如何匹配水豚的css類和文本

Question

我有以下整合步驟來檢查.credits_count類和0 credits on it。

it "show credits available at the top." do 
    user = Factory.create(:user) 
    login_as(user, :scope => :user) 
    page.should have_selector('.credits_count', text: '0 credits') 
end 

的問題是，我收到以下錯誤時.credits_count是其文本的頁面上。

Credits when user is non-enabled show user credits available at the top. 
    Failure/Error: page.should have_selector('.credits_count', text: '0 credits') 
    expected css ".credits_count" with text "0 credits" to return something 
    # ./spec/requests/credits_spec.rb:12:in `block (3 levels) in <top (required)>' 

任何想法爲什麼它沒有看到.credits_count選擇器？

視圖佈局看起來像這樣。

# app/views/layouts/application.html.haml 
- if current_user 
    %li.credits_count 
    = current_user.credits_count 
    credits

爲了使水豚「頁」工作，你需要檢索與該頁面水豚的「訪問」，看this question about RSpec and Capybara。
