I've been spec'ing for a long time, but I've never discovered the
answer to this, so a definitive answer would be great!
Whats the best way to spec a method which basically filters an
association?
class Thing < ActiveRecord::Base
has_many :others
def foos
others.all(:conditions => { ... })
end
end
I don't like the idea of creating a load of associated records in my
spec and testing the returned result as I am not testing the
associated model and as such would prefer any references to it to be
mocked out, so the best I can some up with is this super lame test
which is clearly way too implementation specific and essentially
useless.
describe Thing do
describe 'foos' do
before :each do
@thing = Thing.new
@others_proxy = mock('others proxy')
@others_proxy.stub!(:all)
@thing.stub!(:others).and_return(@others_proxy)
end
it 'should return the associated others which meet the conditions'
do
@others_proxy.should_receive(:all).with({ :conditions => ' ...
' })
@thing.foos
end
end
end
So what's the best practice in this case?

Thanks.
P.S. This is old code I've inherited so I'm just trying to retrofit
RSpec 1.3x to it before I start refactoring and bringing up to date
with rails 3/rspec 2, so basically what I mean is what's the answer if
the model simply is how it is and can't be changed?
