Package org.axonframework.test.saga

Interface WhenAggregateEventPublisher

public interface WhenAggregateEventPublisher
Interface to an object that publishes events on behalf of an aggregate, recording what the Saga does in reaction.

Axon Framework 5 has no DomainEventMessage, so the aggregate type, aggregate identifier and sequence number travel on the processing context rather than on the message. A Saga reads them as AggregateType, SourceId and SequenceNumber handler parameters, which is where Axon Framework 4 read them from the message. A handler declaring one of those is only invoked for an event that has an aggregate, so an event published through FixtureConfiguration.givenAPublished(Object) does not reach it.
