ISTQB Certified Tester Foundation Level v4.0 — Question 13

Which black-box technique should be used to verify different responses of the system, depending on its current conditions or previous history?

Answer options

• A. Use case testing
• B. Decision table testing
• C. State transition testing
• D. Equivalence partitioning

Correct answer: C

Explanation

State transition testing is the correct choice because it focuses on how the system behaves in different states and how transitions between those states affect outputs. The other options, like use case testing and equivalence partitioning, do not specifically address the impact of previous states or history on system responses.
