TestNG参数化测试

参数化有两种方法：

第一种：在xml文件中声明

第二种：用@DataProvider注解

先介绍第一种方法：

ParameterTest类：用@Parameters({"name","age"}) 注解声明参数

package com.janson.parameter;

import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class ParameterTest {
    @Test
    @Parameters({"name","age"})
    public void paramTest(String name,int age) {
        System.out.println("name:"+ name);
        System.out.println("age:"+age);
    }
}

在resources文件夹下新建parameter.xml文件：

注：<parameter>标签中的name需要与上面类中的@Parameters({"name","age"}) 一致

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="parameter">
    <test name="parameterTest">
        <parameter name="name" value="janson"/>
        <parameter name="age" value="22"/>
        <classes>
            <class name="com.ucar.parameter.ParameterTest"/>
        </classes>
    </test>
</suite>

执行结果如下：

name:janson
age:22

第二种方法：

package com.janson.parameter;

import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

import java.lang.reflect.Method;

public class DataProviderTest {

    //演示两个参数
    @Test(dataProvider = "twoParam")
    public void dataProviderTest(String name,int age) {
        System.out.println("name = "+name+";age = "+age);
    }

    @DataProvider(name = "twoParam")
    public Object[] provideData() {
        Object[][] o = new Object[][] {
                {"zhangsan",10},
                {"lisi",11},
                {"wangwu",12},
                {"zhaoliu",13}
        };
        return o;
    }

    //演示一个参数
    @Test(dataProvider = "OneParam")
    public void onlyOneDataProvider(int money) {
        System.out.println("my Money is:"+ money+"万");
    }

    @DataProvider(name="OneParam")
    public Object[] oneProvideData() {
        Object[] o = new Object[]{
                100,200,1000,2000
        };
        return o;
    }

    //演示多个参数
    @Test(dataProvider = "manyParam")
    public void manyDataProvider(String name,int age,String nation,int height) {
        System.out.println("name:"+name+",age:"+age+",nation:"+nation+",height:"+height);
    }

    @DataProvider(name = "manyParam")
    public Object[][] manyProvideData() {
        Object[][] o = new Object[][] {
                {"A",20,"中国",180},
                {"B",21,"USA",150},
                {"C",22,"AUS",160},
                {"D",23,"CAN",170}
        };
        return o;
    }

    //演示根据不同方法传不同的参数
    @Test(dataProvider = "methodData")
    public void test1(String name,int age) {
        System.out.println("test1方法: name="+name+",age="+age);
    }

    @Test(dataProvider = "methodData")
    public void test2(String name,int age) {
        System.out.println("test2方法: name="+name+",age="+age);
    }

    @DataProvider(name = "methodData")
    public Object[][] provideMethodData(Method method) {
        Object[][] result = null;
        if(method.getName().equals("test1")) {
            result = new Object[][] {
                    {"ZhangSan",30},
                    {"LiSi",31}
            };
        }else if(method.getName().equals("test2")) {
            result = new Object[][] {
                    {"WangWu",40},
                    {"ZhaoLiu",41}
            };
        }
        return result;
    }
}

执行结果如下：

---两个参数---
name = zhangsan;age = 10
name = lisi;age = 11
name = wangwu;age = 12
name = zhaoliu;age = 13

---多个参数---
name:A,age:20,nation:中国,height:180
name:B,age:21,nation:USA,height:150
name:C,age:22,nation:AUS,height:160
name:D,age:23,nation:CAN,height:170

---一个参数---
my Money is:100万
my Money is:200万
my Money is:1000万
my Money is:2000万

---根据不同方法传入不同参数---
test1方法: name=ZhangSan,age=30
test1方法: name=LiSi,age=31
test2方法: name=WangWu,age=40
test2方法: name=ZhaoLiu,age=41

补充：如果被引用数据源在另一个测试类中定义的，还需要指明其所在测试类，示例如下：

 @Test(dataProvider = "create", dataProviderClass = StaticProvider.class)

  public void test(Integer n) {

    // ...

  }
