Class MockProvider

constructor

• new MockProvider(): MockProvider

  Returns MockProvider

ReadonlyisReal

Readonlylabel

applyAction

• applyAction(instanceId: string, action: LifecycleAction): void

  Apply a lifecycle action decided by the engine, transitioning state.

  Parameters

  • instanceId: string
  • action: LifecycleAction

  Returns void

get

• get(nameOrId: string): Promise<ManagedInstance | null>

  Fetch a single instance by name or instance-id. Returns null if not found.

  Parameters

  • nameOrId: string

  Returns Promise<ManagedInstance | null>

hibernate

• hibernate(instanceId: string): Promise<void>

  Hibernate (RAM saved to disk).

  Parameters

  • instanceId: string

  Returns Promise<void>

launch

• launch(spec: LaunchSpec, launchTimeMs: number): Promise<ManagedInstance>

  Launch one instance from a spec at the given launch time (ms epoch).

  Parameters

  • spec: LaunchSpec
  • launchTimeMs: number

  Returns Promise<ManagedInstance>

list

• list(includeTerminated?: boolean): Promise<ManagedInstance[]>

  List all spawn-managed instances (spawn:managed=true), excluding terminated by default.

  Parameters

  • includeTerminated: boolean = false

  Returns Promise<ManagedInstance[]>

setTags

• setTags(instanceId: string, tags: Record<string, string>): Promise<void>

  Overwrite/merge tags on an instance. Used by extend to push out spawn:ttl-deadline, and by the sim to update spawn:compute-seconds.

  Parameters

  • instanceId: string
  • tags: Record<string, string>

  Returns Promise<void>

simTick

• simTick(
      nowMs: number,
      prevMs: number,
      opts?: { busy?: (i: ManagedInstance) => boolean },
  ): void

  Advance the simulated world to nowMs: accrue compute-seconds for running instances since their last-known point, and optionally mark them busy/idle. The UI's sim loop calls this, then runs the lifecycle engine over the result.

  Parameters

  • nowMs: number
  • prevMs: number
  • opts: { busy?: (i: ManagedInstance) => boolean } = {}

  Returns void

start

• start(instanceId: string): Promise<void>

  Start a stopped/hibernated instance.

  Parameters

  • instanceId: string

  Returns Promise<void>

stop

• stop(instanceId: string): Promise<void>

  Stop (billing pauses, EBS persists).

  Parameters

  • instanceId: string

  Returns Promise<void>

terminate

• terminate(instanceId: string): Promise<void>

  Terminate (permanent).

  Parameters

  • instanceId: string

  Returns Promise<void>
