rspec users - Feb 2009 - How to return a value passed by ref to a method

Hi,

I have a recursive method and I want to mock a var passed by ref.
Object.should_receive(:my_method).and_return"by_ref"(@value)

Something like that.

Any idea?

AFAIK, Ruby has no language construct for "by_ref/by_val," so
I''m not
sure what you''re getting at here. Are you saying that you want the
method to return the value of an @value instance variable in the
object?

Often a way to spec a recursive function is to alias it, and have the 
recursive call call the alias.  So if you want to check the recursion, 
you could do something like this (in a lispy-type ruby):
