Checking if category has posts

Hi,

I would like to do such thing :

I’ve got a table which displays posts from category ‘test’. Posts are displayed using standard

<?php query_posts('category_name=test&amp;showposts=3'); ?>
 <?php while (have_posts()) : the_post(); ?>

But i’d like to add another loop above this loop (and above the wrapper that this loop is inside of) so it would check if the category ‘test’ has posts – if so go and do the loop mentioned above, if not – display nothing. Or maybe there is another way to hide a theme module ?
