Unit testing window.onerror with jasmine

I am new to javascript and trying to use jasmine to unit test some error handling code.

In particular, I am trying to write several tests that confirm that our custom code (called windowHandleError), which replaces window.onerror (), is called and does what we want.

I tried something like:

       it("testing window.onerror", function() {
        spyOn(globalerror, 'windowHandleError');
        globalerror.install();

        var someFunction = function() {
            undefinedFunction();
        };
        expect(function() {someFunction();}).toThrow();
        expect(globalerror.windowHandleError).toHaveBeenCalled();
    });

But this does not cause attacks. There are some related questions that I have been looking at, but they seem to be asking about specific browsers or how / where to use onerror instead of testing it.
window.onerror does not start in Firefox
