一.下载jacoco, ant工具
jacoco: http://www.eclemma.org/jacoco/;
ant: http://ant.apache.org 并添加到环境变量;
二.不停jvm, dump出覆盖率数据
在部署的tomcat服务中,/bin/catalina.sh中JAVA_OPTS参数值添加:
-javaagent:/data1/jacoco/lib/jacocoagent.jar=includes=*,output=tcpser
ver,port=2014,address=10.210.230.26
其中:/data1/jacoco/lib/jacocoagent.jar为安装jacoco的jacocoagent.jar包绝对路径;output覆盖率数据输出的形式,有file, tcpserer, tcpclient, 默认是file,file是在jvm停掉时才将覆盖率数据dump出来;address和port可以提供client访问,并dump出覆盖率数据文件, 在build.xml会使用。
启动tomcat服务,sh /bin/startup.sh; 假设tomcat服务为10.210.230.26:8074
三.使用自动化测试跑该tomcat服务
四.ant的build.xml
<?xml version="1.0" encoding="UTF-8" ?> <project name="testCodeCoveage" xmlns:jacoco="antlib:org.jacoco.ant" default="report"> <property name="result.dir" location="/data1/weibo8074/webapps/ROOT/WEB-INF/" /> <property name="result.classes.dir" location="${result.dir}/classes" /> <property name="result.report.dir" location="/data1/hugang/jacocoresult/" /> <property name="result.exec.file" location="./remote.exec" /> <!-- Import JaCoCo Ant tasks, taskdef第三方target --> <taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml"> <classpath path="/data1/jacoco/lib/jacocoant.jar" /> </taskdef> <!--tomcat下bin/catalina.sh在JAVA_OPTS参数新加的 -javaagent:/data1/jacoco/lib/jacocoagent.jar=includes=*,output=tcpser ver,port=2014,address=10.210.230.26会在这个端口上提供client访问,并能dump出此时的覆盖率数据文件:destfile--> <target name="dump"> <jacoco:dump address="10.210.230.26" reset="false" destfile="${result.exec.file}" port="2014" append="false"/> </target> <target name="report" depends="dump"> <!-- Create coverage report --> <jacoco:report> <!-- This task needs the collected execution data and ... --> <executiondata> <file file="${result.exec.file}" /> </executiondata> <!-- the class files and optional source files ... --> <structure name="JaCoCo Ant Example"> <group name="WebV4"> <classfiles> <fileset dir="${result.classes.dir}"/> <!-- 可以指定jar包 --> <!-- include name="*.jar" --> </classfiles> </group> </structure> <!-- to produce reports in different formats. --> <html destdir="${result.report.dir}" /> </jacoco:report> </target> </project>
最后在 destdir路径下 /data1/hugang/jacocoresult/
生成html报告五.展示报告
将报告文件,放到apache服务器下,直接访问html,如下:
