def send_test_event_notification(Notification=None, TestEventType=None):
    """
    The SendTestEventNotification 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.
