如何断言使用茉莉花点击事件调用间谍?

I'm writing a simple click handler and need the event passed in (like so)

Thing = function($){

    var MyObject = function(opts){
        this.opts = opts;
    };

    MyObject.prototype.createSomething = function(){
        var that = this;
        $('#some_dom_element').live('click', function(e) {
            that.doStuff(e);
        });
    };

    MyObject.prototype.doStuff = function(e) {
        //do some javascript stuff ...
        e.preventDefault();
    };

    return MyObject;

}(jQuery);

目前在我的 jasmine 规范中，我有一些东西可以监视我期望被调用的函数(但是因为它是用 e 调用的——不是没有 args——我的断言失败了)

    it ("live click handler added to the dom element", function(){
        var doSpy = spyOn(sut, 'doStuff');
        sut.createSomething();
        $("#some_dom_element").trigger('click');
        expect(doSpy).toHaveBeenCalledWith();
    });

    it ("should prevent default on click", function(){
        var event = {
            type: 'click',
            preventDefault: function () {}
        };
        var preventDefaultSpy = spyOn(event, 'preventDefault');
        sut.createSomething();
        $("#some_dom_element").trigger(event);
        expect(preventDefaultSpy).toHaveBeenCalledWith();
    });

var event = {
    type: 'click',
    stopPropagation: function(){}
}
var spy = spyOn(event, 'stopPropagation');
$('#some_dom_element').trigger(event);
expect(spy).toHaveBeenCalled();
