Overview

In App Center Test, devices will automatically sleep if they do not receive a UI interaction every so often.
​
This means waiting very long times between UI interactions can sometimes cause test failures.
​
The limits are as follows:

  • Android - 10 minutes

  • iOS - 5 minutes

These limits are used because they are generally the maximum sleep limits available on each platform without leaving devices on indefinitely.
​
Indefinite operation this way could cause other problems in our device cloud.
​

Alternative approaches

If your testing scenario requires delays near to or exceeding the above limits, then there are a couple general options to workaround:

  • You can add one or more UI gestures during the wait time to prevent the device from sleeping. 

  • You could mock or simulate the wait time in some fashion for your test, rather than waiting for the full execution to complete normally.
