It is no secret that I love types and have been using Akka for a number of years, so I could not wait to play with Akka Typed. Akka Typed is quite different from its untyped cousin. Every time I reach for my favorite class or idiom I find it works differently or maybe doesn’t even exist at all. One of the big differences is that there is not TestKit for typed actors.
