Which of the following is non-functional testing ?
Correct answer: B. Performance testing
- A. Black box testing
- B. Performance testing
- C. Unit testing
- D. None of the mentioned
Explanation
Performance testing measures qualities such as response time, throughput, and scalability rather than checking a specific business function, so it is non-functional testing. Unit testing is usually functional testing at the smallest software-unit level, while black-box describes a test approach rather than a quality attribute.
