Actual exam question for BCS's CTFL4 exam

Question #: 30
Topic #: 2

Which of the following is a test-first approach, where tests that express a shared understanding from stakeholders of how the application is expected to work, are first written in business-readable language (following the Given/When/Then format), and then made executable to drive development?

ATest-Driven Development (TDD)

BAcceptance Test-Driven Development (ATDD)

CBehavior-Driven Development (BDD)

DDomain-Driven Design (DDD)

Show Suggested Answer

Suggested Answer: C

This answer is correct because Behavior-Driven Development (BDD) is a test-first approach, where tests that express a shared understanding from stakeholders of how the application is expected to work, are first written in business-readable language (following the Given/When/Then format), and then made executable to drive development. BDD is a collaborative approach that involves testers, developers, business analysts, product owners, and other stakeholders in defining the expected behavior of the application using scenarios that describe the preconditions, actions, and outcomes of the application. BDD scenarios are written using a domain-specific language (DSL) that can be translated into executable test cases using tools such as Cucumber or SpecFlow. BDD aims to improve communication, collaboration, and feedback among the team members, and to deliver software that meets the customer's needs and expectations.Reference: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 3.1.1.4

TDD is more about writing tests after the code, right?

I’m leaning towards ATDD since it emphasizes writing tests in business language first, but I need to double-check my notes on that.

I feel like the Given/When/Then format is more closely related to BDD, but I could be mixing it up with TDD.

I remember practicing a question about ATDD, which focuses on stakeholder collaboration. Could that be the right answer here?

I think this question is about a testing approach, but I'm not entirely sure if it's TDD or BDD. They both seem similar.

I think the key here is the emphasis on a shared understanding with stakeholders. That points to Acceptance Test-Driven Development (ATDD) as the best fit for this question.

I'm pretty confident that the answer is Behavior-Driven Development (BDD). The Given/When/Then format and the focus on business-readable tests are the key characteristics that match the question.

I'm a bit confused on the distinction between ATDD and BDD. They both seem to involve writing tests first, but I'll need to review the details to be sure which one fits this description better.

Okay, the question is asking about a test-first approach where the tests are written in a business-readable format. That sounds like Behavior-Driven Development (BDD) to me.

Yes, BDD does use Given/When/Then format. So the answer should be C) Behavior-Driven Development (BDD).

But doesn't BDD use business-readable language like Given/When/Then?

I'm feeling lucky today, so I'm going with C. BDD. It's got that fancy Given/When/Then thing going on, so it must be the right answer. Fingers crossed!

I'm just gonna go with the flow and pick B. ATDD. Sounds like the most relevant approach for this question. And hey, at least it's not multiple-choice math!

I'm going with C. BDD is the one that uses the Given/When/Then format to capture the expected behavior, right? Seems like the best fit here.

Definitely B. ATDD is all about writing executable tests based on stakeholder requirements first, and then driving the development process. No-brainer!
