APP性能测试——热启动耗时测试

本文主要是介绍APP性能测试——热启动耗时测试，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

热启动耗时：

    即当启动应用时，后台已有该应用的进程（我们模拟按下HOME键），打开软件，直到进入到首页activity页面，并计算耗时。

示例代码：

import os
import time


def hotTime(device, pg_name, pga_name):
    """
    :param device:
    :param pg_name:
    :param pga_name:
    :return:
    """
    # kill 进程
    wait_time = 5
    os.popen("adb -s {} shell am force-stop {}".format(device, pg_name))
    time.sleep(wait_time)
    os.popen("adb -s {} shell am start -W {}".format(device, pga_name))
    time.sleep(wait_time)
    try:
        with open('F:/report/hotTime.txt', 'wb+') as f:
            hot_time = []
            for i in range(30):
                keyEvent(3)  # adb模拟按下Home键
                time.sleep(wait_time)
                start = os.popen("adb -s {} shell am start -W {}".format(device, pga_name))  # 启动activity
                time.sleep(wait_time)
                data = start.readlines()
                for line in data:
                    if "TotalTime:" in line:
                        line = line.strip()
                        print("第{}次TotalTime为:{}ms".format(i+1,line[11:]))
                        if int(line[11:]) == 0:
                            break
                        hot_time.append(int(line[11:]))
                        f.write(('第{}次\n'.format(i + 1)).encode())
                        line += '\n'
                        f.write(line.encode())
            return hot_time
    except os.error as error:
        print(error)


# 获得设备ID
def getDev():
    """
    :return: 获得设备id
    """
    try:
        devices_info = os.popen('adb devices')
        data = devices_info.readlines()
        if len(data) != 0 and data[1].find('device'):
            s = data[1][:-8]
            return s
        return 0
    except Exception as error:
        print(error)


# 模拟发送keyEvent
def keyEvent(keycode):
    """
    :param keycode: 键值
    """
    # KEYCODE_HOME = 3
    # KEYCODE_BACK = 4
    cmd = 'adb shell input keyevent {}'.format(keycode)
    os.popen(cmd)
    time.sleep(1)
