I want to implement integration tests. And I would like to not up RabbitMQ instance for it and the only change I want is to modify connection settings in tests (to use memory instance). Is it possible ?

CodePudding user response：

There is no in-memory instance of RabbitMQ. You could, as pointed out in the comments above, stand up RabbitMQ in a container to run the tests. This is what MassTransit does using GitHub Actions.

MassTransit also has an extensive in-memory transport which can be used for unit tests. The gRPC transport is also designed to be match the RabbitMQ topology, including fanout, direct, and topic exchanges, and can be used without any dependencies.
