在写selenium的时候，发现很简单的case也报错
package com.lv.test;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Orders {
private WebDriver driver = new ChromeDriver();
String orderUrl="http://www.baidu.com";
@Test
public void OrdersPage(){
driver.get(orderUrl);
System.out.println(driver.getTitle());
driver.quit();
}}

百度后知道这是由于Chrome和chromeDriver的不匹配造成的
然后就查到Chrome和chromeDriver的对应关系如下，以供参考

接在来知道了你目前为止所需求的chromeDriver的版本号之后，就去这里http://chromedriver.storage.googleapis.com/index.html下载，这个链接是发现的目前为止下载最快，可以打开，资源最好的。
然后下载下来的是一个压缩包，解压其中的.exe文件后，放到Chrome的安装目录下
我的安装目录是：C:\Program Files (x86)\Google\Chrome\Application
如果你是直接复制替换文件，可能会提醒文件被占用的什么东西，可能是刚才你跑selenium的时候没有写diriver.quit()
（哎，这坑我都能踩，也是醉了，所以说不管写多简单的case都要最后quit一下，别图省事），只需要打开任务管理器，结束chromedriver.exe就好
