Anyone know of a good way to unit test Scala actors? In the general sense I have an actor that receives a message and will send out other messages in response. This is done on multiple threads, and an actor that is not correct may either send the wrong messages or no message at all. I need a simple way of creating a mockup actor that send and receives messages to the actor being tested. Any experiences in this area?
Because of the dynamic nature of actor-style message passing, mocking actors is usually no trouble at all. Just create an actor which receives the desired message and you’re home free. You will of course need to ensure that this mock actor is the one to which messages are passed, but that shouldn’t be a problem as long as the actor you are attempting to test is reentrant.
