我如何解決rspec錯誤ROR教程結束CH 9

Question

我到了Michael Hartl的Ruby on Rails教程第9章的末尾，並且rspec測試失敗。我已經多次閱讀了這一章，並且找不到我做錯了什麼。請幫忙！另外，我是一個兩週的程序員，所以如果你能詳細說明你通過調試的步驟，那將會對我有很大幫助！

我的混帳回購協議是在https://github.com/kerrieyee/sample_app和RSpec的結果如下：

我最終解決前4先取出部分我被渲染到new.html.erb測試失敗和edit.html.erb。因爲我不是一個有經驗的程序員，所以我不確定如何修復本教程中的代碼，並希望任何能告訴我哪裏出錯的人。這是重構的代碼：

<% provide(:title, 'Sign up') %> 
<h1>Sign up</h1> 

<div class="row"> 
    <div class="span6 offset3"> 
    <%= form_for(@user) do |f| %> 
     <%= render 'fields', f: f %> 
     <%= f.submit "Create my account", class: "btn btn-large btn-primary" %> 
    <% end %> 
    </div> 
</div> 

這是部分：

<%= 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 %> 

最後兩個錯誤，我通過在GitHub上看着Michael Hartl's index.html.erb file解決。本質上，問題是index.html.erb代碼需要調用partial _users.html.erb。

請注意password_confirmation標籤文字確認密碼，則需要UDPATE規範象下面這樣： 變化 FILL_IN 「確認書」，以 「foobar的 到 FILL_IN 」確認密碼「，用」 foobar的 我也遇到過這個問題，並以上述方式解決。

Answer 3

確保password_confirmation標籤中的文本與user_pages_spec.rb和new.html.erb中的文本匹配。例如，你想分在new.html.erb看起來像這樣：

<%= 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 "Create my account", class: "btn btn-large btn-primary" %> 
    <% end %> 

和user_pages_spec.rb這樣的：

describe "with valid information" do 
     before do 
      fill_in "Name",    with: "Example User" 
      fill_in "Email",   with: "user@example.com" 
      fill_in "Password",   with: "foobar" 
      fill_in "Confirm Password", with: "foobar" 
     end 
     it "should create a user" do 
      expect { click_button submit}.to change(User, :count).by(1) 
     end 
    end 

Answer 4

亞歷克斯·西蒙娜是正確的我有同樣的問題他解決了它。非常感謝。水豚做我們稱之爲瀏覽器測試。這意味着它有點像去這裏點擊。

作爲我遇到的問題的一個例子，以及我如何解決它。

錯誤

Capybara::ElementNotFound 

意味着它正在尋找按鈕，點擊它無法找到它。如果你看代碼

fill_in "Confirmation", with: "foobar" 

然後你看看網頁，它說確認密碼。你可以讓你的測試通過鍵入

fill_in "Confirm Password", with: "foobar" 

傳給你基本上只需要在你的水豚測試琴絃用什麼，當你看着它，它說在網頁上匹配。
