java - webdriver 3 beta2 无法关闭窗口

Question

我希望更新到 selenium webdriver 3 beta 2 以测试兼容性。
Selenium WebDriver:3.0.0-beta2
火狐浏览器:48.0
操作系统:Windows 7
代码:

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();
    }
}

但浏览器没有关闭。
如果我使用 browser.quit() 它会关闭，但会抛出错误:

Answer 1

尝试创建一个新的DesiredCapability实例。

 DesiredCapabilities capabilities = DesiredCapabilities.firefox();

而不是

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