There are a number of useful pieces of test code that allow the Android VR instrumentation tests to interact with the native UI, such as reliably clicking on elements or waiting for elements to reach a particular visibility state.
This functionality is not currently available in the Windows browser test version of the XR test framework, but should be relatively easy to port since the same underlying code is used for handling UI in production.
