Discuss ISQI CTFL_Syll2018 Exam Topic 2 Question 122

A "functional test" is...

A... a test focused on the efficiency of the system

B... a dynamic test for which the tests are based on the specification of the test object.

C... a static comparison of test and requirements specification of a test object

D... a test for which the test cases and test data are based on the structure of the test object

Suggested Answer: B

A functional test is a dynamic test for which the tests are based on the specification of the test object. This means that the test cases and test data are derived from the functional requirements, use cases, user stories, or other sources that describe the expected behavior and functionality of the system under test. A functional test is not focused on the efficiency of the system (that would be a performance test), nor is it a static comparison of test and requirements specification (that would be a review or inspection), nor is it based on the structure of the test object (that would be a structural test).

C seems off. Functional tests are more about behavior, not static comparisons.

I feel like A makes sense too, but it’s not the main focus.

I think B is the right choice. It’s all about the specs.

Not sure about B, sounds too vague to me.

Wait, I always thought it was A!

Totally agree with B! That's how we do it.

I thought functional tests were more about efficiency?

B is correct! It's all about the specs.

I keep mixing up functional and structural tests; I feel like option D might be right, but I’m not confident about that.

I practiced a similar question, and I think functional testing is definitely about dynamic testing, so I would go with B again.

Herminia 7 months ago

I'm not entirely sure, but I remember something about functional tests being related to user requirements, which sounds like option A could be relevant too.

I think a functional test is more about how the system behaves according to its specifications, so I might lean towards option B.
