IEDriverServer可執行仍然硒失敗

Question

後使用Selenium版本2.44和IE版本11.0.9600.17728

如果驅動程序構造失敗，因爲保護模式的設置，EXE保持運行。

似乎退出調用會清理所有工作時的事情，但由於驅動程序從未構建過，因此無法使用。

當構造函數拋出異常時，可以停止EXE嗎？

import org.openqa.selenium.ie.InternetExplorerDriver; 

public class SeleniumTest 
{ 
    public static void main(String[] args) 
    { 
     System.setProperty("webdriver.ie.driver", "C:\\IEDriverServer_Win32_2.44.0.exe"); 

     try 
     { 
      InternetExplorerDriver driver = new InternetExplorerDriver(); 
      driver.get("http://www.google.com"); 
      Thread.sleep(10 * 1000); 
      driver.quit(); 
     } 
     catch (Exception e) 
     { 
      /* 
      * To cause this, change the following IE settings: 
      * 
      * On tab: Internet Options->Security 
      * 
      * Make sure the four zones do not have the same value for "Enabled Protected Mode" 
      */ 
      System.err.println("Failed making the driver"); 
      e.printStackTrace(); 
     } 
     System.exit(0); 
    } 
} 

我看到，當我運行上面的代碼的輸出：

Answer 1

您可以將下面的一段代碼放在catch塊中。

try { 
    Runtime.getRuntime().exec("taskkill /F /IM IEDriverServer.exe"); 
} catch (IOException e) { 
    e.printStackTrace(); 
} 

Answer 2

驅動程序被實例化，甚至測試捕捉異常。當您嘗試導航到URL時，會發生異常，同時驅動程序已經實例化。所以在catch塊中調用quit並且會完成你想要的工作。

import org.openqa.selenium.ie.InternetExplorerDriver; 

public class SeleniumTest 
{ 
    public static void main(String[] args) 
    { 
     System.setProperty("webdriver.ie.driver", "C:\\IEDriverServer_Win32_2.44.0.exe"); 

     try 
     { 
      InternetExplorerDriver driver = new InternetExplorerDriver(); 
      driver.get("http://www.google.com"); 
      Thread.sleep(10 * 1000); 
      driver.quit(); 
     } 
     catch (Exception e) 
     { 
      /* 
      * To cause this, change the following IE settings: 
      * 
      * On tab: Internet Options->Security 
      * 
      * Make sure the four zones do not have the same value for "Enabled Protected Mode" 
      */ 
      driver.quit(); 
      System.err.println("Failed making the driver"); 
      e.printStackTrace(); 
     } 
     System.exit(0); 
    } 
}
