How to test controller created via module.config in angularjs -

i have controller defined in following manner, works perfect. when try test controller says "(controller name)" not function, got undefined". how can test controller defined way.

controller.js

var mainmodule = angular.module('module1');  function home($scope) {     $scope.test = "hello"; } home.$inject = ["$scope"];  mainmodule.config(['$routeprovider',     function ($routeprovider) {         $routeprovider.when('/', {             templateurl: 'partials/home.html',             controller: home         });     } ]); 

testspec.js

describe("test home controller", function () {   beforeeach(module('module1'));     it("test controller ", inject(function ($rootscope, $controller) {         var ctrl = $controller("home", {             $scope: $rootscope         });         expect($rootscope.items.length).tobe(3);     })); }); 

as mentioned in comments @paolomoretti, shouldn't define controller in global scope (unless prototyping). instead definie controller part of module:

var mainmodule = angular.module('module1');  mainmodule.controller('home', function($scope) {      $scope.test = "hello"; }); 

then, when use line in test:

beforeeach(module('module1')); 

the controller available testing.
