TestNG DataProvider的几种方法写法

前面写过一个无参的数据提供者方法，还有三种有参数据提供者方法。

一、Method表示当前测试的方法

Dataprovidertest.java代码

package com.tzf.testng;

import java.lang.reflect.Method;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class DataProviderTest {

@DataProvider
public Object[][] providerMethod(Method method){
Object[][] result = null;
if(method.getName().equals("testmethod1")){
result = new Object[][]{new Object[]{1}};
}else if(method.getName().equals("testmethod2")){
result = new Object[][]{new Object[]{2}};
}else{
result = new Object[][]{new Object[]{3}};
}
return result;
}

@Test(dataProvider="providerMethod")
public void testmethod1(int param){
System.out.println("method1 received:"+param);
}

@Test(dataProvider="providerMethod")
public void testmethod2(int param){
System.out.println("method2 received:"+param);
}

@Test(dataProvider="providerMethod")
public void testmethod3(int param){
System.out.println("method3 received:"+param);
}
}

注意这里我的Dataprovider的name值没有指定，默认用的是方法名。 Testng.xml代码

<?xml version="1.0" encoding="UTF-8"?>
<suite name="Suite" parallel="false">
<test name="DataProviderTest">
<classes>
<class name="com.tzf.testng.DataProviderTest" />
</classes>
</test>
</suite>

运行结果代码

RemoteTestNG starting
method1 received:1
method2 received:2
method3 received:3
RemoteTestNG finishing: 145 ms

二、ITestContent当前测试的上下文信息

Dataprovidertest2.java代码

package com.tzf.testng;

import java.util.Random;

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

public class DataProviderTest2 {

@DataProvider
public Object[][] providerMethod(ITestContext context){
String[] groups = context.getIncludedGroups();
int size = 2;
for(String group : groups){
if(group.equals("function-test")){
size = 10 ;
break;
}
}
Object[][] result = new Object[size][];
Random r = new Random();
for(int i=0;i<size;i++){
result[i] = new Object[]{new Integer(r.nextInt())};
}
return result;
}

@Test(dataProvider="providerMethod",groups={"function-test","unit-test"})
public void testmethod1(Integer n){
System.out.println("method1 received:"+n);
}

}

Testng.xml代码

<?xml version="1.0" encoding="UTF-8"?>
<suite name="Suite" parallel="false">
<test name="DataProviderTest2">
<groups>
<run>
<include name="function-test"/>
<exclude name="unit-test"/>
</run>
</groups>
<classes>
<class name="com.tzf.testng.DataProviderTest2" group="function-test"/>
</classes>
</test>
</suite>

运行结果代码

method1 received:338477914
