For SO question: http://stackoverflow.com/questions/35035924/how-to-do-unit-testing-using-jasmine-on-that-factory

app.js

angular.module('behaviour', [])
  .factory('behaviours', behavioursFactory)
;

behavioursFactory.$inject = ['$http'];
function behavioursFactory($http) {
  var behaviours;
  
  $http.get('data.json').then(function(res) {
    behaviours = res.data;
  }, function(err) {
    /* hanlde http error */
  });
  
  return {
    get: function(name) {
      if (!behaviours) {
        /* http request failed or is still in progress */
      } else if (behaviours[name]) {
        /* behaviour exists, do something */
      } else {
        /* no behaviour with given name */
      }
    }
  };
}

it tells me that behaviours[name] is not an object and it's undefined ?
