unit testing angular service call using jasmine.js

i have tried a service call using angular.js and it is working perfectly i am trying to unit test it using jasmine.js but i have come across some errors eventhough i tried so many different methods these errors cannot be recovered

describe('Myctrl', function() {

   var $httpBackend, scope, createController, authRequestHandler;

   // Set up the module  
   beforeEach(module('myApp'));

      alert("Hello there!");

    beforeEach(inject(function ($injector) {
     // Set up the mock http service responses
        alert("Hello there!");
    $httpBackend = $injector.get('$httpBackend');

     // backend definition common for all tests
    alert("Hello there!");
     authRequestHandler = $httpBackend.whenGET('GET', 'http://ift.tt/1aaNO8P')
                            .respond(true);

     // Get hold of a scope (i.e. the root scope)

     $rootScope = $injector.get('$rootScope'); 

     // The $controller service is used to create instances of controllers
     var $controller = $injector.get('$controller');


     createController = function() {

       return $controller('Myctrl', {'$scope' : scope});

     };

   })



);
/*
  afterEach(function () {
    $httpBackend.verifyNoOutstandingExpectation();
    $httpBackend.verifyNoOutstandingRequest();
  });
*/


  it('should fetch authentication token', function() {
       //create expectation   
     $httpBackend.expectGET('GET','http://ift.tt/1aaNO8P')
     var controller = createController()
     $httpBackend.flush();
     expect(scope.names).toBeTruthy(true); 

   });


});

what would be the solution for the error ?
