TypeError: scope is undefined Karma-jasmine-angular unit testing

I am new with karma-jasmine and trying to develop a demo test case. I am getting error of scope is not defined in 'it'. I have read the following links with same problem but it's not helping me with my test case.

Error Karma 'undefined' scope variable in beforeEach

TypeError: $scope is undefined in Angular controller unit test with Jasmine

This is my karma.conf.js

 module.exports = function(config) {
      config.set({

    exclude)
        basePath: '',


        frameworks: ['jasmine'],

     files: [
          'js/angular.js',
          'js/angular-mocks.js',
          'app.js',
          'test/**/*Spec.js'
        ],
        exclude: [
        ],

        preprocessors: {
        },
        reporters: ['progress'],
        port: 9876,

        colors: true,

    config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
        logLevel: config.LOG_INFO,

        autoWatch: false,


        browsers: ['Firefox'],

        singleRun: false 
      });
    };

Here is my mySpec.js where test code is written

describe('myApp', function() {

    beforeEach(module('myApp'));

    describe('HelloWorldController', function() {

        var scope,HelloWorldController;

        beforeEach(inject(function ($rootScope, $controller) {
            scope = $rootScope.$new();
            HelloWorldController = $controller('HelloWorldController', {
                $scope: scope
            });
        }));

        it('should assign message to hello world', function () {
            expect(scope.greeting).toEqual('Hello World!');
        });
    });
});

And this is my app.js where controller is defined.

var myApp = angular.module('myApp',[]);
myApp.controller('HelloWorldController', ['$scope', function($scope) {
    $scope.greeting = 'Hello World!';
}]);

The error which I get is,

TypeError: scope is undefined in** /home/abc/WebstormProjects/test1/test/basic/mySpec.js (line 17)

I don't have any idea of where I am making mistake. Please guide me toward this issue.

Thanks in advance.

One of your problems here was a typo. 'scope' was undefined, because in your controller injection, you defined it as '$scope', but your expect statement referenced 'scope':

describe('myApp', function() {

    beforeEach(module('myApp'));

    describe('HelloWorldController', function() {

        var scope,HelloWorldController;

        beforeEach(inject(function ($rootScope, $controller) {
            scope = $rootScope.$new();
            HelloWorldController = $controller('HelloWorldController', {
                $scope: scope
            });
        }));

        it('should assign message to hello world', function () {
            expect(scope.greeting).toEqual('Hello World!');
        });
    });
});
