是否可以通过Selenium Webdriver与Ruby一起使用HTML5拖放来解决问题？我在Ruby 1.9.2中使用Selenium-
Webdriver 2.20.0

这是重现此问题的简单测试：

require "selenium-webdriver"
require "test/unit"

class Html5DragAndDropTest < Test::Unit::TestCase

  def setup
    @driver = Selenium::WebDriver.for :firefox
    @driver.manage.timeouts.implicit_wait = 30
  end

  def teardown
    @driver.quit
  end

  def test_html5_drag_and_drop
    @driver.get("http://html5demos.com/drag")
    target = @driver.find_element(:id, "one")
    source = @driver.find_element(:id, "bin")
    @driver.action.drag_and_drop(target, source).perform
    assert target.displayed? == false
  end
end
