Karma + Angular undefined error

I just started angular testing with karma and jasmine. I've written two basic tests. One of the two tests pass, but the other one is failing. I can't seem to debug it. I've been looking everywhere, and it should work according to various tutorials. The $scope variable should be available. I get the following error (and a lot of text, see ):

The two tests are as following. The first one passes and the other one gives the above undefined error.

The one that passes:

describe('Testing MEAN Main Module', function() {
    var mainModule;
    beforeEach(function() {
        mainModule = angular.module('mean');
    });
    it('Should be registered', function() {
        expect(mainModule).toBeDefined();
        console.log('Success!');
    });
});

The one that fails:

describe('Testing the Shared Stats controller', function(){
    var SharedController,$scope;

    beforeEach(function(){
        // load the module you're testing.
        module('mean');

        inject(function($rootScope,$controller){
            // create a scope object for us to use.
            $scope = $rootScope.$new();

            SharedController = $controller('shared.StatsController',{
                $scope:$scope
            });
        });
    });
    it('Should contain a user object',function(){
        // User cannot be undefined
        expect($scope.test).toEqual('yoo');
    });

});

The angular controller is looking like this:

// Create the 'shared' controller
angular.module('shared').controller('shared.StatsController', [ '$scope',
    function($scope) {
        $scope.test = 'yoo';
    }
]);

Angular version is 1.4 and the karma dependencies are versions:

"karma": "~0.12.23",
"karma-jasmine": "~0.2.2",
"karma-phantomjs-launcher": "~0.1.4",

I have been breaking my neck over this all day. I hope someone with more knowledge about testing angular can help me out.
