-    <p>
-      <strong>This test is only useful on devices that do not have vibration capability</strong>.
-      If your device supports vibration, then <strong>skip</strong> this test. An implementation
-      supporting this API but running on a device that cannot vibrate must silently ignore the
-      call (we test that it doesn't throw).
