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 = GetPkgAndActName
    $pkgName = ($pkgAndActName.split("/"))[0]
    $activityName = ($pkgAndActName.split("/"))[1]
    $userId = (((((adb shell dumpsys package $pkgName | findstr userId).Trim()).split("="))[1]).split(" "))[0]
    $rets = adb shell cat /proc/net/xt_qtaguid/stats | findstr $userId
    foreach ($ret in $rets)
    {
        $spices = ($ret.Split(" "))
        $flow += [int]$spices[5]+[int]$spices[7]
    }
    $flow/1000
}

#转换文件大小单位
function Convert-Size {
    [cmdletbinding()]
    param(
        [validateset("Bytes","KB","MB","GB","TB")]
        [string]$From,
        [validateset("Bytes","KB","MB","GB","TB")]
        [string]$To,
        [Parameter(Mandatory=$true)]
        [double]$Value,
        [int]$Precision = 4
    )
    switch($From) {
        "Bytes" {$value = $Value }
        "KB" {$value = $Value * 1024 }
        "MB" {$value = $Value * 1024 * 1024}
        "GB" {$value = $Value * 1024 * 1024 * 1024}
        "TB" {$value = $Value * 1024 * 1024 * 1024 * 1024}
    }
    switch ($To) {
        "Bytes" {return $value}
        "KB" {$Value = $Value/1KB}
        "MB" {$Value = $Value/1MB}
        "GB" {$Value = $Value/1GB}
        "TB" {$Value = $Value/1TB}            

    }
    return [Math]::Round($value,$Precision,[MidPointRounding]::AwayFromZero)
}

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。
