Preparation code

Preparation code HTML (this will be inserted in the <body> of a valid HTML5 document in standards mode) (useful when testing DOM operations or including libraries)

function mySandwich(param1, param2, callback) {  
    console.log('Started eating my sandwich.\n\nIt has: ' + param1 + ', ' + param2);  
    var sth = "test";
    callback(sth);  
}

// Non nested function inner function

function mycallback(sth) {
      console.log('Finished eating my sandwich.' + sth);

}

// YUI style (http://www.yuiblog.com/blog/2007/06/12/module-pattern/)
var myNamespace = myNamespace || {};
myNamespace.module1 = (function() {
         
    //"private" method:
    var getNextAge3 = function(age) {
        return age + 1;
    }          
      
    return {
        person3: function(age) {
            return getNextAge3(age);
        }
    };
}());

// Adding New Functionality to the person4
// http://enterprisejquery.com/2010/10/how-good-c-habits-can-encourage-bad-javascript-habits-part-1/
(function( person4, $, undefined ) {
		    
    person4.Age = 0;
		    		
    //Public Method
    person4.getNextAge = function() {
        return person4.Age + 1;
    };    
}( window.person4 = window.person4 || {}, {} ));

</script>

Include JavaScript libraries as follows: <script src="//cdn.ext/library.js"></script>

Define setup for all tests (variables, functions, arrays or other objects that will be used in the tests) (runs before each clocked test loop, outside of the timed code region) (e.g. define local test variables, reset global variables, clear canvas, etc.) (see FAQ)

Define teardown for all tests (runs after each clocked test loop, outside of the timed code region) (see FAQ)
