APP性能测试——首次启动耗时测试

首次启动耗时：

即第一次安装（清除数据也可以），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

# 测试首次启动时间

# 创建App进程, 加载相关资源, 启动Main Thread, 初始化首屏Activity

def startUpTime(pg_name, pga_name):

    """

    :param device: 设备id

    :param pg_name: 包名

    :param pga_name: activity名称

    """

    wait_time = 5

    try:

        with open('F:/report/firstStartUp.txt', 'wb+') as file:

            su_time = []

            for i in range(30):

                os.popen("adb shell pm clear {}".format(pg_name))  # 清除app缓存

                time.sleep(wait_time)

                # 启动activity

                start = os.popen("adb shell am start -W {}".format(pga_name))

                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

                        su_time.append(int(line[11:]))

                        file.write(('第{}次\n'.format(i + 1)).encode())

                        line += '\n'

                        line = line.encode()

                        file.write(line)

            return su_time

    except os.error as error:

        print(error)

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][:-7]

            return s

        return 0

    except Exception as error:

        print(error)

def main_cold():

    # 取测试机-s

    s = getDev()

    pn = 'sg.partying.ghost.android'

    an = 'sg.partying.ghost.android/com.bb.infinity.InfiActivity'

    print('设备：{},APP包名：{}, activity：{}\n首次启动测试开始...'.format(s,pn, an))

    time_list = startUpTime(pn, an)

    total_time = 0

    for i in time_list:

        total_time += i

    avg_time = total_time / len(time_list)

    print('首次启动平均耗时： {}ms'.format(avg_time))

    with open('F:/report/firstStartUp.txt', 'ab+')as f:

        f.write(('\n设备{}平均首次启动耗时：{}ms'.format(s,avg_time)).encode())

if __name__ == '__main__':

    main_cold()
