The Test Server is a secondary server used to test new things before they become implemented in the main server. Players can log on with their regular login password.
Players can give themselves any items in the game in any quantity, and can remove items by adding a negative quantity even if it would give them a negative amount in their inventories. Any items in the players' inventories are retained from the main server, but garages and warehouses are emptied. Players have the same level and experience as on the main server.
The server gets reset every week to a copy of the main server.
