Mock ember-data object factory - Use mirage fixtures (or any other plain old JS object) to mock Ember Data models in component integration tests. See also ember-cli-mirage-object-factory.js - https://gist.github.com/jeradg/6043ba31d831633ce4e3

ember-data-model-mock.js

// tests/helpers/model-mock.js
export function modelMock(attrs) {
  const emberDataRecordAttrs = {
    isValid: true,
    isNew: false
  };

  return Ember.Object.extend(emberDataRecordAttrs)
    .create(attrs);
}

// In your integration test.
// fixtureArray just exports an array of POJOs.
import fixtureArray from 'frontend/mirage/fixtures/something';
import modelMock from 'frontend/tests/helpers/model-mock';

const something = modelMock(fixtureArray[0]);
this.set('model', something);
this.render(hbs`{{my-component model=model}}`);
