Ручка предупреждает, что нет в селене 3 java

Question

У меня проблема, потому что я хочу обработать предупреждение при выполнении javascript. Все в selenium 3.0.1, JDK 1.8 и Firefox версии 51.0.1.

Мой код:

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); 
     } 
    } 
} 

В выходе я получаю:

Answer 1

Вы должны правильно создать экземпляр драйвера через:

WebDriver driver = new FirefoxDriver(capabilities); 

Похоже, что вы попали эту ошибку: https://github.com/mozilla/geckodriver/issues/431

Answer 2

Да, я забыл о возможностях, но когда я добавляю возможности, я получаю все время на выходе:
