Answer 1

The problem is that you call $.test before you defined it. Call it after the definition:

$(document).ready(function(){

    $.test =    function(){
        alert('HELLO WORLD');
    }

    $.test();
});

Simply do this:

$(document).ready(function(){

    $.test =    function(){
        alert('HELLO WORLD');
    }
})();

Call the function after you define it, not before.

Or:

$(document).ready(function(){

            $.test =    function(){
                alert('HELLO WORLD');
            }
      $.test();
        });
