Scala Actor Examples with Unit Tests

This project contains examples of how to create and unit test Akka actors. It consists of two simple actors:

1. A Calculator which does stateless arithmetic.
2. An Accumulator which statefully accumulates values passed to it.

The CalculatorSpec unit tests show how to test actors. The Calculator companion object also contains a main function that is an example of how to use for-comprehension on futures.

The AccumulatorSpec unit tests show how to write unit tests which access an actor's internals.
