test_RequestIdle_behaviour.xml

<?xml version="1.0"?>
<!--
This XML is a simple test to validate the behaviour of requestIdle.

The supervisor will print "State 0 from device" followed by "State 1 from device" 
if requestIdle is respected.

Otherwise, the Supervisor will print "State 0 from device" followed by two prints
of "State 1 from device". The Supervisor will then exit via an API call.
