ISTQB ATM Exam - Topic 3 Question 71 Discussion

Actual exam question for ISTQB's ATM exam
Question #: 71
Topic #: 3
[All ATM Questions]

Assume you are currently working on a project developing a system where functional

requirements are very well specified. Unfortunately non-functional requirements do almost not exist.

You are the Test Manager. You have to choose a technique for test selection that allows testing of non-functional characteristics, especially reliability.

Which of the following techniques for test selection do you expect being most useful in this scenario?

Test condition analysis might be useful, but not my first choice.

I think ambiguity reviews could help too, but not as much.

Wait, can a model really cover all non-functional aspects?

A model-based technique is great for reliability testing!

Cause-effect graphing seems more suited for functional testing, right? I feel like it wouldn't help much with non-functional aspects like reliability.

Test condition analysis sounds familiar, but I can't recall if it specifically addresses reliability. I might need to double-check that.

I'm not entirely sure, but I think ambiguity reviews focus more on functional requirements rather than non-functional ones.

I remember studying that model-based techniques can help in defining how the system should behave under different conditions, especially for reliability.

Test condition analysis seems like the most straightforward option to me. If we can identify the key conditions and scenarios that impact reliability, we can focus our testing efforts there.

Ambiguity reviews could be a good way to try and uncover any hidden non-functional requirements that weren't properly documented. It's worth considering, even if it's not the most direct approach.

A model-based technique based on operational profiles sounds like it could be a good approach here. If we can create a model of how the system is expected to be used, that might help us identify reliability issues.

This seems like a tricky one. With the lack of non-functional requirements, I'm not sure which technique would be most useful for testing reliability. I'll have to think this through carefully.

Non-functional requirements? What is this, the Bermuda Triangle of software development? I say we just throw the whole project into the ocean and start over.

Cause-effect graphing? Really? That's like trying to catch a fish with a net made of string. A model-based technique is clearly the best option here.

I agree, a model-based technique is the way to go. It'll let us simulate real-world usage and put the system through its paces. Plus, it's better than relying on those sketchy non-functional requirements, or lack thereof.
