AngularJS test, can't find my controller

I met a problem with testing my controllers. I load them dynamically (lazy load, see after) so I wrote them like this :

angular.module('myApp').controllerProvider.register('DashboardCtrl', [
    '$scope', function ($scope) {
        $scope.foo = 'bar';
    }
]);

I initialise my module like this :

var app = angular.module('myApp', [
    'ngRoute',
    'ngCookies',
    'ngResource',
    'ngSanitize',
    'ui.router'
]);

app.run([
    '$rootScope', '$state', '$stateParams',
    function ($rootScope, $state, $stateParams) {
        $rootScope.$state = $state;
        $rootScope.$stateParams = $stateParams;
    }
]);

app.config(function ($stateProvider, $urlRouterProvider, $controllerProvider, $compileProvider, $filterProvider, $provide) {
    app.stateProvider = $stateProvider;
    app.routeProvider = $urlRouterProvider;
    app.controllerProvider = $controllerProvider;
    app.compileProvider = $compileProvider;
    app.filterProvider = $filterProvider;
    app.provide = $provide;

    $urlRouterProvider.otherwise('/');

    $stateProvider
        .state('dashboard', {
            url         : '/',
            templateUrl : 'views/dashboard.html',
            controller  : 'DashboardCtrl',
            resolve     : {
                deps : function ($q, $rootScope) {
                    var deferred = $q.defer();

                    curl('scripts/controllers/dashboard.js')
                        .then(function () {
                            $rootScope.$apply(function () {
                                deferred.resolve({});
                            });
                        });

                    return deferred.promise;
                }
            }
        });
});

That works. Method is described there : http://ify.io/lazy-loading-in-angularjs/

But when I want to test, I get each time the error : Error: [ng:areq] Argument 'DashboardCtrl' is not a function, got undefined

My test script :

describe('Controller: DashboardCtrl', function () {
    'use strict';

    var DashboardCtrl,
        scope;

    // load the controller's module
    beforeEach(function () {
        var app = angular.module('cellierApp', [
            'ngRoute',
            'ngCookies',
            'ngResource',
            'ngSanitize',
            'ui.router'
        ]);

        app.run([
            '$rootScope', '$state', '$stateParams',
            function ($rootScope, $state, $stateParams) {
                $rootScope.$state = $state;
                $rootScope.$stateParams = $stateParams;
            }
        ]);

        app.config(function ($stateProvider, $urlRouterProvider, $controllerProvider, $compileProvider, $filterProvider, $provide) {
            app.stateProvider = $stateProvider;
            app.routeProvider = $urlRouterProvider;
            app.controllerProvider = $controllerProvider;
            app.compileProvider = $compileProvider;
            app.filterProvider = $filterProvider;
            app.provide = $provide;
        });

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

    it('should attach a list of awesomeThings to the scope', function () {
        expect(scope.foo).toBeDefined();
        expect(scope.foo).toBe('bar');
    });
});

I don't know what I'm doing wrong. Is there someone who knows ? Thanks in advance
