折腾：
【已解决】给自动测试工具项目代码中加上判断安卓手机设备是否已连接的逻辑
期间，去实现，Mac中用adb connect的方式去连接和检测当前无线WiFi设备是否已连接
src/common/DevicesMethods.py
def connectDevice(self):
"""连接/重连 Android/iOS 设备"""
isConnected = False
if self.isAndroid:
adbConnectCmd = "adb connect %s" % self.device
logging.info("Try connect Android device: %s", adbConnectCmd)
# os.system(adbConnectCmd) # when failed, will wait too long time: ~ 1 minutes
cmdOutputStr = CommonUtils.get_cmd_lines(adbConnectCmd, text=True, timeout=1)
if cmdOutputStr:
if "connected" in cmdOutputStr:
isConnected = True
elif "failed" in cmdOutputStr:
isConnected = False
else:
isConnected = False
elif self.isiOS:
logging.warning("TODO: add support start iOS device")
return isConnected重试
即可：
[201217 13:24:11][AppCrawler.py 32 ] Android device 192.168.31.84:5555 not connected !
src/AppCrawler.py
# makesure device connected
if self.connectDevice():
logging.info("%s device %s connected", self.platformType, self.device)
else:
errMsg = "%s device %s not connected !" % (self.platformType, self.device)
logging.error(errMsg)
raise Exception(errMsg)重新调试 ：
可以跑出异常了：
发生异常: Exception Android device 192.168.31.84:5555 not connected !
符合预期。
然后对于此处，最开始初始化的时候，是可以加上重试的
# makesure device connected
isConnected = False
MaxRetryNum = 3
curRetryNum = 1
while curRetryNum <= MaxRetryNum:
isConnected = self.connectDevice()
if isConnected:
break
curRetryNum += 1
if isConnected:
logging.info("%s device %s connected", self.platformType, self.device)
else:
errMsg = "%s device %s not connected after %d retry !" % (self.platformType, self.device, MaxRetryNum)
logging.error(errMsg)
raise Exception(errMsg)结果：
[201217 13:29:09][DevicesMethods.py 1896] Try connect Android device: adb connect 192.168.31.84:5555 err=Command 'adb connect 192.168.31.84:5555' timed out after 1 seconds when run cmd=adb connect 192.168.31.84:5555
突然发现，貌似超时时间太短?
又发现，好像不是，1秒足够正常连接了。
发生异常: Exception Android device 192.168.31.84:5555 not connected after 3 retry !
符合预期
那再去把WiFi切换回正常的guest 5G：
再去测试，这下应该能连上才对。
Try connect Android device: adb connect 192.168.31.84:5555
返回：
'connected to 192.168.31.84:5555\n'
是正常连上了。
然后后续也可以获取到phone的name了：
加上代码：
cmdOutputStr = CommonUtils.get_cmd_lines(adbConnectCmd, text=True, timeout=1)
logging.info("console output: %s", cmdOutputStr)
# connected to 192.168.31.84:5555
# already connected to 192.168.31.84:5555输出：
[201217 13:36:18][DevicesMethods.py 1896] Try connect Android device: adb connect 192.168.31.84:5555 [201217 13:36:19][DevicesMethods.py 1899] console output: already connected to 192.168.31.84:5555
即可。
【后记 20201218】
折腾：
【已解决】Mac中如何用adb检查确保USB有线连接安卓手机
期间，进一步优化。
去调试看看
输出：
[201218 16:27:04][DevicesMethods.py 2032] Try connect Android device: adb connect 192.168.31.84:5555 [201218 16:27:05][DevicesMethods.py 2035] console output: already connected to 192.168.31.84:5555
是我们希望的。
最后是：

if "connected" in cmdOutputStr:
isConnectOk = True
elif ("failed" in cmdOutputStr) or ("timed out" in cmdOutputStr):

else:

return isConnectOk调用：
self.device="192.168.31.84:5555" isWiFiConnected = self.androidConnectWiFiDevice(self.device)
即可。
以及相关工具类函数：
CommonUtils.get_cmd_lines
等价于：
中的：getCommandOutput
