簡介

APP效能測試一般對以下幾個方面進行測試：
1.啟動時間（可以通過本工具測試）；
2.CPU的佔用（可以通過本工具測試）；
3.記憶體的佔用（可以通過本工具測試）；
4.流量的耗用（可以通過本工具測試）；
5.電量的耗用（使用者實際使用中感知即可）。
 
除了可以做以上這幾個專項測試外，本工具還能進行monkey測試等等。
可以結合工作需要靈活自定義指令碼，封裝成自己工作中常用的工具。
工具的實現是基於adb和PowerShell的，支援adb通過USB和WIFI兩種方式連線手機進行操作。

前置工作

1. 需要安裝adb；

2. 需要本機設定PowerShell指令碼執行策略。

指令碼示例

PowerShell例子如下（不斷更新）：

#獲取當前app包名和活動名

Function GetPkgAndActName () {

    #確保app處於啟用狀態

    $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

}

#獲取當前流量統計資訊

Function GetCurrFlow () {

    #確保app處於啟用狀態

    $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

}

#轉換檔案大小單位

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)

}

可以根據實際測試過程中反覆手點的過程進行組裝調配。比如在反覆測試登入的情況下，就要反覆輸入密碼，如果來回用手點就比較麻煩，用這個小工具的話就非常輕鬆了，按一下上再敲一下回車就搞定了。
