ISTQB CTFL-Foundation Exam - 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.

Decision testing is definitely a must-have here.

I feel like boundary value analysis is useful for edge cases, but I’m not sure if it complements decision table testing as well as decision testing does.

Decision table testing seems like a solid option since it can handle multiple conditions, but I’m torn between it and equivalence partitioning for the black box technique.

I think exploratory testing is great for finding unexpected issues, but I’m not confident it’s the right choice alongside statement testing for this scenario.

I remember we discussed decision testing being really effective for complex business rules, but I'm not sure if it pairs best with equivalence partitioning or decision table testing.

Hmm, I'm not sure. Statement testing and exploratory testing (option A) could also be a good approach to explore the system's behavior without getting too deep into the code. I'll have to weigh the pros and cons of each option.

I feel pretty confident about this one. Decision testing and decision table testing (option C) seem like a solid combo to handle the complex business rules and code structure they're describing.

I'm a bit confused by the wording of the question. What exactly do they mean by "complex business rules" and "many branches in the structure of the code"? That makes me hesitant about some of the options.

Okay, let's see. The question is asking for the best combination of a black box and a white box technique. I'm leaning towards option D - boundary value analysis and decision table testing.

This is a tricky one. I'll need to think carefully about the differences between black box and white box techniques and which ones would work best for this scenario.

Yeah, I agree with Deonna. Decision table testing is crucial for handling those complex business rules. And boundary value analysis is a must for finding any potential issues at the limits of the system.
