How to properly unit test Angular directive

I'm attempting to test an Angular directive, but keep running into the following error:

Error: Unexpected request: GET /api/players/info

I believe this is because of references to my controller within my directive definition object, but I'm not sure how to handle it. Below is my directive, then my test:

playerInfo.directive.js:

'use strict';

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

function playerInfo() {
  var directive = {
    link: link,
    restrict: 'E',
    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'});
    });
  }
}

playerInfoSpec.js:

'use strict';

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

  beforeEach(module('gameApp'));

  beforeEach(inject(function($templateCache) {
    var templateUrl = '/app/player/playerInfo.directive.html';
    var asynchronous = false;
    var req = new XMLHttpRequest();
    req.onload = function() {
      $templateCache.put(templateUrl, this.responseText);
    };
    req.open('get', '/base' + templateUrl, asynchronous);
    req.send();
  }));

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

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

My controller uses an injected service to send a GET request to /api/players/info which is why I believe this error has something to do with my controller reference in my directive definition object.
