Embedded broker as maven dependency #19

Problem or use case

I would like to test my mqtt client/broker setup using JUnit tests.
Since it is cumbersome to start a broker before running the tests, an embedded MQTT 5 compliant broker would ease up the testing.

Preferred solution or suggestions

  • HiveMQ broker as maven dependency
  • Documentation on how to start the broker within a running Java process (e.g. Junit test)

Hi @dowhiletrue,
Thank you for your feature request.

We see the need for something like that, but are right now not sure how to best tackle the issue. Internal considerations are ongoing at the moment.

We will keep the issue open and track progress once decisions are made.

Kind regards

@sauroter I see some places (like this one) where an embedded mode is mentioned. However I can't find any documentation about it. Does the embedded mode still exist?

I am also interested in this feature. I would prefer it be compatible with Spring (or at least not preclude it), so I can integrate with other standard systems (logging, actuator, RestTemplate, caching, permissions, spring security, maybe jms...). Eg. for implementing hivemq extensions. While some of this can be done by splitting things into microservices, integration tests are much easier if I can recombine all that into a compound application.

I guess I could modify
