package Pack1; 

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

public class L1 { 

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     WebDriver driver= new FirefoxDriver(); 

     driver.get("https://mail.google.com/"); 
    } 
}

硒的當前版本，你需要設置geckodriver exe文件路徑中使用FireFoxDriver

因此獲得下載geckodriver exe文件運行腳本from here

並在您的代碼中設置如下：

System.setProperty("webdriver.gecko.driver","D:\\geckodriver.exe"); 
WebDriver driver= new FirefoxDriver();
