What do state transition tables demonstrate?

State transition tables are a powerful tool used in software testing and design to represent how a system behaves in response to various inputs or events. They capture the dynamic behavior of a system by illustrating its states, transitions between those states, the events that provoke those transitions, and the actions that result from each transition.

When considering the answer, it becomes clear why stating "All of the above" is accurate. First, state transition tables indeed show the events that trigger transitions, which allows testers and developers to understand what inputs or occurrences cause the system to change from one state to another. Secondly, they demonstrate the actions that result from a transition, outlining what happens as the state of the system changes. Lastly, they provide an overview of different paths through the system by illustrating the various states and the transitions connecting them, highlighting how the system can navigate from one state to another depending on the events received.

By encompassing all these elements, state transition tables offer a comprehensive view of system behavior, making it easier to analyze and validate the system's performance and correctness in response to different conditions. This multifaceted portrayal is essential for ensuring that the system operates as intended across all potential scenarios.
