这里是如何重现的。使用ember-cli
0.44,创建一个新应用,并生成user
和address
模型。他们彼此belongsTo
。
然后,为address
编写一个单元测试,如下所示:
test('it has a user', function() {
var model = this.subject();
var store = this.store();
Ember.run(function() {
var user = store.createRecord('user');
model.set('user', user);
ok(true);
});
});
将needs: ['model:user']
添加到测试中。测试通过了。
现在,输入ember g acceptance-test index
。单位测试打破了模型,就在model.set
行:

有什么想法吗?单元测试中不允许store.createRecord
吗?

事实证明商店引用不同,即使this.store()
看起来像是检索商店的有福方式,但它与用于制作model
的方式不同:
var model = this.subject();
model.store.toString(); //<DS.Store:ember816>
this.store().toString(); //<DS.Store:ember817>
所以,当我尝试使用model.set('relationship'..
时,Ember认为它不是来自同一个商店,并且断言失败了。
使用model.store
似乎可以解决问题。
我认为这是this.store
测试助手中的错误。

对于最新版本的ember-cli,Ember和Ember数据,这个问题没有发生。 Github问题也很接近https://github.com/ember-cli/ember-cli-qunit/issues/42
