The 'MyClass' objects that your trying to initialize, do you have control
over the interface? From my perspective if you look at this from another
angle all your problems go away. Instead of having your 'MyClass' accept
multiple parameters, why not take a parameter object. Extend your class with
'Options' in this fashion you could put your default values in and not worry
about testing. In addition you don't need to worry about parameter order.
function initObj(params){
var o = new MyClass(params);
}
MyClass = new Class({
Implements : [Options],
options : {
'default1' : 'value1',
'default2' : 'value2
},
initialize : function(params){
this.setOptions(params);
}
});
