Codeigniter 4 extend core class process clarification

Thank you for your response, but the new session file / function still isn't being hit. Please see the changes made below and advise if you meant another way.

app/Libraries/Session.php is now just a clone of vendor/codeigniter4/framework/system/Session/Session.php - but with the namespace App\Libraries, and some debug added for testing (a var_dump in the get function, triggered by running vendor/bin/phpunit in the terminal, which calls get() via a unit test).

app/Config/Services.php now looks like the below (the forum code formatter appears broken on responses):

PHP Code:

namespace Config;

 use CodeIgniter\Config\BaseService;
 // use App\Libraries\Session;
 use Config\Session as SessionConfig;
 use Config\Services as AppServices;
 use CodeIgniter\Session\Handlers\DatabaseHandler;
 use CodeIgniter\Session\Handlers\Database\MySQLiHandler;
 use CodeIgniter\Session\Handlers\Database\PostgreHandler;

 class Services extends BaseService
 {
 public static function get($getShared = true)
 {
 if ($getShared) {
 return static::getSharedInstance('get');
 }

 $config ??= config(SessionConfig::class);

 $logger = AppServices::logger();

 $driverName = $config->driver;

 if ($driverName === DatabaseHandler::class) {
 $DBGroup = $config->DBGroup ?? config(Database::class)->defaultGroup;
 $db = Database::connect($DBGroup);

 $driver = $db->getPlatform();

 if ($driver === 'MySQLi') {
 $driverName = MySQLiHandler::class;
 } elseif ($driver === 'Postgre') {
 $driverName = PostgreHandler::class;
 }
 }

 $driver = new $driverName($config, AppServices::request()->getIPAddress());
 $driver->setLogger($logger);

 return new \App\Libraries\Session($driver, new SessionConfig());
 }
