I'm testing router and have two functions, and I need to test if first function was called and second was not. There is method toHaveBeenCalled but there is no method to test if function was not called. How can I test that?

I have code like this:

var args, controller, router;

beforeEach(function() {

    controller = {

        foo: function(name, id) {

            args = [].slice.call(arguments);

        },

        bar: function(name) {

        }

    };

    spyOn(controller, foo).and.callThrough();

    spyOn(controller, bar).and.callThrough();

    router = new route();

    router.match('/foo/bar/{{id}}--{{name}}', controller.foo);

    router.match('/foo/baz/{{id}}--{{name}}', controller.bar);

    router.exec('/foo/bar/10--hello');

});

it('foo route shuld be called', function() {

    expect(controller.foo).toHaveBeenCalled();

});

it('bar route shoud not be called', function() {

    // how to test if bar was not called?

});
