Send a test event

Deliver a signed sample event to an endpoint to check your handler.

Sends a signed sample event and returns the delivery. The payload has test: true and a made-up subject whose ID contains _test_, with only that ID in data, so your handler can tell it apart and nothing in your business changes. A test delivery goes out once and isn't retried.
