ISTQB Certified Tester Advanced Level – Test Analyst (CTAL-TA) — Question 19

Which test technique is MOST closely associated with classification tree diagrams?

Answer options

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

Correct answer: B

Explanation

Decision table testing is the correct answer because it involves creating a table that outlines various input combinations and their expected outcomes, which aligns with the purpose of classification tree diagrams. The other options, while valid testing techniques, do not have a direct association with classification trees as they focus on different aspects of testing, such as user interactions (use case testing) or state changes (state transition testing).
