The Rabbit MQ Message Listener is a custom message listener extension for Parasoft Virtualize. The listener connects to a Rabbit MQ broker and consumes messages on a specified queue. Depending on the mode of operation (passthrough or virtualize), the messages are forwarded to the real backend system or forwarded to Virtualize, respectively. This listener assumes the publisher uses the Reply To field to define the queue/routing key that will be used when sending the response. The listener also has options to enable the creation of the reply to queue on the fly or to use a predefined reply - to queue.
Implementation
The Rabbit MQ Message Listener is implemented as com.parasoft.virtualize.listener.rabbitmq-<version>.jar, which depends upon Rabbit MQ AMQP Client 5.2.0 (amqp-client-5.2.0.jar). This dependency is packaged with the distribution.
