Using a mock to test the full fetch method, without a server

ajax-mock.spec.js

  describe('loads itself from the service', function () {
    beforeEach(function() {
     json = getJSONFixture('entities/Dataset/dataset.json');
      var response = {
          status: 200,
          responseText: JSON.stringify(json)
      };
      jasmine.Ajax.useMock();
      model = new Composer.Models.Dataset({id:json.data.id});
      model.fetch();
      var request = mostRecentAjaxRequest();
      request.response(response);

    });
    it('sets the version', function() {
      expect(model.get('current_version')).toEqual(json.data.current_version);
    });
    //lots more tests removed for brevity
  });
