5.5. State Transition Testing

Try these first

1. 1.

   Define what a transition is in the context of State Transition Testing.

   Hint

   What occurs when an event happens in the system?

2. 2.

   Give an example of a valid transition.

   Hint

   Think about user actions with an ATM.

3. 3.

   What is State Transition Testing primarily concerned with?

   • Validating database schema
   • Testing system transitions between states
   • Checking user interface design

   Hint

   Think about transitions and user actions.

4. 4.

   True or False: An invalid transition should be permitted in a well-designed system.

   • True
   • False

   Hint

   Consider what we expect from user interactions.

5. 5.

   Design a state transition model for a traffic light system that effectively manages state transitions.

   Hint

   Consider the logic of how traffic lights cycle.

6. 6.

   Analyze the consequences if the traffic light system allowed an invalid state transition (like Green to Red without Yellow).

   Hint

   Think about safety implications in traffic management.
