我正在编写Qunit测试来测试Ember模型,但是很难测试具有关系依赖关系的计算属性(计算属性触发另一个模型的计算属性)。
I'm writing Qunit tests to test An Ember model, but having a hard time testing computed properties that have a relation dependency (the computed property triggers another model's computed property).
正在测试的模型(CoffeeScript):
The model that am testing (CoffeeScript):
Customer = DS.Model.extend firstName: DS.attr('string') lastName: DS.attr('string') phones: DS.attr('embedded-list') phone: (-> @get('phones.firstObject.number') ).property('phones.firstObject.number') fullName: (-> [@get('lastName'), @get('firstName')].join(' ') ) ).property('firstName','lastName')会议模型:
Meeting = DS.Model.extend customers: DS.hasMany('customer') startAt: DS.attr('isodate') status: DS.attr() objective: DS.attr() customerPhones: (-> phones = [] @get('customers').forEach (c) -> c.get('phones').forEach (ph) -> phones.push(ph.number) phones ).property('customers.@each.phones') firstCustomer: (-> @get('customers.firstObject') ).property('customers.firstObject') firstCustomerFullName: (-> @get('firstCustomer.fullName') ).property('firstCustomer.fullName')现在,测试 customerPhones 和 firstCustomerFullName 确实让我很难受...
Now, testing customerPhones, and firstCustomerFullName is giving me a real hard time...
我的测试如下:
`import { test, moduleForModel } from 'ember-qunit';` moduleForModel('meeting', 'App.Meeting',{ needs: ['model:customer'] setup: -> Ember.run do (t = @)-> -> customer = t.store().createRecord 'customer', firstName: 'John', lastName: 'Smith', phones:[] customer.get('phones').addObject(Ember.Object.create({tag: 'home', number: '111222333'})) customer.get('phones').addObject(Ember.Object.create({tag: 'work', number: '444555666'})) t.subject().set('customers.content', Ember.ArrayProxy.create({content: []})); t.subject().get('customers.content').pushObject(customer) teardown: -> },(container, context) -> container.register 'store:main', DS.Store container.register 'adapter:application', DS.FixtureAdapter context.__setup_properties__.store = -> container.lookup('store:main') ) test "it's a DS.Model", -> ok(@subject()) test "attributes: can be created with valid values", -> meeting = @subject({objective: 'Follow up'}) Ember.run -> equal(meeting.get('objective', 'Follow up')) test "properties: firstCustomer & firstCustomerFullName & firstCustomerPhone", -> meeting = @subject() Ember.run -> equal(meeting.get('firstCustomer.fullName'), 'Smith John') equal(meeting.get('firstCustomer.phone'), '111222333')现在,我在此测试中使用了一些技术,这些技术是我在Stack Overflow的答案中找到的,但我似乎无法
Now, I used some techniques in this test, that I found in an answer here on Stack Overflow, but I can't seem to find it now.
几天前这很好用,现在(我知道这是胡说八道)无论何时运行测试,都会出错:
That worked perfectly few days ago, now (it seems nonsense I know) whenever I run the test, it errors:
断言失败:您不能在此关系中添加会议记录(仅允许会议)
Assertion Failed: You cannot add 'meeting' records to this relationship (only 'meeting' allowed)
我不知道错误在哪里,也不知道如何解决。
I don't know where the error is, nor how to fix it. Spent all the day monkeying around, No outcome.
我该如何解决?
推荐答案好的,到目前为止,我的评论太多了,所以我要做一个WIP答案。
Okay, what I have so far is too much for a comment, so I'm going to do a WIP Answer.
-
我删除了大多数运行循环,它们仅对于异步进程是必需的。
I removed most of the run loops, they are only necessary for async processes.
我将您的某些计算属性更改为 computed.alias 属性
I changed some of your computed properties to computed.alias properties
phone: (-> @get('phones.firstObject.number') ).property('phones.firstObject.number')到
phone: Emberputed.alias('phones.firstObject.number')
- 我撕了大部分设置后,Ember Data会急切地自行加载商店,并将使用灯具ID等而不指定它。 (这部分可以放回去,在这种情况下就没有必要了。) },(container, context) -> container.register 'store:main', DS.Store container.register 'adapter:application', DS.FixtureAdapter context.__setup_properties__.store = -> container.lookup('store:main')
- 我事先表示歉意,我不是coffeescript的粉丝,所以我全都放在js中。现在的问题是,如果您仍然遇到任何问题,我们可能需要找出您使用的Ember,ED和Ember Qunit版本。
