How to test ajax error callback?

Within an ajax request how can the error callback be tested ? Is it possible to simulate a network connection error ?

    $.ajax({
        url: "myUrl",       
        type: 'post',
        dataType : "json",
        data : ({
            myJson
        }),
        success : function(jsonSaveResponse) {  

        },
        error: function (xhr) {

    } 

    });

If your URL is a PHP page, you can do something like this:

<?php
    header("HTTP/1.0 404 Not Found");
    exit();
    //the rest of your code

You can simply comment it out later when you're done testing your error function.

You could simply put an incorrect URL into the URL attribute of the AJAX call.

You have to stub the ajax request, and return a custom response that will trigger the error callback. You can do this easily with Javascript testing frameworks such as Jasmine.

What I do is just turn my server off before I make the AJAX request, which will simulate the server not responding.

Remember it'll need to be switched back on before you can refresh for changes.
