selenium自动化测试中，采用jxl实现参数化（从Excel中读取数据）

声明：本文在http://www.cnblogs.com/liu-ke/p/4223807.html文章基础上稍作修改，并增加了简单的测试调用代码

import java.io.FileInputStream;
import java.io.InputStream;
import java.util.List;
import java.util.ArrayList; 
import org.testng.Assert;
import jxl.*;
 
 /**
  * Excel放在Data文件夹下

  * Excel命名方式：测试类名.xls

  * Excel的sheet命名方式：测试方法名

  * Excel第一行为Map键值

  * 代码参考郑鸿志的Blog
  * {@link www.zhenghongzhi.cn/post/42.html}
  * @ClassName: ExcelDataProvider
  * @Description: TODO(读取Excel数据)
  */

 public class ExcelDataProvider{
 
     private Workbook book         = null;
     private Sheet    sheet        = null;
     private int      rowNum       = 0;
     private int      currentRowNo = 0;
     private int      columnNum    = 0;
     private String[] columnnName;
     
     //重构构造函数，将待测试类名和方法名传入函数
     public ExcelDataProvider(String classname, String methodname) {
 
         try {
 
             int dotNum = classname.indexOf(".");
 
             if (dotNum > 0) {
                 classname = classname.substring(classname.lastIndexOf(".") + 1,
                         classname.length());
             }
             //从/data文件夹下读取以类名命名的excel文件
             String path = "data/" + classname + ".xls";
             InputStream inputStream = new FileInputStream(path);
 
             book = Workbook.getWorkbook(inputStream);
             //取sheet
             sheet = book.getSheet(methodname);
             rowNum = sheet.getRows();
             Cell[] cell = sheet.getRow(0);
             columnNum = cell.length;
             columnnName = new String[cell.length];
 
             for (int i = 0; i < cell.length; i++) {
                 columnnName[i] = cell[i].getContents().toString();
             }
             this.currentRowNo++;
 
         } catch (Exception e) {
             e.printStackTrace();
             Assert.fail("unable to read Excel data");
         }
     }
 
    //判断Excel表中是否存在下一行数据
	public boolean hasNext() {
 
         if (this.rowNum == 0 || this.currentRowNo >= this.rowNum) {
             try {
                 book.close();
             } catch (Exception e) {
                 e.printStackTrace();
             }
             return false;
         } else {
             // sheet下一行内容为空判定结束
             if ((sheet.getRow(currentRowNo))[0].getContents().equals(""))
                 return false;
             return true;
         }
     }
	 //读取Excel中某一行数据，并为下一行做准备
     public List getdata_list() {
    	 
         Cell[] c = sheet.getRow(this.currentRowNo);
         List list = new ArrayList();
 
         for (int i = 0; i < this.columnNum; i++) {
             String temp = "";
             try {
                 temp = c[i].getContents().toString();
             } catch (ArrayIndexOutOfBoundsException ex) {
                 temp = "";
             }
             if(temp != null&& !temp.equals(""))
             list.add(temp);
         }
         
         this.currentRowNo++;
         return list;
     }
     
    public void remove() {
         throw new UnsupportedOperationException("remove unsupported.");     
     }
 }

以下是简单的测试调用代码：

import java.util.List;

import Test.ExcelDataProvider;

public class TestClass {

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

		String class_name = "Login";
		String method_name = "jd_login";
		ExcelDataProvider excel_driver = new ExcelDataProvider(class_name, method_name);
		
		String ErrorUser = "";
		String ErrorPwd = "";
		String RightUser = "";
		String RightPwd = "";
		String RUser = "";
			while(excel_driver.hasNext() == true)
			{
				List info_list = excel_driver.next(); 
				int info_size = info_list.size();
			
				for(int i=0; i

读取的Excel文件中有5列，共4行数据，通过以上方法成功实现了selenium的数据参数化，并成功运用到实际测试脚本中

刚开始接触java，调用程序写的比较笨拙，望见谅，欢迎多提改进意见
