繼邁克爾哈特爾的Rails教程，我測試我的靜態頁面的<title> Minitest在Rails中。Rails：Minitest測試失敗時，他們應該通過
這裏是static_pages_controller_test.rb文件：
require 'test_helper'
class StaticPagesControllerTest < ActionController::TestCase
test "should get home" do
get :home
assert_response :success
assert_select "title", "Home | Microblog"
end
test "should get help" do
get :help
assert_response :success
assert_select "title", "Help | Microblog"
end
test "should get about" do
get :about
assert_response :success
assert_select "title", "About | Microblog"
end
end
這裏是主頁home.html.erb文件：
<!DOCTYPE html>
<html>
<head>
<title>Home | Microblog</title>
</head>
<body>
<h1>Microblog</h1>
<p>
This is the homepage for Microblog, a brand new microblogging app.
</p>
</body>
</html>
help.html.erb和about.html.erb基本上包含相同的內容，有細微的不同。
因此，從我的理解，測試應該通過。
然而，當我運行rake，我得到：

特別是，我不明白爲什麼我得到：
<Home | Microblog> expected but was
<Home | Microblog>..
我缺少什麼？
更新：我去上的教程，跟着在先進的測試設置部分的準則。
這裏是我所得到的，當我運行所有測試與後衛：

我一直在調查問題的原因，但至今沒有發現任何確鑿。
有什麼想法？
真的我不知道，但你有沒有嘗試更換管道字符？或逃脫它？ – rfellons
@fellons這是一個很好的評論，我沒有想過。但是我只是看了一下這些文件，結果發現管道字符不在<%= ... %>標記中。無論如何我用短劃線字符替換它，但得到相同的測試結果。我也逃脫了，但測試仍然沒有通過。真奇怪。這可能是由於我使用的寶石版本。 –
也許在這裏你可以找到如何調試最新情況。 https://coderwall.com/p/bbxb8g/use-ruby-debugger-when-debugging-rspecs – rfellons
