Stubbing out after_create AR method?

I have a Premise model with an after_create method, along the lines of:

class Premise < ActiveRecord::Base

after_create :etl_attributes

end

In production code, etl_attributes accesses the web. For testing I’m
using WebMock and VCR in cases where I want to test the etl_attributes
function – works like a champ.

For all other tests, I want to create a real Premise object (I need it
for HABTM associations), but I want to stub out the call to
etl_attributes. My problem is that I haven’t figured out the right way
to do so. The following DOESN’T work (it should be clear that I’m using
FactoryGirl as well):

  mock_model(Premise)
  Premise.stub!(:etl_attributes)
  @premise = Factory.create(:premise)

… this still calls etl_attributes and WebMock gets appropriately mad.

What am I missing?

etl_attributes is an instance method, not a class method. So, you want
to stub the method on the Premise instance. Since you’re using rspec-
mocks, I would recommend something like this:

@premise = Factory.build(:premise)
@premise.stub(:etl_attributes)
@premise.save!

Perhaps one way to approach this is to have WebMock return an
appropriate success message in response to the network call that
:etl_attributes makes.

Ah - good point. With all the options for stubbing and mocking, I’d
forgotten that one. Factory Girl is creating premise objects that will
generate different URLs, but I can use the regex option for WebMock to
catch them.

Thanks for getting me unstuck!
