Rails的have_selector不工作的時候選擇是application.html.erb

當我硬編碼在new.html.erb只是我的測試通過了上述的form_tag如下：Rails的have_selector不工作的時候選擇是application.html.erb

<div class="alert alert-error">Invalid email/password combination</div>

但在使用中產生div時application.html.erb中的flash.now消息產生new.html.erb，測試失敗。

--------------- application.html.erb ---------------------

<!DOCTYPE html>

    <a name="top" /> 
    <div id="main_wrapper"> 
    <%= render 'layouts/leaderboard_advertisement' %>

     <section id="main_content_area"> 
      <% flash.each do | key, value | %> 
      <%= content_tag(:div, value, class: "alert alert-#{key}") %> 
      <% end %>   
      <%= yield %>

    it { should have_selector('div.alert.alert-error', text: 'Invalid') } 
    end 
end

根據您的測試，您所做的只是在登錄「登錄」頁面。您並未嘗試登錄，因此沒有顯示錯誤消息。

找到這樣問題的最簡單方法是在測試開始時使用水豚法save_and_open_page。這樣，你可以看到水豚看到它的頁面。這使得測試中的錯誤非常明顯。在這種情況下，您會看到沒有錯誤消息。
