Do I need to test the domain services in Domain driven design?

Question

I am developing a console application using domain driven design, i tried to keep the domain logic as much as possible into domain entities, but some how, some logic leaked into domain services, so now, do i need to test the domain services, if yes how to do it?

Answer 1

Yes, if they contain logic, they have to be tested.

If the service was properly decoupled, it should be possible to test it with unit tests and dependency injection.
