Watir:手动关闭警报后尝试刷新页面时抛出"意外警报打开"错误

Question

我已经创建了一个Watir::Browserchrome设置为浏览器的实例.

b = Watir::Browser.new :chrome    

如果我手动关闭警报,然后尝试使用刷新页面

b.refresh

抛出以下错误:

Selenium::WebDriver::Error::UnhandledAlertError: unexpected alert open

当我打电话给b.alert.exists?它返回true.

我尝试使用b.alert.initialize重置警报的状态,但它抛出异常.

有没有办法完全重置浏览器对象的状态？

我也面临着这个问题:

但是我把它放在一个begin-rescue块中成功地摆脱了它.

方法如下:

  begin
    # put line of code which triggers alert on page
  rescue Selenium::WebDriver::Error::UnhandledAlertError
    @browser.alert.ok 
  end
