如果机器无人参与，则在60秒后ruby browser.send_keys超时。

Question

我和send_keys一起工作，在那里我必须按Enter键

@ie.element(:css, "#accountSwitcherSelect.dijitDownArrowButton").send_keys :enter

这使得切换帐户的另一个对象可见。

@ie.div(:id => "accountSwitcherSelect_dropdown").table(:id => "accountSwitcherSelect_menu")

这就是问题所在，如果我在的话，它就能很好的工作，浏览器就会聚焦在前台。

但是，如果我( a)锁定Windows OS屏幕，或者( b)正在远程桌面上工作，然后切换出RDP，或者( c)从无人值守的机器上的预定任务开始运行ruby脚本，那么它将看到第一个下拉操作非常好

puts @ie.element(:css, "#accountSwitcherSelect.dijitDownArrowButton").visible?

但是它从来不做send_keys :输入，永远不会看到"accountSwitcherSelect_menu“并抛出

60秒后超时

错误

-这是完整的错误消息，其中第125行是

谢谢你@Rajagopalan浏览器窗口焦点问题似乎是现在废弃的watir经典版的一个限制。切换到最新的watir-webdriver解决了这个问题。
