Gulp test can not find module

I generated my web application with [gulp angular][1]. Then I created a service and want to test it.

Module file is app.module.js

angular.module('text', []);

Service file is text.service.js

(function () {
  'use strict';
  angular.module('text')
    .factory('description',TextService);

  TextService.$inject = ['$http']

  function TextService($http) {

    return {
      QueryStaticText: queryStaticText

  };

    function queryStaticText(link) {
      return link;
    }
  }

})();

Test file is text.service.spec.js

'use strict';

describe('TextService', function () {
  var description;

  beforeEach(function () {

    module('text');

    inject(function (_description_) {
      description = _description_;
    });

  });

  it('should return text', function () {
    expect(description.QueryStaticText("Hello")).toEqual("Hello anu");
  });
});

In the console I execute gulp test and I've got the error message

The text module is not loaded, how can I load it?
