APP性能测试——热启动耗时测试

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

    :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):
