 At my work we work in strict mode where every error needs to be solved.
 Even undefined errors will fail the test platform.

 In wp-includes/load.php at line 369 it is assumed that DB_USER,
 DB_PASSWORD, DB_NAME and DB_HOST are defined as constants.

 When you don't have a config yet this is not the case.
 The solution would be muting the error or defining the constants as null.

 # Solution 1, prepend above the "new wpdb()":
     if (!defined('DB_USER')) {
         define('DB_USER', null);
     }
     if (!defined('DB_PASSWORD')) {
         define('DB_PASSWORD', null);
     }
     if (!defined('DB_NAME')) {
         define('DB_NAME', null);
     }
     if (!defined('DB_HOST')) {
         define('DB_HOST', null);
     }

 # Solution 2, modify the "new wpdb()" line:
 $wpdb = new wpdb( @DB_USER, @DB_PASSWORD, @DB_NAME, @DB_HOST );

 Where I would prefer to use solution 1.
