How to deal with controller dependencies when testing directives

I'm testing an Angular directive using the following spec:

'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:');
  });
});

and my directive:

'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'});
    });
  }
}

The error I keep seeing is TypeError: 'undefined' is not an object (evaluating 'moment.utc'). My controller utilizes moment in several places. How can I avoid this causing my tests to fail?
