The Drag & Drop Challenge.... Can you automate this? I can't... Have tried: phantomjs, capybara-webkit, selenium (firefox & chrome)...

challenge_spec.rb

describe 'dragging and dropping', type: :js do

  let(:manually) { page.driver.browser.action }

  specify do

    visit 'http://html5demos.com/drag'
    find('#two').drag_to find('#bin')

    #doesn't work so try...
    Capybara.current_driver = :selenium
    # I've tried both firefox and chrome... 

    visit 'http://html5demos.com/drag'
    manually.click_and_hold find('#two').native
    manually.move_by -200, 0
    manually.release
    manually.perform
    page.should_not have_css '#two'
    #still doesn't work :(
  end
  
end
