Sinon + Backbone spec che non funziona con Jasmine Headless Webkit ma passa con Jasmine standalone

Question

Ho una specifica di raccolta Backbone (che ovviamente utilizza anche Sinon per falsificare la risposta del server con i dati delle fixture. Questo passa con Jasmine standalone, ma fallisce sotto il mio setup di Jasmine Headless Webkit.

Il fallimento è questo:

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 e la mia gara di ritorno correttamente un reposonse falso con 2 todos, ma nessun todos vengono analizzati nella collezione.

C'è un violino che mostra tutto questo lavoro con Jasmine standalone here

mio ordine di caricamento Jasmine Headless Webkit è il seguente:

E il codice (anche il violino, ovviamente):

    model: window.Todo 
    url: "/todos" 
    comparator: (todo) ->

    res.response.todos

    @fixtures = Todos: 
    valid:

     response: 
     todos: [ 
      id: 1 
      title: "Paint the fence" 
     , 
      id: 2 
      title: "Wash the dog" 
     ] 


# spec/javascripts/helpers/valid_response.js.coffee 
beforeEach -> 
    @validResponse = (responseText) -> 
    [ 200, "Content-Type": "application/json", 
     JSON.stringify responseText ] 


# abbreviated todo spec (full spec in fiddle) 
describe "Todos collection", -> 

    describe "when fetching models from the server", -> 
    beforeEach -> 
     @todo = sinon.stub(window, "Todo") 
     @todos = new Todos() 
     @fixture = @fixtures.Todos.valid 
     @server = sinon.fakeServer.create() 
     @server.respondWith "GET", "/todos", @validResponse(@fixture) 

    afterEach -> 
     @server.restore() 
     @todo.restore() 

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

Diversi degli strumenti in uso sono nuovi per me quindi apprezzo davvero qualsiasi aiuto-- grazie !!

Forse c'è qualcosa di asincrono in server.respond(). Hai provato questo?

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
