Add params to Ember Data's RESTAdapter AJAX requests.
App.accountId = 'asdf';
App.RESTAdapter = DS.RESTAdapter.extend({
// Scope all ajax calls.
ajax: function(url, type, hash) {
if (Ember.isEmpty(hash)) hash = {};
if (Ember.isEmpty(hash.data)) hash.data = {};
hash.data.account_id = App.accountId;
this._super(url, type, hash);

// choose an option
find(selector).val(value);
// trigger the change
find(selector).change();
// assert the selected option
equal(find(selector+" option:selected").val(), value, description||"makes the selection");
