How to implement template file and the loop

Question

I am trying to understand how to use a custom template file, in this case simply to list all posts. Based on my research, and initial responses to this post, the code looks like this:

 <?php
 /**
 * Template Name: Basic Test
 */
 get_header();
 
 if ( have_posts() ) : 
     while ( have_posts() ) : the_content();
        the_title();
     endwhile;
 else :
     _e( 'Sorry, no posts matched your criteria.', 'textdomain' );
 endif;

 get_sidebar();
 get_footer();
 ?>

When I create a new page that uses this template file, the page displays the header, footer, sidebar, page title, and nothing else. I assume I am missing something, but I don't know what. Neither posts nor the error message are displayed.

I have seen that there is extra (); so maybe this syntax error prevent display in front-end please try below code -

<?php
/**
* Template Name: Basic Test
*/
get_header();

if ( have_posts() ) : 
    while ( have_posts() ) : the_post();
       the_title();
    endwhile;
else :
    _e( 'Sorry, no posts matched your criteria.', 'textdomain' );
endif;

get_sidebar();
get_footer();
?>
