How to test directive loaded or not in angularjs

I have written directive which takes the directive name in parameter and load that directive dynamically as fallow:

.directive("loadDirective", function($compile, $timeout) {
        return {
            restrict: 'E',
            scope: {
                Dtype: '=type',
                subType: '@',
                data: "=data"
            },
            link: function(scope, element) {
                scope.$watch('Dtype', function() {
                    $timeout(function() {
                        var generatedTemplate = '<div ' + scope.Dtype + (scope.subType ? '-' + scope.subType + '-directive' : '-directive') + ' data="data" >dd</div>';
                        element.empty().append($compile(generatedTemplate)(scope));
                    })
                })
            },
        };
    })

here is my one of the directive which I will be loading it dynamically

.directive("dailyIntervalDirective", function() {
        return {
            scope: {
                data: '='
            },
            restrict: 'A',
            templateUrl: '/flat-ui/tpls/daily-interval.html'
        };
    })

now I am trying to write test case for the loadDiretive to test it load the directive or not as follow:

describe("loadDirective directive", function() {
    var elm, scope;
    beforeEach(module('guideApp.directives'));
    beforeEach(module('/flat-ui/tpls/daily-interval.html'));
    beforeEach(angular.mock.inject(function($rootScope, $compile) {
        scope = $rootScope;
        elm = angular.element('<load-directive type="directive" sub-type="interval" data="schedulerData"></load-directive>');
        compile = $compile;
        compile(elm)(scope);
        scope.schedulerData = {
            interval: 1,
        }
        scope.$digest();
    }));
    it("should be able to load daily directive", function() {
        scope.directive = "daily";
        var intervaldirective = elm.find('div[daily-interval-directive]');
        expect(intervaldirective.length).toEqual(1);
    });
   });

which is not working fine for me. I tried to log the elm but it not loading the dailyInterevalDirective.
