mocha and nested objects

Question

Excuse if this is a silly question, I am new to mocking.

I am able to use mocha to do things like:

person.expects(:first_name).returns('David')

How can I mock a nested object?

Say I have a Product that belongs to a Person and I want to get the first name of that person.

In my app I might do it like this:

product.person.first_name

How would I get the same result using a mock?

you need define a mock() before and return it when you call person on product


person = mock(:first_name => 'david')
product.expects(:person).return(person)

product.person #=> mockObject
product.person.first_name #=> david

as an alternative to shingara's answer, you could use mocha's any_instance method "which will detect calls to any instance of a class".

Person.any_instance.expects(:first_name).returns('david')
