Guide to writing a Jasmine test case to verify Toggle class behavior within a click event

My directive is responsible for toggling classes on an element, and it's working as expected. However, I seem to be encountering an issue with the jasmine test case for it.

// Code for toggling class
fileSearch.directive('toggleClass', function() {
   return {
     restrict: 'A',
     link: function(scope, element, attrs) {
        element.bind('click', function() {
            element.toggleClass(attrs.toggleClass);
        });
    }
};

});

Jasmine Test Case:

describe(
    'testing toggle-class directive',
    function() {
        var $compile, $rootScope;
        beforeEach(module('myApp'));

        beforeEach(inject(function(_$compile_, _$rootScope_) {
            $compile = _$compile_;
            $rootScope = _$rootScope_;
        }));

        it('should set highlight class on report title',
                function() {
                    var element = $compile("<div toggleclass='highlighted'</div>")($rootScope);
                    element.click();
                    expect(element).toHaveClass('highlighted');
                });

    });

I'm getting an error message stating that "undefined is not a constructor" at the line "expect(element).toHaveClass('highlighted');". Can anyone provide some guidance on this? I am relatively new to Angular.

CheckClass is not a feature of Jasmine. Perhaps consider using:

verify(element.attr('class')).equalsTo('highlighted');
