The path to the driver executable must be set by the webdriver.gecko.driver system property;

今天安装了webdriver后，编写了一个测试小程序，但运行时控制台报了这样的错误：

 1 Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases

 

解决过程：

1、查了一下，据说报这个错是因为在selenium3中，使用Firefox需要添加驱动。于是从晚上找驱动下载地址：

下载网址1：http://download.csdn.net/detail/just_h_mao/9670229

下载网址2： https://github.com/mozilla/geckodriver/releases/tag/v0.9.0

2、

 

注意：如果firefox安装时使用了非默认安装路径，则可以无法找到firefox.exe来启动执行此脚本的firefox浏览器。在new FirefoxDriver()前设置一下浏览器安装路径即可解决，如下：

 1 package helloworld;
 2 import org.openqa.selenium.*;
 3 import org.openqa.selenium.By.ById;
 4 import org.openqa.selenium.firefox.FirefoxDriver;
 5 
 6 public class JavaTest {
 7 
 8     public static void main(String[] args) {
 9         // TODO Auto-generated method stub
10         
11         WebDriver driver;
12         String baseurl;
13         System.setProperty("webdriver.gecko.driver", "F:\\WebDriver\\下载\\geckodriver-v0.11.1-win64\\geckodriver.exe");
14         driver=new FirefoxDriver();
15         baseurl="http://www.sogou.com/";
16         //打开搜狗首页
17         driver.get(baseurl+"/");
18         //在搜索框输入XX
19         driver.findElement(By.id("query")).sendKeys("XX");
20         //单击搜索按钮
21         driver.findElement(By.id("stb")).click();
22         
23         
24     }
25 
26 }

但运行后还是出现错误：
