Example project: Coding an elevator state machine with Akka FSM

[Tom Bray]

Hi folks,

I really fell in love with Akka when I discovered the Finite State Machine DSL and thought I'd share the love with an example project that demonstrates how to build an elevator state machine using TDD. 

Here's the project:  https://github.com/tombray/akka-fsm-examples

Here's the elevator FSM:  https://github.com/tombray/akka-fsm-examples/blob/master/src/main/scala/com/tombray/examples/akka/ElevatorActor.scala

And here are the tests:  https://github.com/tombray/akka-fsm-examples/blob/master/src/test/scala/com/tombray/examples/akka/ElevatorActorSpec.scala

Please let me know if you have any suggestions for improvements or ideas for future examples.

Cheers,

Tom

Thanks for that. I will definetly take a closer look. I've been looking for some nice example projects of FSM recently.

Hi Tom,

really nice example. Very easy to go through and grok the inner workings of the elevator. I have added couple of comments on commits in GitHub.
