java - 我试图关闭 Webdriver 上的浏览​​器实例，但无法这样做

Question

package erewards2;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class login_sib2 {

    public static void main(String[] args) {

        FirefoxDriver d1 = new FirefoxDriver();

                 d1.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
                 d1.get("https://sib3.erewardsredeem.com/fm/customer.html?action=userLogin");
                 d1.manage().window().maximize();
                 WebElement e4 = d1.findElementByLinkText("Login");
                 e4.click();
                 d1.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
                 WebElement e1 = d1.findElement(By.id("showmemberid"));
                 e1.sendKeys("2800000091");
                 WebElement e2 = d1.findElementById("showmemberpwd");
                 e2.sendKeys("Miquser1");
                 WebElement e3 =  d1.findElementByClassName("loginbtn");
                 e3.click();

                WebElement e5 = d1.findElementByLinkText("Logout");

                 e5.click();



                Alert a1 = d1.switchTo().alert(); //web based alert
                WebDriverWait wait = new WebDriverWait(d1,10);
                wait.until(ExpectedConditions.alertIsPresent()).accept();
                a1.accept();

             System.out.println("test1");

                //close Firefox
                d1.close();
                System.out.println("test2");   
                // exit the program explicitly
                System.exit(0);
                System.out.println("test3");
    }

}

我添加了 system.out println 行用于测试目的，发现我的代码无法从 Test1 语句完全执行。下面是我在 Eclipse IDE 上遇到的异常。

看起来在到达关闭语句之前就失败了。

尝试像这样构建代码:

FirefoxDriver d1 = new FirefoxDriver();
try {
    // steps
}
finally {
    d1.close();
}

这将保证执行 close 语句。
