There may be a simpler way, but this is how I'd do it:
for ( var i in test ) { alert( i ); }
Beware: the above will likely cause you to force-quit your browser if
test is a DOM node. After making that mistake three or four times, I
learned to write to the DOM instead of alerts when I'm debugging
objects.
Peace,
