<h1>Description</h1>
|
|
<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).
|
