Why is it important to test all possible state transitions in state transition testing?
ATo reduce the number of test cases to a minimum
BTo test the system's performance under load
CTo check only the initial and final states
DTo ensure the system behaves correctly for every event in every state
Step-by-Step Solution
Solution:
Step 1: Understand the goal of state transition testing
The goal is to verify that the system responds correctly to every event from every possible state.
Step 2: Match the goal with the options
To ensure the system behaves correctly for every event in every state correctly states the importance of testing all transitions to ensure correct behavior.
Final Answer:
To ensure the system behaves correctly for every event in every state -> Option D
Quick Check:
Complete transition coverage = correct system behavior [OK]
Quick Trick:Test all transitions to catch hidden bugs [OK]
Common Mistakes:
Thinking testing only initial/final states is enough
Confusing transition testing with performance testing
Trying to minimize test cases by skipping transitions
