ember-konacha-rails isValid AssertionError

Question

我正在使用 Ember-konacha-rails 测试我的 ember.js 应用程序，

这是我正在测试的模型：

//sales_rep.js

App.SalesRep = DS.Model.extend({
firstName: DS.attr('string'),
lastName: DS.attr('string'),
});

这是测试：

 #= require spec_helper

describe "App.SalesRep", ->
  beforeEach( ->
    Test.store = TestUtil.lookupStore()
  )

  it "is a DS.Model", ->
    assert.ok App.SalesRep
    assert.ok DS.Model.detect(App.SalesRep)

  describe "attribute: firstName", ->
    it "can be created with valid value", ->
      Ember.run( ->
        Test.contact = App.SalesRep.createRecord firstName: 'Joe'
      )
      expect(Test.contact.get 'firstName').to.equal 'Joe'




    describe "attribute: lastName", ->
        it "can be created with valid value", ->
          Ember.run( ->
            Test.contact = App.SalesRep.createRecord lastName: 'swanson'
          )
          expect(Test.contact.get 'lastName').to.equal 'swanson'


        it "can NOT be created with invalid value", ->
          Ember.run( ->
            Test.contact = App.SalesRep.createRecord firstName: '123'
          )
          expect(Test.contact.get 'firstName').to.not.equal 'Joe'
          expect(Test.contact.isValid).to.be.equal false

属性测试通过，但expect(Test.contact.isValid).to.be.equal false 失败 这是错误：

    can NOT be created with invalid value ‣

因此我一般是 JS 新手，我不知道如何解决这个问题？ 是测试语法错误吗？

或者我应该向 Ember 模型添加验证吗？

Answer 1

尝试：

expect(Test.contact.get('isValid')).to.be.equal false

基本上加上.get('isValid')
