Angular unit testing: how to test controller properties without scope

I'm trying to write some tests for a controller, but ALL the documentation/tutorials/etc on this demonstrate with functions and variables on $scope. What if you want to test something NOT on $scope?

Ex:

app.controller('fakeCtrl', function($scope) {

    var foo = 'bar';

    function fooBar() {
        console.log('foo bar');
    }

});

Is there any way to unit test foo or fooBar()?

Here's what DOESN'T work:

describe("fake controller", function(){

    beforeEach(module('app'));

    var $controller;

    beforeEach(inject(function(_$controller_, $rootScope){
        $controller = _$controller_;
        $scope = $rootScope.$new();
    }));

    describe('foo property', function() {
        it('is bar', function() {
          var controller = $controller('fakeCtrl', { $scope: $scope });
          expect(controller.foo).toEqual('bar');
        });
    });
   ...
