Is it possible to have both Mobile and Web scripts for the same projects where Mobile app function is depend on the web part to be sync with the each other.But the issue i am facing in the driver conflict between them both.can it be possible to have it on the same project and performs the Test Simultaneously in the same Test case.
One answer may depend on how the behavior is delivered to the device. If the behavior is the same for both devices (delivered from a server back end, say), then your test objective is to verify that both can reach the behavior. In that case, I believe you have different tests - one test for each device because of UI differences.
If your test objective is to evaluate just the behavior, the device does not matter and you can evaluate the behavior independently of the device.
