**1-** Generate a Custom Page Template called:Test Page and loaded by following code<br />
**2-** Generate a Page Called TestPage based on Test Page Template

    <?php
    /*
    Template Name: Test Page
    */
    ?>
    <?php get_header(); ?>
    
    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
        <h1><?php the_title() ;?></h1>  
        <?php the_content(); ?>
    <?php endwhile; else: ?>
        <p>Sorry, this page does not exist</p>
    <?php endif; ?>
    
    <?php get_footer(); ?>
