[erlang-questions] how: Mock processes in a test setup

[Christian S]

Hi, I'm looking at a java testing tool called EasyMock. It allows you
to create an object that adheres to a java interface, but set it up to
what calls (their order) it should expect, then throw it into a test
scenario to see if expectations are met.

I wonder, have someone attempted to implement something similar in Erlang?
