ITPEC IP October 2019 — Question 48 of 100
White-box testing designs test cases by examining the program's internal structure. It targets statements, branches, conditions, paths, and loops to achieve defined structural coverage and reveal errors within the implementation logic.
Answer (d)
Why not others:
- regression testing checks that changes did not break previously working behavior
- system testing evaluates the complete system
- black-box testing derives cases from inputs, outputs, and specifications without using internal code structure
Key rule: White box tests implementation structure; black box tests externally observable behavior against specifications.
