How can I spy on a custom event in Jasmine?

[Indradhanush Gupta]

I am trying to spy on a custom event. But the problem I have is that it is failing when I am using spyOn to spy on that event. When I spy on some function it is working fine. Heres what I tried:

describe("Test:", function(){
    it("Expects event will be spied: ", function() {
        var eventSpy = spyOn(window, 'myEvent').andCallThrough();
        expect(eventSpy).toHaveBeenCalled();
        //Also tried this:
        //expect(eventSpy).not.toHaveBeenCalled();
    });
});

So I tried both not.toHaveBeenCalled() and toHaveBeenCalled() but it fails in both the cases. So I guess spyOn is unable to spy on the custom event. Is my approach wrong?

Have you tried to spy on the function triggered when the event is fired?

[David Linse]

don't you have to trigger the event..?

<code>

describe("Test:", function(){ it("Expects event will be spied: ", function() { var eventSpy = spyOn(window, 'myEvent').andCallThrough();

window.trigger('myEvent');

expect(eventSpy).toHaveBeenCalled();
</code>
