I need to connect Android phone to my DUT through USB and I have to connect and disconnect the device, and I need to send/receive data from phone to DUT through phone UI, To automate this I have used adb through wifi, and to disconnect device from DUT I am disabling and enabling USB debugging. While doing that my adb connection I am loosing adb connection also, how can I automate this scenario?
And I am using AndroidViewClient to automate the android.
AndroidViewClient's successor Culebra Tester uses a network connection and a RESTful API to interact with the DUT, then you would be able to disconnect the device from USB after the network service has been started.
More information on Culebra Tester can be found on its public github site or wiki.
