New site subdomain testing

I created a test subdomain for testing my first WP site to show it to customer until it’s complete.

What files exactly do I have to put in the test directory?
The whole wp directory, the wp-content directory or what else?

I was also told that I have to adjust in the wp-config.php file the path to files in the test directory.

Considering that my path (as reported by provider) is \”/public/test\ what exact path do I have to put here:

/** Absolute path to the WordPress directory. */
if ( !defined(‘ABSPATH’) )
define(‘ABSPATH’, dirname(__FILE__) . ‘/’);

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . ‘wp-settings.php’);

Thanks
