ISTQB-CTFL Exam - Topic 6 Question 26 Discussion

Actual exam question for ISTQB's ISTQB-CTFL exam

Question #: 26
Topic #: 6

Which of the following statements about testing in the context of an agile (iterative-incremental) development model is correct?

AUnit test and acceptance test ate the most important tests to make sure that the system works as expected.

BEach iteration of testing has to be completely finished before a new Iteration of development starts.

CRegression testing is necessary whenever a new Increment Is added to the existing system. D. Only certain types of non-functional and explorative testing are performed.

Show Suggested Answer

Suggested Answer: C

In the context of agile (iterative-incremental) development models, testing is integrated into the development process and occurs continuously throughout the lifecycle of the project. Agile testing emphasizes adaptability and the need for feedback at various stages of development.

Option C is correct because regression testing is indeed necessary whenever a new increment is added to the existing system. Agile development often involves frequent changes and additions to the codebase, which can potentially introduce new defects into previously tested code. Regression testing ensures that new changes have not adversely affected existing functionality.

Options A, B, and D present misconceptions about agile testing:

A is incorrect because, in agile, all types of testing (unit, integration, system, acceptance) are important and occur throughout the iteration, not just unit and acceptance tests.

B is incorrect because agile methodologies advocate for continuous integration and testing, where development and testing activities overlap and support each other throughout an iteration.

D is incorrect because agile methodologies encourage a wide range of testing types, including both functional and non-functional, as well as exploratory testing, to ensure a comprehensive quality assessment.

I vaguely remember that not all types of testing are done in every iteration, but I can't remember the specifics about non-functional testing.

I feel like regression testing is definitely important when adding new increments, but I’m not completely confident about the wording of that statement.

I think I saw a question about iteration and testing in one of our practice exams, but I can't recall if all testing needs to be finished first.

I'm a bit confused by the distinction between unit, acceptance, and other types of testing. I'll need to review my notes to refresh my memory on the agile testing approach.

Hmm, I'm not sure about this one. I'll have to think it through carefully. Maybe it's ListID since that would identify the specific list the subscriber is unsubscribing from.

Okay, let's see here. We need an attribute that will cause the class compilation to fail if a specific method is called. I'm thinking SysObsoleteAttribute might be the way to go, but I'll double-check the other options just to be sure.

Ha! Option B is clearly the funniest one. Imagine trying to completely finish an iteration of testing before moving on to the next one. That would be like trying to build a house one brick at a time.

Hmm, I'm not sure about that. I think option A might be more accurate, as unit and acceptance tests are the foundation for ensuring the system works as expected.
