ember.js - ember-qunit: 你只能卸载一个不是 inFlight 的记录

Question

我有一些访问商店的单元测试。我会认为这会很好，只要我将它们包装在运行回调中。不幸的是，情况并非如此。我收到此错误:

afterEach 在 #foo 上失败:断言失败:您只能卸载不在飞行中的记录。

据我了解，这正是 run应该是预防。我的测试看起来像这样:

test('#foo', function(assert) {
  var store = this.store();
  var model = this.subject();

  Ember.run(function() {
    var secondModel = store.createRecord('secondModel', { foo: 'bar' });
    model.set('secondModel', secondModel);
    var foo = model.get('secondModelFoo');

    assert.equal(foo, 'bar');
  });
});

似乎这不再是 Ember Data v1.13.8 与 Ember v1.13.7 结合的问题。

对于以下设置:

模型/第一个model.js

import DS from 'ember-data';

export default DS.Model.extend({
  secondModel: DS.belongsTo('second-model')
});

模型/第二个model.js

import DS from 'ember-data';

export default DS.Model.extend({
  foo: DS.attr('string')
});

测试/单元/模型/第一个模型-test.js

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

moduleForModel('first-model', 'Unit | Model | first model', {
  // Specify the other units that are required for this test.
  needs: ['model:second-model']
});

test('it exists', function(assert) {
  var model = this.subject();
  // var store = this.store();
  assert.ok(!!model);
});

test('#foo', function(assert) {
  var store = this.store();
  var model = this.subject();

  Ember.run(function() {
    assert.expect(1);

    var secondModel = store.createRecord('second-model', { foo: 'bar' });
    model.set('secondModel', secondModel);
    var foo = model.get('secondModel.foo');

    assert.equal(foo, 'bar');
  });
});
