測試。
2. 在功能測試中使用HTTP動詞（put,get,post, delete）。
3. 使用devise gem進行用戶認證。
