如何處理操作系統生成彈出使用WebDriver

Question

當我輸入錯誤的用戶名和密碼，一個彈出消息和一個確定按鈕是有阻止我的應用程序。但我無法找到該按鈕的ID因爲螢火蟲沒有在這方面的工作。我搜索了更多的博客，我知道它是操作系統生成彈出，它可以由AutoIT處理。請幫助我如何處理彈出框。這裏是我的代碼。

WebDriver無法直接與對話窗口交互，這是因爲對話窗口是操作系統的域而不是網頁。我想你可以在java中使用Robot類來完成你想要做的鍵盤操作，就像在你的情況下按下Enter鍵來關閉操作系統對話框一樣。

import java.awt.AWTException; 
import java.awt.Robot; 
import java.awt.event.KeyEvent; 

public class RobotExp 
{ 

    public static void main(String[] args) 
    { 

    try { 

      Robot robot = new Robot(); 
      robot.keyPress(KeyEvent.VK_ENTER); 
     } 
    catch (AWTException e) { 
      e.printStackTrace(); 
     } 
    } 
}
