        describe( ‘Forgot Password: with username‘, ()=> {
            let dirElementInput;
            beforeEach( ()=> {
                // Find the input control:
                dirElementInput = directiveElem.find(‘input‘);

                // Set some text!
                angular.element(dirElementInput).val(‘[email protected]‘).trigger(‘input‘);
                $scope.$apply();
            } );

            it( ‘should have username‘, ()=> {
                expect(directiveCtrl.user.username ).toEqual([email protected]);
            } );

            it(‘should call UserService\‘s forgotPassword function‘, ()=>{

                spyOn(UserService, ‘forgotPassword‘);
                angular.element( directiveElem.find( ‘button‘ )[ 2 ] )
                       .click();
                expect(UserService.forgotPassword).toHaveBeenCalled();
            });
        } );

        describe(‘Forgot password: without username‘, ()=>{
            let dirElementInput;
             beforeEach( ()=> {
                 dirElementInput = directiveElem.find(‘input‘);
                 angular.element(dirElementInput).val(‘‘).trigger(‘input‘);
                 $scope.$apply();
             });

            it(‘should have empty username value‘, ()=>{
                expect(directiveCtrl.user.username).toBeUndefined();
            });

            it(‘should not call UserService\‘s ForgotPassword function‘, ()=>{

                spyOn(UserService, ‘forgotPassword‘);
                angular.element( directiveElem.find( ‘button‘ )[ 2 ] )
                       .click();
                expect(UserService.forgotPassword).not.toHaveBeenCalled();
            })
