Trying to mock "new" through an association

Question

This is in my controller

@business = @current_user.businesses.new(params[:business])

@businesses is an array of business objects and I'm unsure of how to mock this cascade of calls.

Answer 1

Here is one way to do it. The 'businesses' part of it is an association proxy. So usually mock it like this:

business = Business.new
businesses_proxy = mock('business association proxy', :new => business)
@current_user.should_receive(:businesses).and_return(businesses_proxy)

or more explicit

business = Business.new
businesses_proxy = mock('business association proxy')
businesses_proxy.should_recieve(:new).and_return(business)
@current_user.should_receive(:businesses).and_return(businesses_proxy)
