APP专项性能测试 TestNG ReportNG

1.JAVA环境配置

TestNG是一个Java的框架，所以第一个要求是JDK要安装在你的机器上。

安装JDK1.7以上版本，配置环境变量

2.TestNG环境配置

下载最新版本的TestNG的jar文件，详细请点击访问 http://www.testng.org。

我的版本是testng-6.9.11-20160301.075434-41.jar

把JRA包放在一个文件夹中F:\testng

配置环境变量：

TESTNG_HOME    F:\testng

CLASSPATH   %TESTNG_HOME%\testng-6.9.11-20160301.075434-41.jar

3. 创建一个Java类

打开Eclipse，新建Java Project ，名称：TestNGTest

右键单击 TestNGTest，新建class，名称：TestNGSimpleTest 

4.安装TestNG插件

点击help--Install New Software--点击ADD--收入网址 http://beust.com/eclipse--

选中TestNG后一路点击Next下去安装即可，直到Finished之后，重启Eclipse完成安装。

5.输入代码

import java.io.IOException;
import java.io.InputStreamReader;

添加TestNG用例，如果报错，点击错误点，会自动提示，这是需要添加 TestNG library，排除所有错误后，在代码中右键点击，选择Run As ----TestNG Test，至此TestNG可以应用了。

            @Test
	    public void testadd1() throws IOException, InterruptedException {
	        
	        for(int i =1;i<10;i++){
	        	
	        Reporter.log("第"+i+"次"+"----------------------------------------------------------");
	        Reporter.log("包名 : me.chunyu.ChunyuDoctor");
	        Reporter.log("PID:"+PID("me.chunyu.ChunyuDoctor"));
	        Reporter.log("CPU:" + GetCpu("me.chunyu.ChunyuDoctor"));
	        Reporter.log("Memory:" + GetMemory("me.chunyu.ChunyuDoctor"));
	        Reporter.log("总的下载量:"+GetFlow("me.chunyu.ChunyuDoctor")+"M");
	        Reporter.log("每秒下载量:"+Flow("me.chunyu.ChunyuDoctor")+"M");
	        
	        }
	    }

三.配置reportNG

将4个jar包添加到项目的build path中，其中问了避免中文产生乱码，我直接做好了reportNG-1.1.5.jar替代reportNG-1.1.4.jar，省去了乱码的麻烦

下载包地址： 点击打开链接  http://download.youkuaiyun.com/detail/u011910905/9472603

四.配置TestNG

目的是为了输出reportNG的格式，美观，数据统计

Window--Preferences，按照下面的输入填写内容，大功告成。

输入的内容：

org.testng.internal org.testng.TestRunner org.testng.SuiteRunner org.testng.remote.RemoteTestNG org.testng.TestNG sun.reflect java.lang

org.uncommons.reportng.HTMLReporter

最后，运行代码，要以Run As --TestNG Test的方式运行，最后生出下面的结果
