之前的文章有介绍过使用

​​Junit进行参数化测试​​，参数化测试就是一次性执行多个测试用例。本文介绍使用TestNG进行参数化测试。相比Junit，TestNG参数化测试所需要写的代码更加简洁方便。

1 项目结构

2 核心代码

这里主要给出PeopleTestParameterized.java文件，其余文件在上面的文章里有。

package com.example.testng;

import org.testng.Assert;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;

//表示使用参数化测试的方法
//@RunWith(Parameterized.class)
public class PeopleTestParameterized {
  
  private People param;
  private double result;
  
  
  @BeforeTest
  public void setUp() {
    //People people = new People();
  }
  
  @AfterTest
  public void tearDown() {
     
  }
  
  
  @DataProvider(name = "test1")
  public static Object[][] prices(){
    Cap cap = new Cap(1999,0.1,0);
    Jacket jacket = new Jacket(2999,0.2,1);
    Trousers trousers = new Trousers(7999,0.1,1);
    People p_1 = new People(cap,jacket,trousers);
    double re_1 = PeopleTest.cal(cap, jacket, trousers);
    
    
    cap = new Cap(19999,0.1,0);
    jacket = new Jacket(29999,0.2,1);
    trousers = new Trousers(79999,0.1,1);
    People p_2 = new People(cap,jacket,trousers);
    double re_2 = PeopleTest.cal(cap, jacket, trousers);
    
    cap = new Cap(199,0.1,0);
    jacket = new Jacket(9999,0.2,1);
    trousers = new Trousers(799,0.1,1);
    People p_3 = new People(cap,jacket,trousers);
    double re_3 = PeopleTest.cal(cap, jacket, trousers);
    
    cap = new Cap(2199,0.1,0);
    jacket = new Jacket(49999,0.2,1);
    trousers = new Trousers(6799,0.1,1);
    People p_4 = new People(cap,jacket,trousers);
    double re_4 = PeopleTest.cal(cap, jacket, trousers);
    
    cap = new Cap(199,0.1,0);
    jacket = new Jacket(9999,0.2,1);
    trousers = new Trousers(799,0.1,1);
    People p_5 = new People(cap,jacket,trousers);
    double re_5 = PeopleTest.cal(cap, jacket, trousers)+1;
    
    
    
    Object[][] re = new Object[][]{{p_1,re_1},
      {p_2,re_2},
      {p_3,re_3},
      {p_4,re_4},
      {p_5,re_5}};
      
    return re;
    
  }
  
  
  
  @Test(dataProvider = "test1")
  public void testprices(People p, double result) {
    System.out.println(p.getAllprice()+" "+result);
    Assert.assertEquals(p.getAllprice(), result);
  } 
}

JUnit的参数化测试需要@RunWith（Parameterized.class）声明好，创建所有测试用例，为测试用例创建好容器，写好构造函数负责将测试用例依次放入测试用例，最后执行测试代码。
相比JUnit，TestNG要更为简单，创建测试用例，编写测试代码。（其实到这里可以直接执行测试了），如果还要使用xml文件进行测试，那么可以生成一个testng.xml文件进行测试。具体生成方法如下。

点击那个Convert to TestNG

ok了。

再运行就好了。

3 自动生成xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="Suite">
  <test thread-count="5" name="Test">
    <classes>
      <class name="com.example.testng.PeopleTestParameterized"/>
    </classes>
  </test> <!-- Test -->
</suite> <!-- Suite -->

4 执行结果

五个测试用例中故意写错一个，因此是通过四个，错误一个。
