add hover event to capybara

Seems capybara has implemented the hover function

check capybara/selenium/node.rb

class Capybara::Selenium::Node < Capybara::Driver::Node

...

  def hover
    driver.browser.action.move_to(native).perform
  end
...

end

But it’s only a selenium implementation. Not all the browsers implement hover function,
Capybara has not apply the method.

check capybara/session.rb

You have two ways to use the hover function:

1. convert element to selenium element and call hover

   element.native.hover

1. Add the snippet below to hook.rb file under the support directory.

   # Example:
   #
   # find("span.assign").hover
   #
   module Capybara
     module Node
       class Element
         def hover
           @session.driver.browser.action.move_to(self.native).perform
         end
       end
     end
   end
