Reset to default 6The Sizzle() function returns an array of matched elements. So if you know there'll be exactly one matching element (which there should be if you're selecting by id) try:
alert(Sizzle("#test")[0].innerHTML);
You've did a slight mistake it returns NodeList not a single Node.
The NodeList is like an array but used for storing Nodes. You may probably want to use the first one.
// this is how you do it
alert( Sizzle('#test')[0].innerHTML );
