This Guidance helps developers test, visualize, and optimize their multiplayer games using the Amazon GameLift Testing Toolkit. With the toolkit, developers can troubleshoot, debug, and tune their Amazon GameLift infrastructure. This Guidance offers an optional capability to use virtual players that run the same code as real players so developers can test the success of their game before launching it into production.
