句柄警告它不在硒3 java

Question

我有一個問題，因爲我想處理警報時，我執行JavaScript。全部在硒3.0.1，JDK 1.8和Firefox版本51.0.1。

我的代碼：

public class SeleniumDemo { 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) { 
     // TODO code application logic here 

     System.setProperty("webdriver.gecko.driver", "C:\\Users\\Damian6666\\Downloads\\geckodriver\\geckodriver.exe"); 
     DesiredCapabilities capabilities = DesiredCapabilities.firefox(); 
     capabilities.setCapability("marionette", true); 

     WebDriver driver = new FirefoxDriver(); 
     driver.get("http://wikipedia.org"); 
     JavascriptExecutor jsx = (JavascriptExecutor) driver; 
     jsx.executeScript("alert('Test Alerts');");  

     try { 
      Thread.sleep(3000); 
      Alert alert = driver.switchTo().alert(); 
      alert.accept(); 
     } catch (Exception e) { 
      System.out.println(e); 
     } 
    } 
} 

在輸出我得到：

Answer 1

你應該正確地通過實例化驅動程序：

WebDriver driver = new FirefoxDriver(capabilities); 

它看起來像你打這個錯誤：https://github.com/mozilla/geckodriver/issues/431

Answer 2

是的我忘記了功能，但是當我添加功能時，我可以全部輸出：
