ember-cli: ember test error global modules not found

Using ember-cli 0.1.15 'ember test' giving error trying to use moment. The helper below loads fine in the browser, but the test fails trying to find moment.js:

Could not find module app/helpers/bower_components/moment/moment

App Helper

import Ember from 'ember';
import moment from './bower_components/moment/moment';
export function formattedDate(date, format) {
  return moment(date).format(format);
}
export default Ember.Handlebars.makeBoundHelper(formattedDate);

Test

import {
  formattedDate
} from '../../../helpers/formatted-date';
import { module, test } from 'qunit';

module('FormattedDateHelper');

test('Unit FormattedDate', function(assert) {
  var Xmas95 = new Date('December 25, 1995 11:15:30');
  var result = formattedDate(Xmas95,'MMMM Do, YYYY [at] h:mm a');
  assert.ok(result === 'December 25th, 1995 at 11:15 am', 'boom:  '.concat(result));
});

Brocfile.js

var EmberApp = require('ember-cli/lib/broccoli/ember-app');

var app = new EmberApp();

app.import('bower_components/moment/min/moment.min.js');
module.exports = app.toTree();
