Discuss ISQI CTAL-ATT Exam Topic 5 Question 77

What is the characteristic of a unit test that makes it ''deterministic''?

AIf it is run with the same conditions, it will get the same result each time

BIt tests the details of the code, including verifying all the possible areas of data handling

CIt tests only the targeted piece of functionality

DIt runs very fast, allowing many tests to be run quickly

Suggested Answer: A

Definition of 'Deterministic' in Unit Testing:

A deterministic test produces consistent results when executed under the same conditions.

Analyzing the Options:

A: Correctly describes deterministic behavior.

B: Refers to test coverage, not determinism.

C: Refers to atomicity, not determinism.

D: Speed is unrelated to determinism.

Aligned with ISTQB Agile Technical Tester syllabus emphasizing the need for tests to be consistent and predictable.

But what about C? It focuses on specific functionality, right?

I agree, A makes sense. Same input, same output every time.

I think A is the best choice. Consistency is key in tests.

Fast tests are great, but they don’t guarantee determinism!

King 2 months ago

Wait, are we sure A is the only factor?

Gayla 2 months ago

C makes sense, but I’m not sure it’s the main point here.

I think B is important too, but not for determinism.

Avery 2 months ago

A is definitely the right answer!

I’m a bit confused, but I remember that speed isn’t really what makes a test deterministic, so I don’t think it’s D.

Eveline 3 months ago

I feel like I’ve seen a question like this before, and I think it was about consistency, so A sounds right to me.

Geraldo 3 months ago

I’m not entirely sure, but I remember something about testing specific functionality being important. Maybe it’s C?

I think a deterministic test means it gives the same result every time under the same conditions, so I’d go with A.
