Before writing specs for a one-to-many relationship between two

DRY way):
http://www.ruby-forum.com/topic/126993
Are those two methods currently the accepted "best practice" for
mocking and stubbing calls such like these?:
@properties = @user.properties
@property = @user.properties.new
@property = @user.properties.find_by_id params[:id]
Thanks,

I like to place this in my spec_helper.rb:
module Spec
module Mocks
module Methods
def stub_association!(association_name, methods_to_be_stubbed = {})
mock_association = Spec::Mocks::Mock.new("#{association_name}
association")
methods_to_be_stubbed.each do |method, return_value|
mock_association.stub!(method).and_return(return_value)
end
self.stub!(association_name).and_return(mock_association)
mock_association
end
end
end
end
The you can say stuff like:
@user.stub_association!(:properties, :new => mock_model(Property),
:find_by_id => mock_model(Property))
HTH,
Ben
That's very similar to Matthew Heidemann's #stub_association! . I
can't say who wrote it first, though =) Regardless, that's what I've
been using, and find it to be quite efficient.

Probably Matt.. I can't remember who posted it first... But I got it
from the list a while ago and it has been very useful in a lot of my apps.
