「工具」Dubbo可视化测试工具的设计和实现

    背景


    在研发或测试过程中,经常遇到RPC接口的测试,为此我们写了大量的单元测试用例侵入在系统工程中繁琐的创建接口和测试数据占用了大量的时间为了提高测试效率,开发了FreeFly-Remote-API系统,该系统旨在用通过简单的操作方式实现 dev,qa 甚至online的RPC测试,来释放开发和测试人员的双手。

    设计目标


    1、无侵入性
    严格保证系统独立,且拒绝在任何RPC业务服务中有嵌入相关的代码

    2、易用性
    可视化界面简单,配置简单,能够让任何开发和测试人员便捷使用

    3、高效性
    能够快速返回待查询接口相关信息,并利用缓存进行数据临时存储

    设计思路图示


    业务流转图示

    业务步骤和项目技术栈


    整个过程比较简单,具体流程如下描述:

    1、通过输入pom依赖配置获取相关及依赖jar包,并下载到服务本地
    2、通过java反射和类加载对jar包进行接口信息解析
    3、前端按照解析结构输入参数,并从zookeeper拿取服务地址
    4、远程请求获取数据集展示。

    主要技术栈:

    maven依赖:wagon-ssh,aether (具体描述见下方依赖说明)
    java: 反射,类加载
    注册中心:zookeeper
    RPC服务框架:dubbo
    前端结构暂时:jsTree


    项目主要代码描述:

            </dependency>
    

    【Aether用于在自己的应用中集成Mavne的功能,包括依赖计算、包的分发,对本地和远程仓库的访问,它设计时考虑了对各种类型的依赖包管理仓库的抽象,因此也可以进行扩展以支持其他类似的工具】
    以上引述可以理解是对maven仓库功能的一个支持工具,在本系统中我们会用到该工具获取jar包版本,jar包依赖关系 和jar包下载的功能

    dubbo服务请求代码示例:[ 注册中心初始化方法]

            // 引用远程服务
            ReferenceConfig<GenericService> reference = new ReferenceConfig<GenericService>(); // 此实例很重,封装了与注册中心的连接以及与提供者的连接,请自行缓存,否则可能造成内存和连接泄漏
            reference.setApplication(application);
            reference.setRegistry(registry); // 多个注册中心可以用setRegistries()
            reference.setInterface(interfaceName);//"com.qding.member.service.IMemberAddressRpcService"
            reference.setGeneric(true);
            // 和本地bean一样使用xxxService
            GenericService genericService = reference.get(); // 注意:此代理对象内部封装了所有通讯细节,对象较重
    
            return genericService;
        }
    

    dubbo服务请求代码示例: dubbo泛化调用

      public Object dubboInvokeByParam (String zkEnvKey,String interfaceName, String methodName,String[] pojoName, Object[] paramValueArray) {
    
            GenericService genericService =  initDubboRegister(interfaceName,zkEnvKey);
            //  用Map表示POJO参数,如果返回值为POJO也将自动转成Map
            //  如果返回POJO将自动转成Map
            Object result  = genericService.$invoke(methodName, pojoName, paramValueArray);
            return result;
        }
    

    最终效果

    初始界面

    界面提供 jar包下载所需:groupId,artifactId,version配置输入界面

    接口及结构体展示

    指定接口请求响应结构解析

    选择测试环境并输入相应参数值返回测试结果

    测试返回结果集

    测试用例进行保存

    可对指定接口保存多个测试用例

    以上就是该测试工具的实现过程,第一次在这写东西,如有不妥观者海涵!!
