試圖測試頁面包含<title>My Title</title>有：如何使用Capybara 2.0測試頁面標題？
# spec/features/reports_spec.rb
require 'spec_helper'
feature "Archive Management" do
subject { page }
describe "Index Page" do
before(:all) { 10.times { FactoryGirl.create(:randomreport) } }
after(:all) { Report.delete_all }
describe "when no search terms present" do
before { visit reports_path }
it { should have_selector('title', text: 'My Title') } # <= Fails w/Capybara 2.0
it { should have_selector('title') } # <= passes
it { should have_text('My Title') } # <= passes
it { should have_selector('h2', text: "Welcome") } # <= passes
end
end
end
錯誤消息：
Failure/Error: it { should have_selector('title', text: base_title) }
Capybara::ExpectationNotMet:
expected to find css "title" with text "My Title" but there were no matches. Also found "", which matched the selector but not all filters.
我知道我可以俯瞰非常明顯，但無法弄清楚它是什麼？ <title>標籤不再被認爲是「選擇器」？！？要麼...？！？
編輯器（Debugger信息）：
如果我下拉到如此巧妙的@shioyama建議調試器很明顯的是，page.body包含<title>My Title</title>。包含<h2>Welcome to My Title Project</h2>並通過的相同page.body！
它似乎在其中找到<title> ... </title>標記，但不是My Title。但它確實找到內中My Title頁面後<a href=\"/\" class=\"brand\">My Title</a>和/或<h2>Welcome to The My Title Project</h2>：
(rdb:1) p page

我可以嘗試在調試器還有什麼弄清楚爲什麼have_selector（「標題」，文：......）？是失敗？
那麼，什麼是測試水豚2.0中的標題的正確方法？
如果你嘗試'應該have_xpath（「//標題[包含（ '＃{base_title}'） ]「）'？ –
@shioyama - 這工作，並通過！我仍然有興趣瞭解爲什麼'have_selector'對我來說不是*工作，但是... – Meltemi
嗯......這個xpath正在測試'
