Not sure what you are trying to do. You could force an error at that line but there is a chance it would never run. Do you want the exception if the folder already exists? Or do you want the execption if the script is unable to create the folder?

You could do something like this

function folderAdd(newName){
    var res;
    var myFolder = new Folder(newName);
    if(myFolder.exists) res = 'Folder already exists';
    if(!myFolder.create()) res = 'Unable to create folder';
    return res;
}
function showError(e){alert(e)};
try{
    var newName = 'test';
    var err = folderAdd(newName);
    if(undefined != err) throw(err);
}
catch(e) {
 showError(e);
}
