请教下 case 内的 py 脚本有啥要求

-- encoding=utf8 --

author = "qiuyunxia"

from airtest.core.api import *

auto_setup(file)

from poco.drivers.android.uiautomation import AndroidUiautomationPoco
poco = AndroidUiautomationPoco(use_airtest_input=True, screenshot_each_action=False)

dev=connect_device("android:///988bdc454835315257")

dev.stop_app("com.unity3d.ads.example.creative")
dev_list =device()
print(dev_list.list_app())
dev.start_app("com.unity3d.ads.example.creative")
poco("com.unity3d.ads.example.creative:id/unityads_example_initialize_button").click()

snapshot()
poco("com.unity3d.ads.example.creative:id/unityads_example_interstitial_button").click()
sleep(4.0)
snapshot()
snapshot()

wait(Template(r"tpl1547966723580.png", record_pos=(0.005, 0.828), resolution=(1080, 2220)))
touch(Template(r"tpl1547966742057.png", record_pos=(0.005, 0.847), resolution=(1080, 2220)))

sleep(1.0)
snapshot()

类似这样子不可以？

运行一直显示 case 为 0,我是用的 air 作为后缀查找的，麻烦大神帮看下
