name: TestService
type: class
memory_category: Instances
summary: |
  A service used by Roblox to run controlled tests of the engine. It is
  available for developers to use, to a limited degree.
description: |
  `TestService` is a service used by Roblox internally to run analytical tests
  on the engine.

  Scripts that are executed inside of `TestService` (via
  `Class.TestService:RunAsync()`) have access to special macros that directly
  invoke functions under the service. Macros are essentially substitutions for
  large blocks of code that shouldn't need to be rewritten each time you want to
  call them.

  #### RBX_CHECK

  This macro does tests with calls to the `Class.TestService:Check()` function.

      Note that if the `Class.TestService.NumberOfPlayers|NumberOfPlayers`
      property is set to a value above `0`, running the game will open
      `NumberOfPlayers + 1` Studio windows where one window is a server and the
      rest are players connected to that server. Try to keep this value within a
      rational range (1 to 8 players) or else your computer's CPU will get
      overloaded.
