【原创】使用jmeter测试dubbo接口（功能测试）

作者: whooyun发表于: 2017-03-29 16:14

使用jmeter进行dubbo接口测试前需要完成以下工作：

1、搭建好dubbo服务提供方，并进行Junit测试，确保服务提供方能正常运行；

2、搭建好dubbo服务消费方，并且和服务方进行联调，确保服务消费方能正常调用服务提供方；

因为本篇只介绍使用jmeter测试dubbo接口，所以dubbo服务的搭建不在此深究和介绍。

完成以上俩个步骤后继续做以下的操作：

1、在服务消费方中增加Jmeter测试代码；

InitAppContext类 

package com.dubbo;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Created by Administrator on 2017/3/29 0029.
 * 初始化ClassPathXmlApplicationContext
 */
public class InitAppContext {
    private volatile static InitAppContext initApplicationContext;
    private  static ClassPathXmlApplicationContext context;
    private InitAppContext() {
    }

    public static InitAppContext getInstance() {
        if (initApplicationContext == null) {
            synchronized (InitAppContext.class) {
                if (initApplicationContext == null) {
                    initApplicationContext = new InitAppContext();
                }
            }
        }
        return initApplicationContext;
    }
    public void init(){
        try {
            context =new ClassPathXmlApplicationContext(new String[]{"classpath:dubbo-config/dubboConfig.xml"});
            context.start();
        }catch (Exception e){
            e.printStackTrace();
        }
    }

    public ClassPathXmlApplicationContext getApplicationContext(){
        return context;
    }
    public Object getBean(String beanName){
        return context.getBean(beanName);
    }
}

ClassDemoConsumer接口测试类，它继承了AbstractJavaSamplerClient，里面主要setupTest，teardownTest，getDefaultParameters，还有一个上级接口JavaSamplerClient的方法runTest。

setupTest 用来处理运行接口前需要做的操作

runTest 运行你的业务逻辑，也就是调用接口；

teardownTest 运行完以后，需要对接口做的操作，比如销毁context等等；

getDefaultParameters设置自己的请求参数 

package com.dubbo;

import com.alibaba.dubbo.config.spring.ServiceBean;
import com.why.staff.entity.Staff;
import com.why.staff.service.SearchStaffService;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.dubbo.InitAppContext;

import java.util.Random;

/**
 * Created by Administrator on 2017/3/27 0027.
 */
public class ClassDemoConsumer extends AbstractJavaSamplerClient {

    private SearchStaffService demoService = null;

    InitAppContext cntxt = null;

    @Override
    public void setupTest(JavaSamplerContext a) {
        cntxt = InitAppContext.getInstance();
        cntxt.init();
    }

    public SampleResult runTest(JavaSamplerContext arg0) {
        SampleResult sr = new SampleResult();
        try {
            sr.sampleStart();
            System.out.println(cntxt.getBean("searchStaff_lms"));
            SearchStaffService demoService = (SearchStaffService) cntxt.getBean("searchStaff_lms");
            String staffName = demoService.searchOneStaff("admin", "5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8").getStaffName();
            sr.setResponseData("staff is exist,staff's name is " + staffName, null);
            sr.setDataType(SampleResult.TEXT);
            sr.setSuccessful(true);
            sr.sampleEnd();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return sr;
    }

    @Override
    public void teardownTest(JavaSamplerContext context) {
        super.teardownTest(context);
        if(cntxt.getApplicationContext()!=null){
            cntxt.getApplicationContext().destroy();
        }
    }
}

2、把服务消费方测试程序（java控制台程序,original打头）打包成jar，放到jmeter》lib》ext目录下

3、把服务提供方（java控制台程序）打成jar（包括服务消费方依赖的jar）放到jmeter》lib目录下

         注意：记得打包的时候只需要留着消费方依赖的接口和实体类就好了，不然jmeter会当成程序运行（导致无法正常测试），

4、双击jmeter.bat文件（能正常弹出界面，说明jar包没问题），新建jmeter线程组

5、添加java请求，选中自己要测试的接口

把你的测试计划保存下，备查6、新建查看结果树（这样运行的时候就能看到结果了），并点击运行，并双击查看结果树，查看测试结果

另注意：如果你在jmeter的测试代码里面有写System.out.println(),这些信息会在jmeter的控制台输出
