# 执行10
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

很棒

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?
