Which components are included in a run-to-completion step in order?

• A. Exit behavior of the source state, the transition effect, and the entry behavior of the target state
• B. Entry behavior only
• C. Exit behavior only
• D. The guard condition

Answer: (A)

Run-to-completion follows a specific sequence when a transition fires: you first execute the exit actions of the source state (and any states being exited along the path), then perform the transition’s own action (the transition effect), and finally execute the entry actions of the target state (and any states entered on the way). The guard condition is checked beforehand to decide if the transition can fire, but it isn’t part of the run-to-completion sequence itself. So the components included in a run-to-completion step in order are the exit behavior of the source state, the transition behavior, and the entry behavior of the target state.
