Question

尝试运行简单的测试selenium Web Driver程序，如下所述：

package com.abc;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Mock_Exam {

    /**
     * @param args   
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        WebDriver driver = new FirefoxDriver();
        driver.get("https://www.google.co.in/");

    }

}

作为java应用程序运行后得到以下错误：
