Implementing software solutions using finite state machines (FSMs) is a useful technique in many application areas, including compiler implementation and network protocols. This report examines possible implementation techniques for FSMs in the Smalltalk object-oriented system, and identifies techniques which best support the goals of generality, flexibility and software reuse.

Some systems interact with their environment at physically distributed interfaces, called ports, and in testing such a system it is normal to place a tester at each port. Each tester observes only the events at its port and it is known that this limited observational power introduces additional controllability and observability problems into testing. Given a multi-port finite state machine (FSM...
