Quickly use Jacobo code coverage statistics

brief introduction

Jacoco Is an open source coverage tool .

Jacoco Can be embedded into Ant 、Maven in , And provides EclEmma Eclipse plug-in unit , You can also use JavaAgent Technical monitoring Java Program .

Many third-party tools provide access to Jacoco Integration of , Such as sonar、Jenkins etc. .

Today's sharing environment is ：

k8s+jenkins Built , It involves in node Generated in the container of the node machine jacoco.exec file , Then copy it to the node machine , Then from the node machine jacoco.exec File copy to jenkins In the code base of , Used to generate reports .

Operation steps

**Step1：** Introduce the corresponding jar To the directory of application services , And modify the startup script of the application service that needs to be monitored

The following is in jenkins The corresponding application service deployment script is adjusted

echo ' cd /opt/ wget http://192.168.214.100:7777/jacoco/tools/jacocoagent.jar # Here a siampleHttp  service , Used to get jar  package  wget http://192.168.214.100:7777/jacoco/tools/jacocoant.jar wget -O buildexec.xml http://192.168.214.100:7777/jacoco/buildexec/build.xml wget http://192.168.214.100:7777/jacoco/tools/cron.sh sh cron.sh& # See... Here step2  Script edited in  sed -i "s#exec java#exec java -javaagent:/opt/jacocoagent.jar=includes=*,output=tcpserver,port=8044,address=127.0.0.1 -Xverify:none -javaagent:/opt/skywalking-agent/skywalking-agent.jar #g" /opt/mt/bin/startup.sh && cd /opt/mt/ && dos2unix -k start.sh && cd /opt/mt/bin/ && dos2unix -k startup.sh && sh startup.sh '> ./start.sh

Step2: It is used to generate jacoco.exec
this jacoco.exec The file is one generated by the fetched code execution file exec file , This file is just Step1 A script file required in .

[[email protected] tools]# more cron.sh
while true;do ant dump -buildfile buildexec.xml;sleep 60;done

Step3: stay jenkins Pull the source code , The generated jacoco.exec Copy the file , Then generate the final execution report

Here is one jenkins job

cd ../test-deploy
wget -O buildreport.xml http://192.168.214.100:7777/jacoco/buildreport/build_test_model.xml
wget -nc http://192.168.214.100:7777/jacoco/tools/jacocoant.jar
wget -nc http://192.168.214.100:7777/jacoco/tools/dlexec.sh
sh dlexec.sh testqyd test-model  # Detailed see step4
ant report -buildfile ./buildreport.xml  # Generate executed reports 
open site:http://192.168.214.100:7777/jacoco/report/testqyd/test-model/jacocoReport/   # Open the report 

Step4: from docker In order to get jacoco.exec file , And then on jenkins Extract the source code directory

[[email protected]]# more dlexec.sh 
platformname=$1
projectname=$2
echo " ############################################# #  from node Node machine download jacoco.exec File execution script  # ############################################# "
case $# in
0)
echo ""
;;

1)
ssh [email protected] "kubectl get pods -n $platformname -o wide"
;;

2)
pnip=`ssh 192.168.214.50 "kubectl --kubeconfig=/etc/kubernetes/kubelet.kubeconfig get pods -n $platformname -o wide|grep $projectname|awk '{print \\$7}'|head -1"`
if [ $pnip == '192.168.214.55' ];then
 pnip='[email protected]'
 rqid=`ssh $pnip "docker ps |grep $platformname/$projectname|awk '{print \\$1}'|head -1"`
 ssh $pnip "docker cp $rqid:/opt/jacoco.exec /opt/test/jacoco.exec"
 scp $pnip:/opt/test/jacoco.exec ./
elif [ $pnip == '192.168.214.56' ];then
 pnip='[email protected]'
 rqid=`ssh $pnip "docker ps |grep $platformname/$projectname|awk '{print \\$1}'|head -1"`
 ssh $pnip "docker cp $rqid:/opt/jacoco.exec /opt/test/jacoco.exec"
 scp $pnip:/opt/test/jacoco.exec ./
else
 echo "not found!"
fi

esac
