webdriver 3 beta2ウィンドウを閉じることができません

Question

互換性をテストするために、webdriver 3 beta 2に更新したいと考えています。
セレンwebdriverを：3.0.0-beta2の
のFirefox：48.0
OS：Windows 7の
コード：

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.firefox.FirefoxDriver; 
import org.openqa.selenium.remote.DesiredCapabilities; 

public class GeckDriverTest { 

    public static void main(String[] args) { 
     System.setProperty("webdriver.gecko.driver", "src/test/resources/wires.exe"); 
//  System.setProperty("webdriver.firefox.marionette", "src/test/resources/geckodriver.exe"); 
//  System.setProperty("webdriver.gecko.driver", "src/test/resources/geckodriver.exe"); 
     DesiredCapabilities cap = DesiredCapabilities.firefox(); 
     cap.setCapability("marionette", true); 
     cap.setCapability("firefox_binary", "firefoxbinarypath"); 
     WebDriver browser=new FirefoxDriver(cap); 
     browser.get("http://www.seleniumhq.org/"); 
     browser.findElement(By.linkText("Download")).click(); 
     browser.close(); 
    } 
} 

しかし、ブラウザが閉じをしません。
私はbrowser.quit()を使用しますが、エラーがスローされた場合には閉じ：

Answer 1

は新しいDesiredCapabilitiesインスタンスを作成してみてください。代わりに、すでに私たちはキャップや能力としてそれに名前を付けるならば、それは違いはありませんthere..andさ

cap.setCapability("marionette", true); 
cap.setCapability("firefox_binary", "firefoxbinarypath");
