ISTQB Certified Tester Advanced Level – Test Analyst (CTAL-TA) — Question 38
A car navigation system needs to be integrated in the overall car software. It is important to verify that the car navigation is functioning correctly once integrated. Thus functional correctness is considered to be important.
Which of the following techniques is most likely to support the required functional correctness testing? (Choose all that apply.)
Answer options
- A. State transition testing
- B. Multiple condition testing
- C. Vulnerability scan
- D. Heuristic evaluation
Correct answer: A, B
Explanation
State transition testing and multiple condition testing are both effective techniques for verifying functional correctness, as they assess how the system behaves under various conditions and states. In contrast, a vulnerability scan focuses on security weaknesses, and heuristic evaluation assesses usability rather than functional correctness.
