把工作中用到的用來測試、收集Android客戶端性能數據的Python代碼整理了一下，涉及到PSS、CPU、啟動時間、流量、電量，用os.popen()方法執行adb命令並獲取執行結果，用csv文件來存儲數據。得到數據後可以做成可視化的圖標，方便得出測試結論。

獲取CPU的代碼：

 1 #/usr/bin/python
 2 #encoding:utf-8
 3 import csv
 4 import os
 5 import
 
 time
 6 
 7 #控制類
 8 class Controller(object):
 9     def __init__(self, count):
10         self.counter = count
11         self.alldata = [("timestamp", "cpustatus")]
12 
13     #單次測試過程
14     def testprocess(self):
15         result = os.popen("adb shell dumpsys cpuinfo | grep com.android.browser")
 
16         for line in result.readlines():
17             cpuvalue =  line.split("%")[0]
18 
19         currenttime = self.getCurrentTime()
20         self.alldata.append((currenttime, cpuvalue))
21 
22     #多次執行測試過程
23     def run(self):
24         while self.counter >0:
25             self.testprocess()
 
26             self.counter = self.counter - 1
27             time.sleep(3)
28 
29     #獲取當前的時間戳
30     def getCurrentTime(self):
31         currentTime = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
32         return currentTime
33 
34     #數據的存儲
35     def SaveDataToCSV(self):
36         csvfile = file(‘cpustatus.csv‘, ‘wb‘)
37         writer = csv.writer(csvfile)
38         writer.writerows(self.alldata)
39         csvfile.close()
40 
41 if __name__ == "__main__":
42     controller = Controller(10)
43     controller.run()
44     controller.SaveDataToCSV()

獲取PSS的代碼：

 1 #控制類
 2 class Controller(object):
 3     def __init__(self):
 4         #定義收集數據的數組
 5         self.alldata = [("id", "vss", "rss")]
 6 
 7     #分析數據
 8     def analyzedata(self):
 9         content = self.readfile()
10         i = 0
11         for line in content:
12             if "com.android.browser" in line:
13                 print line
14                 line = "#".join(line.split())
15                 vss = line.split("#")[5].strip("K")
16                 rss = line.split("#")[6].strip("K")
17 
18                 #將獲取到的數據存到數組中
19                 self.alldata.append((i, vss, rss))
20                 i = i + 1
21 
22     #數據的存儲
23     def SaveDataToCSV(self):
24         csvfile = file(‘meminfo.csv‘, ‘wb‘)
25         writer = csv.writer(csvfile)
26         writer.writerows(self.alldata)
27         csvfile.close()
28 
29     #讀取數據文件
30     def readfile(self):
31         mfile = file("meminfo", "r")
32         content = mfile.readlines()
33         mfile.close()
34         return  content

獲取啟動時間的代碼：

 1 class App(object):
 2     def __init__(self):
 3         self.content = ""
 4         self.startTime = 0
 5 
 6     #啟動App
 7     def LaunchApp(self):
 8         cmd = ‘adb shell am start -W -n com.android.browser/.BrowserActivity‘
 9         self.content=os.popen(cmd)
10 
11     #停止App
12     def StopApp(self):
13         #cmd = ‘adb shell am force-stop com.android.browser‘
14         cmd = ‘adb shell input keyevent 3‘
15         os.popen(cmd)
16 
17     #獲取啟動時間
18     def GetLaunchedTime(self):
19         for line in self.content.readlines():
20             if "ThisTime" in line:
21                 self.startTime = line.split(":")[1]
22                 break
23         return self.startTime
24 
25 #控制類
26 class Controller(object):
27     def __init__(self, count):
28         self.app = App()
29         self.counter = count
30         self.alldata = [("timestamp", "elapsedtime")]
31 
32     #單次測試過程
33     def testprocess(self):
34         self.app.LaunchApp()
35         time.sleep(5)
36         elpasedtime = self.app.GetLaunchedTime()
37         self.app.StopApp()
38         time.sleep(3)
39         currenttime = self.getCurrentTime()
40         self.alldata.append((currenttime, elpasedtime))
41 
42     #多次執行測試過程
43     def run(self):
