Bad Karma - trying to set up testing

I’m new to karma & jasmine, but I’ve successfully completed a few tutorials. However, I’m having trouble with my specific ionic setup and I know it has to do with my app ‘starter’ and my ‘starter.controllers’:

// app.js
// Ionic Starter App
// ...
// 'starter.controllers' is found in controllers.js
angular.module('starter', ['ionic', 'starter.controllers'])
.run(function($ionicPlatform, $http, $rootScope) {

// controllers.js
// ...
    .controller('AppCtrl', function ($scope) {
        $scope.hello = 'HELLO';
// ...

// AppCtrl-spec.js (test)
describe('Unit: AppCtrl', function() {
// Load the module with ContainerContactCtrl, add your module name in here!
    // beforeEach(module('starter.controllers')); // also tried this

    var ctrl, scope;

// inject the $controller and $rootScope services
// in the beforeEach block
    beforeEach(inject(function($controller, $rootScope) {

// create a new scope that's a child of the $rootScope
        scope = $rootScope.$new();

// create the controller
        ctrl = $controller('AppCtrl', {
            $scope: scope
    it('should do this and that',
    function() {
        expect(scope.hello).toEqual("HELLO"); // LINE 37: test run gives error that scope is undefined

BUT, I keep getting an error that “scope” is undefined on the line (37) above.
What am I missing?

Thank you,

I resolved this. I had some other JS files that I was not loading. Thank you.
