Please don't delete this unit test - this is the only test that actually does an
end-end test of power measurement.
If this doesn't make sense for Android then you can just move this to be Mac
only.

Done.

-    # Tests that the act of monitoring power doesn't blow up.
-    backend = factory.GetPlatformBackendForCurrentOS()
-    if not backend.CanMonitorPowerSync():
-      logging.warning('Test not supported on this platform.')
-      return
-
-    output = backend.MonitorPowerSync(1)
-    self.assertTrue(output.has_key('power_samples_mw'))
-    self.assertTrue(output.has_key('identifier'))
