Power stress test would be:
-Connect power adapter to device
-Check powerd that the device is charging
-Remove power adapter
-Check powerd that the device is discharging
-Repeat
The test should fail if the powerd status does not correspond to the RPM/PDU
status.
Arguments the test accepts:
-loop_count - number of iterations to go through power on/off and checks
-suspend_time - timeout for suspend wakealarm; default is 0 - no suspending
(for each iteration)
