ITPEC FE Morning October 2021 Question 48
ITPEC FE Morning October 2021 — Question 48 of 80
Black Box Testing — test data is based on external specifications, not code structure.
- •Black box testing treats the program as an opaque box — testers only know inputs and expected outputs from the specification
- •Test data is created based on external specifications (requirements, functional specs)
Why not others:
- (a) branch coverage — white box technique (requires knowledge of code branches)
- (b) condition coverage — white box technique (requires knowledge of Boolean conditions in code)
- (d) program structures — white box approach (test design follows internal code structure)
Key rule: Black box = specification-based; White box = code/structure-based.
