如何在Ember Model单元测试中检查属性属性类型？

npm install --save-dev qunit ember-qunit ember-test-helpers

import { module, test } from 'qunit';
import { setupTest } from 'ember-qunit';
import { setupRenderingTest } from 'ember-qunit';
import { render } from '@ember/test-helpers';
import hbs from 'htmlbars-inline-precompile';

module('Unit | Model | my-model', function(hooks) {
  setupTest(hooks);
});

test('it has the correct attribute types', function(assert) {
  const model = this.owner.lookup('service:store').createRecord('my-model');

  assert.equal(typeof model.get('attribute1'), 'string', 'attribute1 should be a string');
  assert.equal(typeof model.get('attribute2'), 'number', 'attribute2 should be a number');
  assert.equal(typeof model.get('attribute3'), 'boolean', 'attribute3 should be a boolean');
});
