# 启动app应用

# 设置app应用后台运行

    cold_boot_time = shell(cmd_start)[10:].strip()
    return int(cold_boot_time)

# 获取热启动时间
def get_hot_boot_time(package_name, launch_activity, device_id = ''):
    set_activity_backup(package_name, launch_activity, device_id)
    if device_id != '':
        cmd_start = "adb -s %s shell am start -W %s | grep 'WaitTime'" % (device_id, package_name + "/" + launch_activity)
    else:
        cmd_start = "adb shell am start -W %s | grep 'WaitTime'" % (package_name + "/" + launch_activity)
    cold_boot_time = shell(cmd_start)[10:].strip()
    return int(cold_boot_time)

# 执行测试,times为次数,结果取平均值
def run_test(times):
    cold_time = []
    hot_time = []
    for i in range(times):
        cold_time.append(get_cold_boot_time('com.tencent.mobileqq', '.activity.SplashActivity'))
        hot_time.append(get_hot_boot_time('com.tencent.mobileqq', '.activity.SplashActivity', 'abbed25'))
    res_cold_time = 0
    res_hot_time = 0
    print("cold_time = " + str(cold_time))
    print("hot_time = " + str(hot_time))
    for i in cold_time:
        res_cold_time = res_cold_time + i
    print('average cold_time: ' + str(res_cold_time / times) + ' ms')
    for i in hot_time:
        res_hot_time = res_hot_time + i
    print('average hot_time: ' + str(res_hot_time/times) + ' ms')

# 执行10次
run_test(10)

测试结果:

cold_time = [395, 341, 312, 312, 324, 312, 321, 333, 332, 323]
hot_time = [46, 57, 64, 60, 40, 46, 25, 88, 53, 56]
average cold_time: 330 ms
average hot_time: 53 ms

感谢感谢!刚好需要判断 APP 在前端还是后端

adb 时间差距比较大

windows 下貌似不能运行啊,sed 不是内部命令,我自己添加 sed.exe 后,cmd 内可以使用 sed,在代码运行依然不能成功

grep 也不是,考虑兼容性的话字符串处理都应该在 python 里做,而不是 shell

grep 这个可以把 shell 后的语句全部双引号就行,但是 sed 是真的不行

window 的我没试过呢,要不把得到的 adb 结果放在 Python 中处理咯?

楼主好,这个方法能封装直接调用吗

可以的,自己改成想要的样子就行了
