docker+jacoco构建接口测试覆盖率

发布时间 2023-07-19 23:11:51作者: 土豆炖洋芋

代码中需要更改的内容

Dockerfile

1.在文件中引入jacocoagent.jar，引入后需检查是否引入成功

ADD ./jacocoagent.jar  /jacocoagent.jar

2.打开jacocoagent监控端口，不能与其他jacocoagent端口重复，此端口也是docker容器启动的必填项

EXPOSE 9926

3.加入jacocoagent启动参数，端口号与第2条填入的参数相同，address由于是docker环境所以默认填0.0.0.0

-javaagent:jacocoagent.jar=includes=*,output=tcpserver,port=9926,address=0.0.0.0

pom.xml

引入jacoco

<!--代码覆盖率依赖-->
        <dependency>
            <groupId>org.jacoco</groupId>
            <artifactId>org.jacoco.agent</artifactId>
            <version>0.8.7</version>
            <classifier>runtime</classifier>
        </dependency>

到此代码部分的已经设置完成，接下来是docker的设置

在原有的容器端口外，加上上面设置的jacocoagent端口，设置完成后，点击ok

到此，覆盖率文件已经生成，接下来是获取覆盖率文件exec

首先在服务端机器上配置ant

然后创建build.xml，用于通过ant获取覆盖率文件

<?xml version="1.0" encoding="UTF-8"?>
<project name="Jacoco" xmlns:jacoco="antlib:org.jacoco.ant" default="jacoco">   
    <property name="jacocoantPath" value="D:\jacocoant.jar"/>
    <property name="integrationJacocoexecPath" value="jacoco-integration.exec"/>
    
    <taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml">
      <classpath path="${jacocoantPath}" />
    </taskdef>

	<?如果需要获取多个容器的覆盖率信息，则dump里添加多个的jacocoagent监控端口就可?>
    <target name="dump">
	    <jacoco:dump address="192.168.99.99" port="9926" reset="false" destfile="${integrationJacocoexecPath}" append="true"/>
    </target>
</project>

最后，使用idea分析覆盖率文件即可！
