You can test WebSphere® MQ on z/OS® by using the IBM® DevOps Test Integrations and APIs (Test Integrations and APIs) MQ agent module. You can record at the transport level or operation level when running the agent with a single queue manager. If you have a queue sharing group and if you choose to run an instance of the agent for each queue manager within the queue sharing group, you can record shared queues using mirror queue recording. You can also virtualize requests to shared queues using fixed queue stubbing.
For information on testing WebSphere MQ on non- z/OS, see Testing with IBM WebSphere MQ messages.
