Ember.js: How to integration test components that interact with ember-data models

I'm building a relatively straight-foward comment-list component. I want to pass in the commentable model (say a Post) and have the component take care of creating, editing, deleting comments. Right now I pass around all the various actions and it's been extremely brittle.

How do I create a true ember data model in a component integration test?

My immediate thought was to import the model then .create({}) it but that errors with use this.store.createRecord() instead

/* jshint expr:true */
import { assert } from 'chai';
import { describeComponent, it } from 'ember-mocha';
import hbs from 'htmlbars-inline-precompile';
import Post from 'ownersup-client/post/model';

describeComponent( 'comment-list', 'Integration: CommentListComponent', {
    integration: true
  },
  function() {
    it('renders all of the comments', function() {
      const model = Post.create({ title: 'title' });
      model.get('comments').createRecord({ body: 'One Comment' })

      this.render(hbs`{{comment-list model=model}}`);

      assert.lengthOf(this.$('.comment-list-item'), 1);
    });
  }
);

Anyone have any thoughts?
