Displaying posts on homepage – Template Page

The template tags (like the_content()) aren’t available when using get_posts. In order to make the template tags available, you have to make use of setup_postdata( $post );

Example:

<?php 
$posts = get_posts('category_name=category-test'); 
foreach($posts as $post) { 
    setup_postdata( $post );

    the_title(); ?>
    <p><?php the_content(); ?></p>
<?php } ?>
