Interface ServiceOverrides

replaceSingleton

• replaceSingleton<T>(token: ServiceToken<T>, create: () => T): void

  Replaces (or adds) a singleton before the container is built. The replacement is used everywhere that exact token object is injected and never mutates the shared production plan.

  Use a fresh fake per host. A singleton may be retained until stop() and is disposed by the host if it implements the framework's disposable contract.

  Type Parameters

  • T

  Parameters

  • token: ServiceToken<T>
