angularjs - Unit Test not giving expected error on grunt dev-test check -

i trying begin run unit tests while learning mean using grunt dev-test check following, should return error. however, in terminal grunt dev-test detects file being changed , reports no errors.

'use strict';  describe('appmydirective', function() {     var elm, elmscope, $scope, $compile, $timeout;  beforeeach(module('myapp'));  /** @param params     @param {string} html */ var createelm =function(params) {     var html ="<div app-my-directive>"+     "</div>";     if(params.html) {         html =params.html;     }     // elm =angular.element(html);     elm =$compile(html)($scope);     // $scope.$digest();     $scope.$apply();        //note: required otherwise alert directive won't compiled!!!! ... wtf?     elmscope =elm.isolatescope();     var elements ={         // 'somepart':elm.find('div').children().find('div')     };     return elements; };  beforeeach(inject(function(_$rootscope_, _$compile_, _$timeout_) {     $compile = _$compile_;     $timeout = _$timeout_;     $scope = _$rootscope_.$new(); }));  // aftereach(function() { // });   it('should have scopeone property', function() {     $scope.scopeone ='test scope one';     var html ="<div app-my-directive scope-one='scopeone'></div>";     createelm({html:html});     expect(elmscope).tobe('test scope one1');     }); }); 

since $scope.scopeone ='test scope one'; , expect 'test scope one1' should not pass 'untruthy'. or doing wrong here?

directive code:

please provide code directive have "expected undefined 'test scope one1'." - feel free execute tests "run code snippet"
