Topic #: 4

[All CTFL4 Questions]

Which of the following statements is true?

AFunctional testing focuses on what the system should do while non-functional testing on the internal structure of the system

BNon-functional testing includes testing of both technical and non-technical quality characteristics

CTesters who perform functional tests are generally expected to have more technical skills than testers who perform non-functional tests

DThe test techniques that can be used to design white-box tests are described in the ISO/IEC 25010 standard

Show Suggested Answer

Suggested Answer: B

Non-functional testing includes testing of both technical and non-technical quality characteristics. Non-functional testing is the process of testing the quality attributes of a system, such as performance, usability, security, reliability, etc. Non-functional testing can be applied at any test level and can use both black-box and white-box test techniques. Non-functional testing can cover both technical aspects, such as response time, throughput, resource consumption, etc., and non-technical aspects, such as user satisfaction, accessibility, compliance, etc. Therefore, option B is the correct answer.

Haha, D is so far off. Automating with a GUI tool? That's not what these techniques are about at all!

A sounds reasonable, but I'd go with C. Finding hidden defects is a key strength of experience-based testing.

D is just plain wrong. Automating test cases is not the primary goal of experience-based techniques.

B seems off to me. Isn't the test basis for white-box testing things like code, data structures, and control flow?
