How to return a value passed by ref to a method

Testing RSpec

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?

Hello,

This is a question from one of my teammate, I’ll revalidate tomorrow
with
him what is his issue.

Thank you

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):
