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) {

    // ...

  }
