Error Karma 'undefined' scope variable in beforeEach

Here are my 2 files and error. I am running Karma, here is my karma.conf.js: https://gist.github.com/devanp92/a87c0bcc2bf5b8e17f64. After running 'karma start' I get this error. It is a very simple test file (or so I assume) and I am still getting these errors.

Main.js - This is a controller

angular.module('SSLApp').controller('MainCtrl',  
  function($scope, $rootScope) {
    $scope.thing = 1;
});

MainSpec.js - This is my test file

describe('MainCtrl', function() {
var controller, scope;

beforeEach(angular.module('SSLApp'));

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

it('should have scope to be defined', function(scope) {
    expect(scope).toBeDefined();
});

});

ERROR! It looks like it is being called undefined in the var MainCtrl = $controller...

You have two mistakes in your test code.

First of all you use wrong module function. The angular.module() function provides a real framework module while simple module() is an alias for angular.mock.module() which you should use in tests. So you ought to write your beforeEach function as follows:

beforeEach(module('SSLApp'));

Besides, you defined the test case function with a parameter but it should be parameterless. The scope variable is accessible from the outer scope. 

it('should have scope to be defined', function() {
    expect(scope).toBeDefined();
});
