Managing dependencies for controllers during the testing of directives

Currently, I am conducting a test on an Angular directive using the spec provided below:

'use strict';

describe('playerInfo directive', function() {
  var element;
  var scope;

  beforeEach(module('gameApp'));
  beforeEach(module('templates'));

  beforeEach(inject(function($rootScope, $compile) {
    scope = $rootScope.$new();
    element = '<player-info></player-info>';
    element = $compile(element)(scope);
    scope.digest();
  }));

  it('should replace the element with the appropriate content', function() {
    expect(element.html()).toContain('Score:');
  });
});

Here is my directive code:

'use strict';

angular.module('gameApp')
  .directive('playerInfo', playerInfo);

function playerInfo() {
  var directive = {
    link: link,
    restrict: 'E',
    replace: true,
    templateUrl: '/app/player/playerInfo.directive.html',
    controller: 'PlayerInfoController',
    controllerAs: 'playerInfo'
  };
  return directive;

  function link(scope, element) {
    var address =  angular.element(element[0].getElementsByClassName('blur'));
    address.on('click', function() {
      address.css({'-webkit-filter': 'none'});
    });
  }
}

I keep encountering the error message

TypeError: 'undefined' is not an object (evaluating 'moment.utc')
.

UPDATE: It appears that the issue is not with my controller. The problem lies within my usage of the angular-moment directive twice in the HTML template of my directive:

<div>{{playerInfo.game.date | amDateFormat: 'MMMM Do, YYYY'}} - <b am-time-ago="playerInfo.game.date"></b></div>

This seems to be the cause of the error, but I am uncertain about how to resolve it. I have included both

src/assets/bower_components/moment/moment.js
and
src/assets/bower_components/angular-moment/angular-moment.js
in the files array of karma.config.js.

Answer №1

The issue arose from the sequence in which I specified essential files within the karma.config.js file. It is crucial that moment is defined prior to angular-moment:

files: [
  ...
  'src/assets/bower_components/moment/moment.js',
  'src/assets/bower_components/angular-moment/angular-moment.js',
  ...
],
