usesExplicitRouting

protected abstract boolean usesExplicitRouting()

Implementations should return whether the binder under test uses "explicit" routing (e.g. Rabbit) whereby Spring Cloud Stream is responsible for assigning a partition and knows which exact consumer will receive the message (i.e. honor "partitionIndex") or "implicit" routing (e.g. Kafka) whereby the only guarantee is that messages will be spread, but we don't control exactly which consumer gets which message.

getEndpointRouting

protected String getEndpointRouting(Object endpoint)

For implementations that rely on explicit routing, return the routing expression.

getExpectedRoutingBaseDestination

protected String getExpectedRoutingBaseDestination(String name,
                                                   String group)

For implementations that rely on explicit routing, return the expected base destination (the part that precedes '-partition' within the expression).

getClassUnderTestName

protected abstract String getClassUnderTestName()

extractEndpoint

protected org.springframework.context.Lifecycle extractEndpoint(org.springframework.cloud.stream.binder.Binding<org.springframework.messaging.MessageChannel> binding)
