selenium webdriver读取excel进行数据驱动测试

最近做自动化需要从文件读取数据做参数化，网上发现一个不错的解决方案。
准备：新建一个excel文件，文件名为测试类名，sheet名为测试方法名
excel第一行为标题，从第二行开始为测试数据
build path：jxl.jar
code：
  1 import java.io.FileInputStream;
  2 import java.io.InputStream;
  3 import java.util.HashMap;
  4 import java.util.Iterator;
  5 import java.util.Map;
  6 
  7 import org.testng.Assert;
  8 
  9 import jxl.*;
 10 
 11 /**
 12  * Excel放在Data文件夹下</p>
 13  * Excel命名方式：测试类名.xls</p>
 14  * Excel的sheet命名方式：测试方法名</p>
 15  * Excel第一行为Map键值</p>
 16  * 代码参考郑鸿志的Blog

 18  * @ClassName: ExcelDataProvider
