[erlang-questions] Module mock-up's

[Peter Mechlenborg]

Hi,

When writing tests I often find that I want to test the module that I 
working on, in isolation from the rest of the system.
In the past I have sometimes created mock-up processes, for the parts of 
my system that interacts with the module I'm testing.  This works well 
for some cases, but normally processes are encapsulated by a module, and 
what I really want to do is to create a mock-up of the module instead of 
the process.

I haven't found anything with Google, and before I start trying to 
implementing a module-mock-up library, I would like to know if anyone 
have done anything similar, creating mock-up modules?

I would also like to know if I'm missing something simple - how do you 
guys normally test Erlang code that depends on other modules, without 
creating a complete integration test?.  In other words I guess my 
question is, how to do unit tests at the level of modules en Erlang?

Sincerely your,
