What’s one way to programmatically query testimonials on a page without using shortcodes or widgets

<?php
$paged = get_query_var('paged') ? get_query_var('paged') : 1;
$args = array( 'paged' => $paged, 'posts_per_page' => 10, 'orderby' => DESC, 'post_type' => Testimonials_Widget::pt );
// The Query
query_posts( $args );
// The Loop
while ( have_posts() ) : the_post();
// do your thing…
endwhile;
?>
