ISQI Certified Tester Foundation Level — Question 31

Which of the following test design techniques is not a black box technique?

Answer options

• A. Equivalence partitioning
• B. State transition testing
• C. Boundary value analysis
• D. Statement coverage

Correct answer: D

Explanation

Statement coverage is a white box testing technique that focuses on the internal structure of the code, ensuring every statement is executed. In contrast, equivalence partitioning, state transition testing, and boundary value analysis are all black box techniques that concentrate on the functionality of the software without knowledge of its internal workings.
