线上第七期_接口测试应用 dubbo 与 swagger_20190112

[seveniruby (思寒)]

Dubbo的介绍

• Apache Dubbo
• https://github.com/apache/incubator-dubbo

搭建dubbo环境

• https://dubbo.incubator.apache.org/zh-cn/docs/admin/install/zookeeper.html
• https://dubbo.incubator.apache.org/zh-cn/docs/admin/install/admin-console.html

搭建注册中心

wget http://archive.apache.org/dist/zookeeper/zookeeper-3.3.3/zookeeper-3.3.3.tar.gz
tar zxvf zookeeper-3.3.3.tar.gz
cd zookeeper-3.3.3
cp conf/zoo_sample.cfg conf/zoo.cfg

zoo.conf的配置，修改一个本地的目录

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
dataDir=/root/dubbo/zookeeper-3.3.3/data
# the port at which the clients will connect
clientPort=12181

熟悉docker的也可以用docker完全搭建起来

客户端测试

echo dump | nc jenkins.testing-studio.com 12181

maven安装

需要3.1版本以上

• Maven – Download Apache Maven

管理控制台搭建

• https://dubbo.incubator.apache.org/zh-cn/docs/admin/install/admin-console.html

修改zookeeper的默认连接端口地址12181

更改默认端口

mvn --projects dubbo-admin-backend spring-boot:run -Dserver.port=18080

切换到老版本的管理控制台

git checkout master
mvn --projects dubbo-admin spring-boot:run -Dserver.port=18080

测试环境地址: http://jenkins.testing-studio.com:18080

provider搭建

• https://github.com/apache/incubator-dubbo-samples

需要修改的地方

• 去掉自带的嵌入式的zookeeper启动代码
• 更改zookeeper的默认地址为12181

git clone https://github.com/apache/incubator-dubbo-samples.git
cd *samples/*basic
#vi src/main/resources/spring/dubbo-demo-provider.xml
mvn clean package
mvn -Djava.net.preferIPv4Stack=true \\
-Dexec.mainClass=org.apache.dubbo.samples.basic.BasicProvider  \\
exec:java

consumer的使用

在独立的另外一个机器上部署

• https://github.com/apache/incubator-dubbo-samples

需要修改的地方

• 更改zookeeper的默认地址为jenkins.testing-studio.com:12181

依赖的接口文件可以通过maven获取

测试用例

import org.apache.dubbo.samples.basic.api.DemoService;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import static org.hamcrest.CoreMatchers.containsString;
import static org.hamcrest.CoreMatchers.equalTo;
import static org.junit.Assert.assertThat;

public class ConsumerTest {
    static ClassPathXmlApplicationContext context;
    static DemoService demoService;
    @BeforeClass
    public static void beforeClass(){
        if(context==null) {
            context = new ClassPathXmlApplicationContext(
                    "consumer.xml");
            System.out.println("load");
            context.start();
            System.out.println("start");
        }
        demoService=(DemoService) context.getBean("demoService");

    }
    @Test
    public void consumer1() throws InterruptedException {

        System.out.println("bean");
        for(int i=0;i<10;i++) {
            System.out.println(demoService.sayHello("思寒 "+i));
        }

    }

    @Test
    public void sayHelloWithNotSafe(){
        String result=demoService.sayHello("");
        assertThat(result, containsString("seveniruby says hello to ,"));
        String result2=demoService.sayHello(" ");
        assertThat(result2, containsString("seveniruby says hello to  ,"));
    }

    @Test
    public void sayHelloWithSpec(){
        String result=demoService.sayHello("\\"");
        assertThat(result, containsString("seveniruby says hello to \\","));
    }

    @Test
    public void sayHelloWithSql(){
        String result=demoService.sayHello("' or 1=1");
        assertThat(result, containsString("seveniruby says hello to \\" or 1=1,"));
    }


}

测试理念 拔高

• 泛化调用打造通用测试框架
• 利用协议代理把http调用转化为dubbo调用，就可以使用RestAssured调用dubbo以及用于其他协议的测试

栽坑

• zookeeper 3.3.3版本无法写入导致无法注册consumer
• dubbo的xml namespace访问出错，mvn clean

作业1

使用consumer连接阿里云上的registry，并调用远程provider，把consumer的输出贴到回复里

作业2

编写基于junit或者testng的consumer测试用例，把测试用例贴到回复里
