test.subscriber_failed: Subscriber failed for good during a test

Subscriber failed for good during a test.

Area 13, Testing; not declinable; the next step is usually the agent's.

A delivery between the test's steps failed for good, or stopped as diverged, its rerun no longer matching the record of its steps: here its subscriber's action refuses with a failure not worth retrying. The report names the event, the subscriber and the attempt, then the failure as test.unexpected_failure shows one, at the step whose events were being delivered:

example

use post/entities { Parcel, ParcelNotFound }use post/types { Address }use post/failures { NoSuchPlace }/// Labels a parcel for its round.action label(parcel_id: Parcel.id, address: Address) fails ParcelNotFound, NoSuchPlace -> Unit {    if (address == "The Moon") {        reject NoSuchPlace {}    }    attempt Parcel.update(parcel_id) {        set: {            labelled: true        }    }}

example

use post/actions { label }use post/events { ParcelHandedIn }/// Labels each parcel handed in.subscriber label_handed_in {    on: ParcelHandedIn    run: label(event.parcel_id, event.address)}

example

use post/entities { Parcel }test "a parcel for the moon is taken in" {    var parcel: Parcel = hand_in("The Moon")    assert parcel.labelled == false}
