硒铬驱动器不能正确关闭

1. 用绿色结果运行硒测试
2. 手动打开Chrome(或运行一些测试)
3. 获取错误消息“chrome应用程序未正确关闭”

我用这个关闭浏览器和驱动程序:

@AfterClass public static void tearDownClass() {driver.quit();}

我试过:

@AfterClass public static void tearDownClass() {driver.close();}

尝试修复后,我模拟按CTRL+SHIFT+Q:

package SSO_CWP_APPROVAL;

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;

import org.openqa.selenium.WebDriver;


public class Keyboard_events {

    public static WebDriver driver;
    public Keyboard_events(WebDriver driver) {Keyboard_events.driver = driver;}

    public void ctrl_shift_q() throws AWTException, InterruptedException {
        Robot rob = new Robot();
        rob.keyPress(KeyEvent.VK_CONTROL);
        rob.keyPress(KeyEvent.VK_SHIFT);
        rob.keyPress(KeyEvent.VK_Q);
        rob.keyRelease(KeyEvent.VK_CONTROL);
        rob.keyRelease(KeyEvent.VK_SHIFT);
        rob.keyRelease(KeyEvent.VK_Q);
        Thread.sleep(1000);
    }
}

在这种情况下睡觉是必要的。少睡一会儿又犯错误。

@AfterClass public static void tearDownClass() throws AWTException, InterruptedException {K_events.ctrl_shift_q();driver.quit();}

有没有更好的方法关闭浏览器和驱动程序?
