FSM-based testing

FSM-based testing uses a model called a Finite State Machine (FSM) to represent how a system behaves in different situations with various inputs. It maps out all possible states the system can be in and how it transitions from one state to another when inputs are received. Testing involves systematically providing inputs and verifying that the system transitions and outputs align with the FSM model. This approach helps identify errors and ensures the system functions correctly across all scenarios, making it a rigorous method for validating complex systems like software, hardware, or embedded devices.
