ISTQB Exam CTFL-Foundation Topic 2 Question 34 Discussion

Actual exam question for ISTQB's CTFL-Foundation exam

Question #: 34
Topic #: 2

Your company is developing a system with complex business rules and many branches in the structure of its code components. You need to choose one black box technique and one white box technique for test case design.

Which one of the following offers the BEST choice?

AStatement testing and exploratory testing

BDecision testing and equivalence partitioning

CDecision testing and decision table testing

DBoundary value analysis and decision table testing

Show Suggested Answer

Suggested Answer: D

For a system with complex business rules and many branches, decision testing (a white-box technique) is appropriate because it ensures that each decision point (branch) in the code is tested. Equivalence partitioning (a black-box technique) complements this by ensuring that all functional areas (based on different inputs) are adequately tested. This combination provides thorough coverage of both the internal logic and the functional requirements of the system.

For a complex system with many code branches, I think option D is the best choice. Boundary value analysis and decision table testing can really help cover all the edge cases.
