  14  * This class is solely used for being able to test Maintenance right now
  15  * without having to apply major refactorings to fix some design issues in
  16  * Maintenance.php. Before adding more functions here, please consider whether
  17  * this approach is correct, or a refactoring Maintenance to separate concers
  18  * is more appropriate.
  19  *
  20  * Upon refactoring, keep in mind that besides the maintenance scrits themselves
  21  * and tests right here, also at least Extension:Maintenance make use of
  22  * Maintenance.
  23  *
  24  * Due to a hack in Maintenance.php using register_shutdown_function, be sure to
  25  * finally call simulateShutdown on MaintenanceFixup instance before a test
  26  * ends.
