Class TestSupportBinder

java.lang.Object

org.springframework.cloud.stream.test.binder.TestSupportBinder

All Implemented Interfaces:

Binder<org.springframework.messaging.MessageChannel,ConsumerProperties,ProducerProperties>

public class TestSupportBinder
extends Object
implements Binder<org.springframework.messaging.MessageChannel,ConsumerProperties,ProducerProperties>

A minimal binder that

• does nothing about binding consumers, leaving the channel as-is, so that a test author can interact with it directly,
• registers a queue channel on the producer side, so that it is easy to assert what is received.
