ruby-on-rails - youtube 视频中的 Phantom JS 错误

Question

幻影 JS 版本:1.9.1
恶作剧版本:1.3.0

从今天开始，YouTube 嵌入的视频现在在运行 javascript 测试时会出现 poltergeist 错误。我的 youtube 代码只是默认的嵌入 youtube 代码。下面是一个例子:

<iframe width="560" height="315" src="//www.youtube.com/embed/AW9Z3cGOlGM?rel=0" frameborder="0" allowfullscreen></iframe>

我在启用 javascript 时访问该页面所得到的错误是:

 Failure/Error: page.find(".container.registrations.false.government")["style"].should have_content("test.jpg")
 Capybara::Poltergeist::JavascriptError:
   One or more errors were raised in the Javascript code on the page. If you don't care about these errors, you can ignore them by setting js_errors: false in your Poltergeist configuration (see documentation for details).

   TypeError: 'null' is not an object (evaluating 'a.dataset')

同样在一些测试中，poltergeist 就死了。

 Failure/Error: visit root_path
 Capybara::Poltergeist::DeadClient:
   PhantomJS client died while processing {"name":"visit","args":["http://subdomain13.lvh.me:3003/"]}

此外，它在执行以下操作时不会忽略这些错误:

Capybara.register_driver :poltergeist_without_js do |app|
  Capybara::Poltergeist::Driver.new(app, :js_errors => false)
end
Capybara.javascript_driver = :poltergeist_without_js

这是不支持 flash 或 html5 视频的嵌入 JS 处理浏览器中的一个错误:
