Hello,

I am trying to used the new Typed ActorTestKit with a custom ActorSystemSetup. In the untyped TestKit, it was easy because you could provide the actor system in the constructor:

> <https://github.com/akka/akka/blob/3bc627ad42488730e065f497b992c9700ef2141d/akka-testkit/src/main/scala/akka/testkit/TestKit.scala#L928>

But with the typed ActorTestKit you can only specify custom config settings:

> <https://github.com/akka/akka/blob/3bc627ad42488730e065f497b992c9700ef2141d/akka-actor-testkit-typed/src/main/scala/akka/actor/testkit/typed/scaladsl/ActorTestKit.scala#L73>

For reference, I am trying to use Typed actors along side Lagom Persistent Entites, and it requires you to provide a serializer for each class on actor system setup (See here: [https://www.lagomframework.com/documentation/1.5.x/scala/PersistentEntity.html#Unit-Testing](https://www.lagomframework.com/documentation/1.5.x/scala/PersistentEntity.html#Unit-Testing)).

How would I go about testing typed actor and persistent entity interactions?

Regards,

- Robert

Looks like that would require some changes and an additional factory method, please create an issue about it!
