$scopeProvider <- $scope/ Unknown provider

问题

I testing my angular-application with jasmine(http://jasmine.github.io/2.0/) and getting next error: Unknown provider: $scopeProvider <- $scope I know, that it's incorrect to build dependency with scope in filters, services, factories, etc., but I use $scope in controller! Why am i getting this error? controller looks like

testModule.controller('TestCont', ['$filter', '$scope', function($filter, $scope){

        var doPrivateShit = function(){
            console.log(10);
        };

        this.lol = function(){
            doPrivateShit();
        };

        this.add = function(a, b){
            return a+b;
        };

        this.upper = function(a){
            return $filter('uppercase')(a);
        }   

        $scope.a = this.add(1,2);

        $scope.test = 10;

        $scope.search = {

        };
    }]);

and my test's code:

'use strict';

describe('testModule module', function(){
    beforeEach(function(){
        module('testModule');
    });

    it('should uppercase correctly', inject(function($controller){
        var testCont = $controller('TestCont');
        expect(testCont.upper('lol')).toEqual('LOL');
        expect(testCont.upper('jumpEr')).toEqual('JUMPER');
        expect(testCont.upper('123azaza')).toEqual('123AZAZA');
        expect(testCont.upper('111')).toEqual('111');
    }));
});

You need to manually pass in a $scope to your controller:

describe('testModule module', function() {
    beforeEach(module('testModule'));

    describe('test controller', function() {
        var scope, testCont;

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

        it('should uppercase correctly', function() {
            expect(testCont.upper('lol')).toEqual('LOL');
            expect(testCont.upper('jumpEr')).toEqual('JUMPER');
            ...
        });
    });
});

Normally, a $scope will be available as an injectable param only when the controller is attached to the DOM.

You need to associate somehow the controller to the DOM (I'm mot familiar with jasmine at all).

I am following a video tutorial from egghead (link bellow) which suggest this approach:

describe("hello world", function () {
    var appCtrl;
    beforeEach(module("app"))
    beforeEach(inject(function ($controller) {
        appCtrl = $controller("AppCtrl");
    }))

    describe("AppCtrl", function () {
        it("should have a message of hello", function () {
            expect(appCtrl.message).toBe("Hello")
        })
    })
})

Controller:

var app = angular.module("app", []);

app.controller("AppCtrl",  function () {
    this.message = "Hello";
});

I am posting it because in the answer selected we are creating a new scope. This means we cannot test the controller's scope vars, no?
