Unit Testing Models with Associations/Relationships Fail

[f3ndot]

When unit testing a model that makes use of DS.belongsTo() the createRecord() fails with the following error:

Error: No model was found for 'Client'

It appears that in order to create a record of a model, it expects its associated or related model to already exist. What's going on?

---

Here are the models and test

/app/models/client.js:

export default DS.Model.extend({
  name: DS.attr('string'),
  invoices: DS.hasMany('Invoice'),
});

/app/models/invoice.js:

export default DS.Model.extend({
  amount: DS.attr('number'),
  discountTotal: DS.attr('number'),

  totalAmount: function() {
    return this.get('amount') - this.get('discountTotal');
  }.property('amount', 'discountTotal'),

  client: DS.belongsTo('Client'),
});

tests/models/invoice.js:

import { test, moduleForModel } from 'ember-qunit';

moduleForModel('invoice', 'Invoice Model');

test('totalAmount computed property considers discounts', function() {
  // this.subject() is aliased more or less to createRecord() for the
  // invoice model. See module-for-model.js in ember-qunit.
  //
  // Attempting to run the below function throws the error.
  var invoice = this.subject({
    id: 1,
    amount: 50.0
    discountTotal: 10.0
  });

  equal(invoice.get('totalAmount'), 40.0);
});

It's worth mentioning that there are no FIXTURES array defined for the models, since thus far testing I've done has been using an api-stub server in integration testing. Not sure if that's a contributing factor.
