缘由

因为开发那边在转 dubbo 服务，测试也需要了解相关知识，所以有了这篇

前提

java8 及环境变量配置（略）

zookeeper

dubbo 源码中默认的是 Multicast 注册，但实际工作中是用 zookeeper 的

官网下载 zookeeper
修改 zookeeper-3.4.12\conf\zoo_sample.cfg 为 zoo.cfg，并更新内容
运行：zookeeper-3.4.12\bin\zkServer.cmd

#配置文件更新内容：
dataDir=E:\\DevE\\zookeeper-3.4.12\\data
dataLogDir=E:\\DevE\\zookeeper-3.4.12\\log

dubbo 示例

在 dubbo 源码目录中有一个 demo 工程，dubbo-demo，使用 idea 打开

在 parent pom 中增加 zookeeper 依赖

<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.4.12</version>
</dependency>
<dependency>
    <groupId>com.101tec</groupId>
    <artifactId>zkclient</artifactId>
    <version>0.10</version>
</dependency>

修改 Provider 以及 Consumer 中的注册信息为：

<dubbo:registry address="zookeeper://127.0.0.1:2181"/>

按顺序打包：

dubbo-demo-api
dubbo-demo-provider
dubbo-demo-consumer

按顺序运行：

dubbo-provider
dubbo-consumer

查看结果日志，单机版 helloworld 已完成

dubbo admin

安装 dubbo admin 主要方便查看管理 dubbo 服务

官网下载 tomcat8
下载 dubbo admin 源码，并打 war 包，dubbo-admin-2.0.0.war
将 war 包扔进 apache-tomcat-8.5.24\webapps
修改 tomcat 的默认端口，比如我的改成了 8123， apache-tomcat-8.5.24\conf\server.xml
启动 tomcat：apache-tomcat-8.5.24\bin\startup.bat
打开浏览器，访问：http://localhost:8123/dubbo-admin-2.0.0
默认用户名密码都是：root，存在配置文件中：dubbo-admin\src\main\webapp\WEB-INF\dubbo.properties 或修改 apache-tomcat-8.5.24\webapps\dubbo-admin-2.0.0\WEB-INF\dubbo.properties

<!--server.xml-->
<Connector port="8123" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

至此环境搭建完成

自动化测试（junit 及 testng 用例设计）

新建一个 maven 工程，pom 如下

<?xml version="1.0" encoding="UTF-8"?>

resources 目录下新增 dubbo.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <dubbo:reference id="demoService" interface="com.alibaba.dubbo.demo.DemoService" url="dubbo://127.0.0.1:20880" timeout="1000"/>

</beans>

junit demo

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/dubbo.xml"})
public class JunitDemo {

    @Autowired
    DemoService demoService;

    @Test
    public void testDemoService(){
        demoService.sayHello("haha my test");
    }

}

testng demo

@ContextConfiguration(locations = {"classpath:/dubbo.xml"})
public class TestngDemo extends AbstractTestNGSpringContextTests {

    @Autowired
    private DemoService demoService;

    @Test
    public void testDemoService(){
        demoService.sayHello("testng my test");
    }

}

性能测试（jmeter 4.0）

更新 pom 依赖（基于上面自动化的 pom 文件）

增加 jmeter 依赖

增加复制所有依赖包和 snapshot 包到目标位置：${project.build.directory}/lib

<jmeter.version>4.0</jmeter.version>

<dependency>
    <groupId>org.apache.jmeter</groupId>
    <artifactId>ApacheJMeter_java</artifactId>
    <version>${jmeter.version}</version>

jmeter case demo

public class JmeterDemo extends AbstractJavaSamplerClient {

    private static final ApplicationContext context = new ClassPathXmlApplicationContext("dubbo.xml");
    private DemoService demoService;

    @Override
    public void setupTest(JavaSamplerContext arg0){
        demoService = (DemoService) context.getBean("demoService");
    }

    @Override
    public SampleResult runTest(JavaSamplerContext javaSamplerContext) {
        SampleResult sr = new SampleResult();
        sr.sampleStart();
        JSONObject result = demoService.sayHello("jmeter test");
        System.out.println("result:" + result.toJSONString());
        sr.setResponseData(result.get("result").toString(), "UTF-8");
        sr.setSuccessful(true);

        return sr;
    }
}

public class JmeterDemoTest {

    public static void  main(String [] args){
        JavaSamplerContext arg0 = new JavaSamplerContext(new Arguments());
        JmeterDemo test = new JmeterDemo();
        test.setupTest(arg0);
        test.runTest(arg0);
    }
}

run case on jmeter

修改 jmeter 配置文件：apache-jmeter-4.0\bin\jmeter.properties，将被测包及其依赖加入到 jmeter 中
启动 jmeter：apache-jmeter-4.0\bin\jmeter.bat
新建一个任务，线程组，java request，balabala

# 更新jmeter配置文件
search_paths=E:/Workspace/dubbo-test/target/lib;

问题

自动化测试和性能测试的用例如何能重复利用？
降级？
权重？
路由规则？
负载均衡？
等等
