<p>
The <code>SendTestEventNotification</code> operation causes Amazon Mechanical Turk to send a notification message
as if a HIT event occurred, according to the provided notification specification. This allows you to test
notifications without setting up notifications for a real HIT type and trying to trigger them using the website.
When you call this operation, the service attempts to send the test notification immediately.

@param sendTestEventNotificationRequest
@return Result of the SendTestEventNotification operation returned by the service.
@throws ServiceException
        Amazon Mechanical Turk is temporarily unable to process your request. Try your call again.
@throws RequestErrorException
