需求背景:测试数据的导入一般在dataprovider中写入对应的测试数据,当参数较多,组合测试或者接口参数测试的测试数据都需要逐一写数据驱动类,数据准备消耗了大量时间。前一篇博客中介绍了对偶测试的小工具,可以通过变量取值情况直接生成excel形式的测试数据,那么本文将介绍将生成的测试数据作为dataprovider导入到测试类中,通过这种方式,可以极大降低重复工作,提高工作效率。
要把大象装冰箱的三步:
ps:是不是很简单~!再给大家对比一下原有excel中的数据:
果然一行一行的导进去了!
1、配置文件pom.xml中加入
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.15</version>
</dependency>
ps:你懂的,读取excel这种一定要来个依赖包的,这个poi就提供API给java程序读取Microsoft Office格式档案读和写的功能。版本的话,大家与时俱进~~~。
2、写个函数调用依赖包里面的方法读取excel中的数据。

import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;
public class MyDataProvider {
@DataProvider(name = "MyDataProvider")
public static Object[][] getTestData() {
String excelPath = "D:\\testcase\\input.xlsx";
String excelSheet = "test1";
int rowIndex = 0;
int colIndex = 0;
Sheet naviSheet = getSheet(excelPath, excelSheet);
int iLastRowIndex = naviSheet.getLastRowNum();
Row row = naviSheet.getRow(0);
int lastColIndex = row.getLastCellNum();
Object excelData[][] = new Object[iLastRowIndex+1][lastColIndex];
for (rowIndex = 0; rowIndex <= iLastRowIndex; rowIndex++) {
for (colIndex = 0; colIndex < lastColIndex; colIndex++) {
Cell cell = getCell(naviSheet, rowIndex, colIndex);
String paramValue = getCellValue(cell);
excelData[rowIndex][colIndex] = paramValue;
}
}
return excelData;
}
/**
* @Title: getSheet
* @Description: Get the sheet from Excel
* @return: Sheet
*/
private static Sheet getSheet(String path, String sheetname){
InputStream fs = null;
Sheet naviSheet = null;
try {
fs = new FileInputStream(path);
Workbook wb = WorkbookFactory.create(fs);
naviSheet = wb.getSheet(sheetname);
}catch(IOException e)
{
e.printStackTrace();
}catch(InvalidFormatException e)
{
e.printStackTrace();
}
finally {
try {
fs.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return naviSheet;
}
/**

* @return: Cell
*/
private static Cell getCell(Sheet sheet, int rowIndex, int columnIndex) {
Row row = sheet.getRow(rowIndex);
if (row == null) {
row = sheet.createRow(rowIndex);
}
Cell cell = row.getCell(columnIndex);
if (cell == null) {
cell = row.createCell((short) columnIndex);
}
return cell;
}
/**

private static String getCellValue(Cell cell) {
String arg = "";
DecimalFormat df = new DecimalFormat("#");
switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
arg = (cell == null ? "" : cell.getStringCellValue());
break;
case Cell.CELL_TYPE_NUMERIC:
Double dvalue = (cell == null ? 0 : cell.getNumericCellValue());
arg = String.valueOf(dvalue);
if(arg.matches("\\d+.[0]*"))
{
int endIndex = arg.indexOf(".");
arg = arg.substring(0, endIndex);
}
if(arg.matches("^((-?\\d+.?\\d*)[Ee]{1}(\\d+))$"))
{
arg = df.format(dvalue);
}
break;
case Cell.CELL_TYPE_BOOLEAN:
Boolean bool = (cell == null ? false : cell.getBooleanCellValue());
arg = bool.toString();
break;
case Cell.CELL_TYPE_FORMULA:
arg = (cell == null ? "" : cell.getCellFormula());
break;
case Cell.CELL_TYPE_ERROR:
arg = (cell == null ? "" : Byte.toString(cell.getErrorCellValue()));
break;
case Cell.CELL_TYPE_BLANK:
arg = "";
break;
}
return arg;
}
}
ps:MyDataProvider把excel中的数据一个一个读出来,作为数据驱动哦,源码奉上,简单快捷,也可自己定制需求,按需读取~~~。
3、测试类中导入测试数据
package com.netease.vcloud.vod.testcase;
import org.testng.annotations.Test;
import com.netease.vcloud.vod.dataprovider.MyDataProvider;
public class MyTester {
@Test(dataProvider = "MyDataProvider", dataProviderClass = MyDataProvider.class)
public void runTest(String id, String name, String input, String expected) {
System.out.println("Got one test data.");
System.out.println("id:["+id+"]");
System.out.println("name:["+name+"]");
System.out.println("input:["+input+"]");
System.out.println("expected:["+expected+"]");
}
}
输出:

机智的盆友会问,对偶测试中有很多无用的数据或者行的标题和头,这怎么处理呢?读取规则自定义呀~写函数定义从生成的测试数据开始读取就可以了,或者心狠手辣的童鞋直接把无用的字段删除,像我一样.....
要结合对偶测试自动生成excel哦,这样才能最大程度上解放劳动力,但需要自己设计的输入数据也完全可以手动敲进去。希望大家用的开心,用的愉快~!
