is it possible to assert a Done event

[cobalt raft]

I want to assert a Done event, something like assertEvent(event, 'xstate.done.actor.save-record'), is this possible?

Yes, it's possible. You just need to explicitly define a DoneEvent in your types like so and then you can use in assertEvent.

import { type DoneActorEvent, setup } from 'xstate';


const machine = setup({
  types: {
    events: {} as {
      { type: 'event' } | 
      (DoneActorEvent<YourActorOutput> & { type: 'xstate.done.actor.actorID' })
    }
  }
}).createMachine()

We hope to automatically add done/error/snapshot actor events to the event typings automatically too; just haven't done this yet

Thanks for the reply, I’ll try typing the event as suggested for now, thanks.

This feature would be great! I keep forgetting to add the types to the types setup
