  • 如何使用emma统计代码执行覆盖率...

  • 使用 emma 2.1 (emma-stable-2.1.5320-lib)

    1. 新建 /home/q/java/emmalib 目录, 将emma.jar 与 emma_ant.jar 放入

    2. 复制 /server/bin/mobileserver/runServer.sh 到 runServer_emma.sh

    修改启动语句

    nohup java -Xmx1800M -Xms800m -Xbootclasspath/p:/home/q/java/emmalib/emma.jar -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.EPollSelectorProvider -XX:+AggressiveOpts -XX:+UseParallelGC -server -classpath "$jarFile" com.qunar.common.mobileArc.MobileServer conf/TaLog.property conf/TripServer.property >> $LOG_HOME/error.log 2>&1 &

    复制 /server/bin/mobileserver/stopServer.sh 到 stopServer_emma.sh

    添加覆盖率导出命令

    插入 emma 统计代码

    使用root账号

    1. 备份mobileserver.jar

    cp /server/TripAssistant/mobile-server.jar $MOB_JAR_BAK/mobile-server.jar.{$timestamp}

    2. 执行插入命令

    java -cp /home/q/java/emmalib/emma.jar emma instr -m overwrite -cp mobile-server.jar -out coverage.em

    输出如下:

    EMMA: processing instrumentation path ...

    EMMA: instrumentation path processed in 3117 ms

    EMMA: [1000 class(es) instrumented, 126 resource(s) copied]

    EMMA: metadata merged into [/server/TripAssistant/coverage.em]

    3. 运行mobileserver runServer_emma.sh

    sudo sh /server/bin/mobileserver/stopServer.sh && sudo sh /server/bin/mobileserver/runServer_emma.sh

    在 /server/mobileserverlog/error.log中可见:

    EMMA: collecting runtime coverage data ...

    EMMA: runtime controller started on port [47653]

    emma control 进程已启动

    [root@l-wap4.beta.cn1.qunar.com /server/mobileserverlog]# netstat -na | grep 47653

    tcp 0 0 0.0.0.0:47653 0.0.0.0:* LISTEN 20926/java

    4. 执行 覆盖率文件导出命令

    java -cp /home/q/java/emmalib/emma.jar emma ctl -connect localhost:47653 -command coverage.get,coverage.ec

    可见输出:

    EMMA: processing control command sequence ...

    EMMA: executing [coverage.get (coverage.ec,true,true)] ...

    EMMA: coverage.get: local copy of coverage data merged into [/server/TripAssistant/coverage.ec]

    EMMA: coverage.get: command completed in 79 ms

    EMMA: control command sequence complete

    并且当前目录生成文件 coverage.ec

    5. 生成报告

    java -cp /home/q/java/emmalib/emma.jar emma report -r html -in coverage.em,coverage.ec

    指定源代码生产覆盖率报告(需先上传源码)

    java -cp /home/q/java/emmalib/emma.jar emma report -r html -in /server/TripAssistant/coverage.em,/server/TripAssistant/coverage.ec -Dreport.html.out.file=mycoverage/coverage.html -sp /home/liang.zhou/mob_code_dir/mobs_trunk/src/main/java

    emma 方式启动 mobserver

    ==================================

    1. 判断mobserver.jar size, 大于5M 为已插入过, 小于5M为未插入(需要执行插入)

    2. 执行插入

    3. 启动

    4. 检查启动状态

    47653 端口打开

    mobileserver 进程打开

    emma 方式停止 mobserver

    ==================================

    1. 检查47653端口打开状态, 检查coverage.em是否存在

    2. 导出覆盖率文件 coverage.ec, 备份coverage.em (加上时间戳)

    3. 导出覆盖率HTML report (加上对应时间戳)

    4. kill mobserver 进程

    ls -lt mobile-server.jar

    判断 $? == 0

    判断mobile-server.jar size是否大于 5M


    #!/bin/bash
    function stop_mob_server(){
    #!/bin/bash
    function stop_mob_server(){
    pid=`ps aux | grep MobileServer | grep -v grep | awk '
    Unknown macro: {print $2}
    '`
    ` kill -9 $
    Unknown macro: {pid}
    `
    sleep 1
    echo "Stop mobileserver success."
    }
    #判断 emma ctl 是否启动
    port_check_result=`netstat -na | grep 47653 | awk '
    Unknown macro: {print $1}
    '`
    if [ -z $
    Unknown macro: {port_check_result}
    ]; then
    echo "Emma ctl port 47653 is not LISTEN. Coverage.ec export operation aborted."
    else
    #emma ctl 为启动状态,导出 coverage.ec, 并备份至 /home/q/mobsrv_cov
    if []
    fi
