What's the story of ActorTestKit?

ActorTestKit seems to not create an untyped system, so I run into issues when adapting the typed system to an untyped, e.g. for Http() or such.

Are you planing to change ActorTestKit such that it is based upon an untyped system? Or should there be another trait for that purpose?

That must be something else, it’s an untyped ActorSystem underneath.

I was thinking it could be https://github.com/akka/akka-http/issues/1873 but that is fixed in 10.1.0. Can you share error message and stack trace?

Ah, yes. Was using BehaviorTestKit. Sorry for the confusion.
