#Akka FSM Examples I really fell in love with Akka when I discovered its Finite State Machine DSL. I created this project to provide examples of how to use the FSM trait with your actors and how to test your state machines. One of the classic examples of a state machine is an elevator, so I thought I'd start there. I developed my Elevator test-first which allowed me to discover a nice design and to be confident as I refactored. What I ended up with is a fully functioning elevator that responds to requests to get on and off in a pretty efficient manner -- certainly more efficient than the real elevators in the building where I work! And it's just around 100 lines of code!
Please start by taking a look at the elevator itself: ElevatorActor.scala
And then walk through the tests that I wrote as I fleshed out the behavior: ElevatorActorSpec.scala
Soon, I'll add an ElevatorDispatcherActor to manage multiple elevators in the same building and determine the best elevator to service incoming requests.
