ITPEC IP April 2023 Question 48
ITPEC IP April 2023 — Question 48 of 100
Testing only inputs and expected outputs without access to internal structure is black-box testing. Test cases are derived from requirements and observable behavior, so the tester checks whether common transactions and boundary or error cases produce correct results without considering code paths.
Answer (c)
Why not others:
- (a) Inspection is a formal static review of work products
- (b) Walk-through is a peer review often led by the author
- (d) White-box testing uses knowledge of internal control flow, statements, branches, or paths
Key rule: Black box tests behavior from the outside; white box tests implementation structure from the inside.
