<h1>Android自动化性能收集</h1> <p>Android 功能测试自动化框架较多，UIAutomator，Robotium，Appium等。Case执行过程中，可能希望收集手机的性能指标，包括内存、cpu、流量等。使用java+shell+bat简单实现了android手机性能收集。</p> <h2>简述</h2> <p>过程很简单：</p> <ul> <li><p>在启动自动化case前，执行收集信息的命令。<br/> 其实就是一些adb shell命令，如下：</p> <pre><code> adb shell top -n 1| awk '{print $3" "$10}' >> cpu.dat adb shell ps | awk '{print $5" "$9}' >> mem.dat //android sdk level 大于16 adb shell cat /proc/uid\_stat/$uid/tcp\_rcv >> $uid"\_recv.dat" adb shell cat /proc/uid\_stat/$uid/tcp\_snd >> $uid"\_snd.dat" //android sdk level 小于16 adb shell cat /proc/$pid/net/dev | grep wlan | awk '{print $2" "$10}' >> $pid"\_net.dat" </code></pre></li> <li><p>执行自动化case，可能需要很久。这个过程中，上面的命令在不断地执行</p></li> <li>case执行结束，kill掉第一步中的命令</li> <li>分析收集到的dat文件，使用jscharts绘出走势图</li> </ul> <h2>脚本</h2> <h3>cpu</h3> <p>使用top命令不断查看各进程的cpu占用</p> <h4>linux</h4> <p>get-android-cpu.sh</p> <pre><code> #!/bin/sh #path--target/android-info/mem/dat cd ../../../ mkdir -p target/android-info/cpu/dat mkdir -p target/android-info/cpu/html cp src/main/resources/jscharts.js target/android-info/cpu/html cd target/android-info/cpu/dat while true do adb shell top -n 1| awk '{print $3" "$10}' >> cpu.dat sleep 15 done </code></pre> <h4>windows</h4> <p>get-android-cpu.bat</p> <pre><code> cd ..\\..\\jenkins\\workspace\\android-info-end3 mkdir target\\android-info\\cpu\\dat mkdir target\\android-info\\cpu\\html copy src\\main\\resources\\jscharts.js target\\android-info\\cpu\\html cd target\\android-info\\cpu\\dat :run adb shell top -n 1 | awk "{print $3\\" \\"$10}" >> cpu.dat ping 127.0.0.1 -n 15 > null goto run </code></pre> <h3>memory</h3> <p>使用ps命令不断查看各进程的内存占用</p> <h4>linux</h4> <p>get-android-mem.sh</p> <pre><code> #!/bin/sh #path--target/android-info/mem/dat cd ../../../ mkdir -p target/android-info/mem/dat mkdir -p target/android-info/mem/html cp src/main/resources/jscharts.js target/android-info/mem/html cd target/android-info/mem/dat while true do adb shell ps | awk '{print $5" "$9}' >> mem.dat sleep 15 done </code></pre> <h4>windows</h4> <pre><code> cd ..\\..\\jenkins\\workspace\\android-info-end3 mkdir target\\android-info\\mem\\dat mkdir target\\android-info\\mem\\html copy src\\main\\resources\\jscharts.js target\\android-info\\mem\\html cd target\\android-info\\mem\\dat :run adb shell ps | awk "{print $5\\" \\"$9}" >> mem.dat ping 127.0.0.1 -n 15 > null goto run </code></pre> <h3>流量</h3> <p>android 4.0以上版本可以用<code>/proc/uid\_stat/$uid/tcp\_rcv</code>和<code>/proc/uid\_stat/$uid/tcp\_snd</code>来获取某个程序的上下行流量；而4.0以下版本要用<code>cat /proc/$pid/net/dev</code>来查看上下行流量。uid和pid的关系，可以从<code>/data/system/packages.list</code>这个文件中获取。</p> <h4>linux</h4> <p>判断android api level：</p> <pre><code> #!/bin/sh #android 4.0以上和4.0以下方法不同 #get android sdk level apileveltemp=\`adb shell getprop | grep ro.build.version.sdk\` apilevel=${apileveltemp:25:2} chmod +x \*.sh echo "android api level:"$apilevel if \[ $apilevel -gt 14 \] then ./get-android-net-gt-4.0.sh elif \[ $apilevel -lt 14 \] then ./get-android-net-lt-4.0.sh fi </code></pre> <p>get-android-net-gt-4.0.sh</p> <pre><code> #!/bin/sh #android api level great than 14(android 4.0) #path--target/android-info/net/dat cd ../../../ mkdir -p target/android-info/net/dat mkdir -p target/android-info/net/html cp src/main/resources/jscharts.js target/android-info/net/html cd target/android-info/net/dat cd .. echo "adb pull/data/system/packages.list--start" adb pull /data/system/packages.list cd dat while true do echo "get net info from /proc/uid-stat/$uid" for i in \`adb shell ls /proc/uid\_stat\` do #delete the Enter character uid=\`echo $i | tr -d \["\\r\\n"\]\` adb shell cat /proc/uid\_stat/$uid/tcp\_rcv >> $uid"\_recv.dat" adb shell cat /proc/uid\_stat/$uid/tcp\_snd >> $uid"\_snd.dat" done sleep 15 done </code></pre> <p>get-android-net-lt-4.0.sh</p> <pre><code> #!/bin/sh #path--target/android-info/net/dat cd ../../../ mkdir -p target/android-info/net/dat mkdir -p target/android-info/net/html cp src/main/resources/jscharts.js target/android-info/net/html cd target/android-info/net/dat #get /proc/$pid/net/dev while true do #get pid for i in \`adb shell ps | awk '{print $2}'\` do pid=\`echo $i | tr -d \["\\r\\n"\]\` echo $pid adb shell cat /proc/$pid/net/dev | grep wlan | awk '{print $2" "$10}' >> $pid"\_net.dat" done sleep 15 done </code></pre> <h4>windows</h4> <p>bat命令不熟，不知道如何在windows下实现linux下地反转义，这里用java代码实现。</p> <pre><code> import java.io.\*;
