使用Context.DI（）的Akka.net测试演员

Question

I think this should be an "easy" one. I'm trying to test the behavior of an actor that performs a child actor creation when receiving a message. I'm using Context.DI().Props<ChildActor>() to create it and that's fine however there is an exception being thrown when I try to run the tests:

Cause: System.NullReferenceException: Object reference not set to an instance of an object.
   at Akka.DI.Core.DIActorContextAdapter.Props[TActor]()

And I have installed the Akka.TestKit, the Akka.DI.TestKit, etc. Is there anything I need to configure/set in my test to "mock" the Context.DI()?

Thanks!

Akka.DI.TestKit is used to test custom IoC container plugins (like Autofac, NInject etc.) for compatibility with Akka. They are not used for testing custom code.

If you want to mock Context.DI() you probably need to supply container and register your mocks in it.
