Discuss ISQI CTFL_Syll_4.0 Exam Topic 1 Question 18

Which of the following statements about TDD, BDD and ATDD is true?

ARefactoring is a practice that is an integral part of TDD and is applied both to tests and to code written to satisfy those tests

BATDD is a black-box test design technique that is applicable exclusively at acceptance test level

CBDD is a developer practice where business stakeholders are not usually involved as the tests are directly written at unit/component test level

DATDD is the practice of running the automated acceptance tests as part of a continuous integration process

Suggested Answer: B

A failure is an event in which a component or system does not perform a required function within specified limits1.A requirement is a condition or capability needed by a user to solve a problem or achieve an objective2. In this case, the requirement is that the diagnostics tests should execute in less than 2 seconds. Therefore, any event that violates this requirement is a failure. The only option that clearly violates this requirement is B. The diagnostic tests take too much time to execute. If the diagnostic tests take more than 2 seconds to complete, then they do not meet the specified limit and thus fail. The other options are not necessarily failures related to the specified requirement. Option A. The diagnostic tests fail to start after a system reset is a failure, but not related to the time limit. It is related to the functionality of the self-diagnostics module. Option C. The diagnostic tests that measure the speed of the memory, fail is also a failure, but not related to the time limit. It is related to the accuracy of the memory tests. Option D. The diagnostic tests fail due to incorrect implementation of the test code is also a failure, but not related to the time limit. It is related to the quality of the test code.Reference=ISTQB Certified Tester Foundation Level Syllabus v4.0,Requirements Engineering Fundamentals.

D sounds right, CI and ATDD go hand in hand!

Chu 11 months ago

Wait, is B really only for acceptance level? That seems off.

Viki 11 months ago

ATDD is more than just acceptance tests, right?

Crista 11 months ago

I disagree with C, BDD involves stakeholders for sure.

Amie 11 months ago

A is definitely true, refactoring is key in TDD!

Dorothy 12 months ago

I recall that ATDD is part of the CI process, but I'm not certain if that's the main focus of the practice.

Katlyn 12 months ago

I practiced some questions on BDD, and I feel like business stakeholders are usually involved, so that option seems off to me.

Una 12 months ago

I think ATDD is related to acceptance testing, but I'm not clear if it's strictly a black-box technique.

Marge 1 year ago

I remember that TDD definitely involves refactoring, but I'm not sure if it's also about tests and code.

Leonardo 1 year ago

I'm not sure if BDD is just for unit/component tests or if it involves business stakeholders as well. I'll have to think through that one carefully.

Cristal 1 year ago

ATDD is about running automated acceptance tests as part of the CI process, so I think option D is the right choice here.

Regenia 1 year ago

Refactoring is definitely a key part of TDD, so I'm pretty confident that option A is the correct answer.

Gianna 1 year ago

Hmm, I'm a bit confused about the differences between these practices. I'll need to review my notes to make sure I can distinguish them properly.

Norah 1 year ago

This question seems straightforward, I think I have a good understanding of the differences between TDD, BDD, and ATDD.

Malcom 1 year ago

Okay, let me break this down step-by-step. The key is to focus on eliminating cross-area coverage, weak coverage, and PCI mode 3 conflicts. I think I can work through this systematically.

Gilma 1 year ago

Hmm, this seems straightforward. I think the key is to use the superuser mode and the remove user command with the user's index number.

Refactoring? More like 'reFUNktoring'! Amirite, folks? *crickets* Oh, come on, that was a good one!

B) ATDD may start at the acceptance test level, but it can also be applied at the unit and component test levels. Keeps the focus on the business needs.

Francoise 1 year ago

C) Nah, BDD is all about collaboration between devs, QAs, and business stakeholders. The whole team works together to define the acceptance criteria.

Junita 1 year ago
