如果有机会参与Skywalking插件开发的同学,除了根据官方文档来本地测试,希望这篇文档也能帮到你。

1、关于 Plugin-test 官方文档解读
环境需求:
- MacOS/Linux
- Jdk8 及以上
- docker环境
2、基础镜像依赖
主要涵盖JDK和Container两块:
- 仅JVM环境,无需tomcat的情况:面向内嵌的Web应用服务器,比如SpringBoot项目,默认
eclipse-temurin:8-jdk
,如果JDK调整可以自行去搜索其他版本,比如eclipse-temurin:17-jdk
- 需要额外Tomcat环境:面向无Web应用服务器的项目,比如Spring项目,默认
tomcat:8.5-jdk8-openjdk
,如果JDK调整可以自行去搜索其他版本,比如tomcat:10.1-jdk17-temurin
3、测试用例项目介绍
- 测试用例项目什么时候写?
有新增插件类型,现有的测试用例通过增加版本已经不满足流程测试需求,此时需要增加额外的一个测试用例项目,便于他们快速熟悉插件的使用逻辑 - 测试用例项目怎么写?
可以参照下面的流程来组织项目 - 测试项目提交前需要满足什么?
按照下面的流程完成本地的自测,跑通后可以提交 - 如果项目跑起来测试能够正常,测试工具无法跑通,怎么办?
可能是测试工具中的一次不适配,可以自己研究测试工具的源码
项目主体架构

startup.sh
仅 JVM 类型有这个脚本,比如:
bash
home="$(cd "$(dirname $0)"; pwd)"
java -jar ${agent_opts} -Dskywalking.plugin.feign.collect_request_body=true \
-Dskywalking.plugin.feign.supported_content_types_prefix='application/json,text/' ${home}/../libs/feign-scenario.jar &
expectedData.yaml
预期数据的情况,做验证
运算符:
- nq: 不等于
- eq: 等于
- ge: 大于等于
- gt: 大于
默认字符串:
- not null: 不为空
- not blank: 不为空,不为空字符串
- null: null或者空字符串
- eq: 等于
- start with: 测试字符串以什么开头
- end with: 测试字符串以什么结尾

4、实际测试
bash
#进入项目根目录
>> cd ~/skywalking
#执行脚本 --debug可以输出真实执行过程中的数据
>> bash ./test/plugin/run.sh -f spring-scenario
#脚本中会根据JDK版本进行基础的编译打包
>> mvn -q --batch-mode -f ~/skywalking-java/test/plugin/pom.xml -DskipTests -Dbase_image_java=eclipse-temurin:17-jdk-ubi9-minimal -Dcontainer_image_version=1.0.0 clean package
