Can you test a model in ember without using ds?

I'm getting the following error:

ReferenceError: DS is not defined

Which is understandable considering I'm not using DS. Just wondering if I can run a model test without using DS. It looks like the test helper moduleForModel works with DS as a default, can I alter this method or replace it with something which will work?

Here's what my model looks like:

export default Ember.Object.extend({ accounts: null, isaccountProductsOpen: false, ... }
