问题
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?
回答1:
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')
it's documented at:
http://mocha.rubyforge.org/classes/Mocha/ClassMethods.html#M000001

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
