How do you get a reference to an angularjs controller defined in a module?

I have a jasmine test and I can't get a reference to the controller constructor function as it was defined in a module. See my gist here https://gist.github.com/hcabnettek/5222429

I need to unit test a controller defined like

angular.module('foo', []).controller('fooCtrl', function($scope){ $scope.foo = 'bar'; });

Can anyone possibly help me out? Thanks!
