用adb命令组装PowerShell实用小工具——Android测试小助手
[本文出自天外归云的博客园]
简介
APP性能测试一般对以下几个方面进行测试：
1.启动时间（可以通过本工具测试）；
2.CPU的占用（可以通过本工具测试）；
3.内存的占用（可以通过本工具测试）；
4.流量的耗用（可以通过本工具测试）；
5.电量的耗用（用户实际使用中感知即可）。
除了可以做以上这几个专项测试外，本工具还能进行monkey测试等等。
可以结合工作需要灵活自定义脚本，封装成自己工作中常用的工具。
工具的实现是基于adb和PowerShell的，支持adb通过USB和WIFI两种方式连接手机进行操作。
前置工作
1. 需要安装adb；
2. 需要本机设置PowerShell脚本运行策略。
脚本示例
PowerShell例子如下（不断更新）：
#获取当前app包名和活动名 Function GetPkgAndActName () { #确保app处于激活状态 $a = adb shell dumpsys window windows|findstr Focu $b = $a -like "*mCurrentFocus*" $b = $b.Trim() $startIndex = $b.IndexOf("{") $endIndex = $b.IndexOf("}") $pkgAndActName = (($b.Substring($startIndex+1,$endIndex-$startIndex-1)).split(" "))[2] return $pkgAndActName } #获取当前流量统计信息 Function GetCurrFlow () { #确保app处于激活状态 $pkgAndActName =

可以根据实际测试过程中反复手点的过程进行组装调配。比如在反复测试登录的情况下，就要反复输入密码，如果来回用手点就比较麻烦，用这个小工具的话就非常轻松了，按一下上再敲一下回车就搞定了。
