# jacoco代理方式获取测试后端覆盖率

## 步骤
* 首先，from https://www.eclemma.org/jacoco/ 官网下载jacococoagent和jacococli jar最新的0.8.5版本zip包
* 项目打包

       ./gradlew clean build 
* 加上javaagent参数，命令行运行项目
      
       java  '-javaagent:<path-of-jar>/jacocoagent.jar=address=*,includes=*,port=36320,destfile=jacoco-it.exec,output=tcpserver' -jar build/libs/code-coverage-with-jacoco-agent.jar 

* 访问项目不同的接口，获得代码覆盖率

       curl -X GET http://localhost:8080/test?parameter=9
       curl -X GET http://localhost:8080/test?parameter=50
       curl -X GET http://localhost:8080/getEmployee/123
       curl -X GET http://localhost:8080/getEmployee/456

* 运行命令，将javaagent分析收集的覆盖率报告数据存储到jacoco-it.exec文件中,
  生成脚本文件地址：./build/jacoco-it.exec

       java -jar <path-of-jar>/jacococli.jar dump --address localhost --port 36320 --destfile <path-to-application>/build/jacoco-it.exec

* 生成可读的最终代码覆盖率报告文件（格式包括HTML，CSV，XML),报告地址:./build/jacoco-report/index.html
 
       java -jar <path-of-jar>/jacococli.jar report <path-to-application>/build/jacoco-it.exec --classfiles <path-to-application>/build/classes/java/com/example --sourcefiles <path-to-application>/src/main/java/ --html <path-to-application>/build/jacoco-report

* 查看生成报告

## 参考脚本
```shell
//打包
./gradlew clean build 
//启动
java  '-javaagent:/Users/huisheng.jin/jacoco-0.8.7/lib/jacocoagent.jar=address=*,includes=*,port=36320,destfile=jacoco-it.exec,output=tcpserver' -jar build/libs/code-coverage-with-jacoco-agent.jar
//存储测试覆盖率数据
java -jar /Users/huisheng.jin/jacoco-0.8.7/lib/jacococli.jar dump --address localhost --port 36320 --destfile build/jacoco-it.exec
//访问项目
....
//生成测试报告
java -jar /Users/huisheng.jin/jacoco-0.8.7/lib/jacococli.jar report build/jacoco-it.exec --classfiles build/classes/java/main/com/example --sourcefiles src/main/java/ --html build/jacoco-report
