require "rubygems"
require "selenium/client"
require 'spec/expectations'
require 'win32ole'

URL='http://www.google.com.hk/'
HOST = "localhost"
PORT = 4444
BROWSER = "*iexplore"
TIMEOUT_IN_SECOND = 60
@OPENFILE_TITLE = "选择文件"
@OPENFILE_OPEN = "打开(&O)"

@selenium = Selenium::Client::Driver.new \
    :host => HOST,
    :port => PORT,
    :browser => BROWSER,
    :url => URL,
    :timeout_in_second => TIMEOUT_IN_SECOND

@selenium.start_new_browser_session()

@selenium.open('http://192.168.1.225:8080/videos_captial/popups.html')
@selenium.wait_for_page

def openfile(filepath)
    autoit = WIN32OLE.new("autoitx3.control")
    autoit.WinWait(@OPENFILE_TITLE)
   autoit.WinActivate(@OPENFILE_TITLE)
   autoit.ControlFocus(@OPENFILE_TITLE,"","Edit1")
   autoit.ControlSetText(@OPENFILE_TITLE, "","Edit1",filepath)
   autoit.Send('{ENTER}')
end

@selenium.window_maximize
popup = Thread.new{openfile("c:\\2.rb")} #另起一个线程来监控这个弹出框
@selenium.click("up")
at_exit { Thread.kill(popup) }
