Resolving Conflicts with Implicit ActorRef
------------------------------------------
The :class:`TestKit` trait contains an implicit value of type :class:`ActorRef`
to enable the magic reply handling. This value is named ``self`` so that e.g.
anonymous actors may be declared within a test class without having to care
about the ambiguous implicit issues which would otherwise arise. If you find
yourself in a situation where the implicit you need comes from a different
trait than :class:`TestKit` and is not named ``self``, then use
:class:`TestKitLight`, which differs only in not having any implicit members.
You would then need to make an implicit available in locally confined scopes
which need it, e.g. different test cases. If this cannot be done, you will need
to resort to explicitly specifying the sender reference::
val actor = actorOf[MyWorker].start()
actor.!(msg)(testActor)
Using Multiple Probe Actors
