Using a state model, testers identify sequences of state transitions to test. Which of the following are valid state transition sequences for the weather station that should be tested? Select all that apply.
Correct Answer
(1) Shutdown - Running - Shutdown
(2) Configuring - Running - Testing - Transmitting - Running
(3) Running - Collecting - Running - Summarizing - Transmitting - Running
Explanation
The three valid state sequences from the chapter are: (1) Shutdown - Running - Shutdown; (2) Configuring - Running - Testing - Transmitting - Running; (3) Running - Collecting - Running - Summarizing - Transmitting - Running. These represent meaningful operational cycles of the weather station.
