1. 通过group关键字完成测试方法的分组，使用testng.xml中的<group>字段来指定分组；

class

package foo;

public class Calculate {
//加法
    public int add(int num1,int num2) {
        return num1+num2;
    }
//减法
    public int subtraction(int num1,int num2) {
        return num1-num2;
    }
//猫咪介绍
    public void cat() {
        System.out.println("我是一只猫咪");
    }
//狗介绍
    public void dog() {
        System.out.println("我是一只小狗");
    }
//绿箩介绍
    public void scindapsus() {
        System.out.println("我是一盆绿箩");
    }
//君子兰介绍
    public void clivia() {
        System.out.println("我是一盆君子兰");
    }
    
}

testng.xml

  <test verbose="2" name="Test">
    <groups>
        <run>
            <!-- <include name="非运算"></include> -->
            <include name="动物"></include>
            <include name="运算"></include>
        </run>
    </groups>
   <classes>
<!--       <class name="foo.CalculateTest"/>
        <parameter name="param1" value="1"/>
        <parameter name="param2" value="2"/>
      <class name="foo.AppTest"/> -->
      <class name="foo.CalculateTest3"/>

testclass:

package foo;

import org.testng.annotations.Test;

public class CalculateTest3 {
  @Test(groups= {"运算"})
  public void addTest() {
      System.out.println("加法测试");
  }
  
  @Test(groups= {"运算"})
  public void subtractionTest() {
      System.out.println("减法测试");
  }
  
  @Test(groups= {"动物","非运算"})
  public void catTest() {
      System.out.println("测试猫");
  }
  
  @Test(groups= {"动物","非运算"})
  public void dogTest() {
      System.out.println("测试狗");
  }
  
  @Test(groups= {"植物","非运算"})
  public void scindapsusTest() {
      System.out.println("测试绿箩");
  }
  
  @Test(groups= {"植物","非运算"})
  public void cliviaTest() {
      System.out.println("测试君子兰");
  }
}
