Sinon + Backbone仕様はJasmine Headless Webkitでは失敗しましたが、スタンドアロンのJasmineを使用しています

Question

私はSinonを使用してFixtureデータでサーバーの応答を偽装するBackboneコレクション仕様（もちろん）を持っています。これはスタンドアロンのJasmineと一緒に過ぎますが、Jasmine Headless Webkitの設定では失敗します。

失敗はこれです：

Todos collection when fetching models from the server should parse todos from the response. 

    Expected 0 to equal 2. (line ~58) 
    expect(this.todos.length).toEqual(this.fixture.response.todos.length); 

Sinonと私の固定具は、適切に2つのドスと偽reposonseを返しますが、何のドスをコレクションに解析されていません。

ジャスミンと協力し、このすべてを示すフィドルがあり、スタンドアロンhere

次のように私のジャスミンヘッドレスWebkitのロード順序は次のとおりです。

     @todos = new Todos() 
     @fixture = @fixtures.Todos.valid 
     @server = sinon.fakeServer.create() 
     @server.respondWith "GET", "/todos", @validResponse(@fixture) 

    afterEach ->

     @todo.restore() 

    it "should parse todos from the response", ->

     @server.respond() 
     expect(@todos.length).toEqual @fixture.response.todos.length 
     expect(@todos.get(1).get('title')).toEqual @fixture.response.todos[0].title 

使用されているツールのいくつかは私にとっては新しく、本当に助けていただきありがとうございます。

Answer 1

server.respond()に何らかの非同期が発生している可能性があります。 これは試しましたか？

it "should parse todos from the response", -> 
    @todos.fetch() 
    @server.respond() 
    waits 500 
    runs -> 
    expect(@todos.length).toEqual @fixture.response.todos.length 
    expect(@todos.get(1).get('title')).toEqual @fixture.response.todos[0].title
