CTFL-AT Exam Dumps - Certified Tester Foundation Level Agile Tester

Comprehensive and Detailed Explanation From Exact Extract:

From theCTFL-AT Syllabus v4.0, Section 2.1User Stories and Acceptance Criteria, it states:

"Acceptance criteria are defined collaboratively and refined during the conversation to ensure mutual understanding. They may be added or updated as new insights emerge."

This supportsOption D, which reflects how acceptance criteria evolveduring conversations— a key component of the"Card, Conversation, Confirmation"model.

Option Ais incorrect — the user story istestable, especially with the acceptance criterion.

Option Bis false — the story provides clear user value (printed hard copy for daily records).

Option Cis misleading — the Given-When-Then formatsupportsdiscussions; it doesn’t replace them.

FromCTFL-AT Syllabus v4.0, Section 3.2Test-Driven Development, and Section 3.4Testing Quadrants:

"TDD focuses on writing unit tests before code is implemented. These are technology-facing tests that support the team and are categorized under Q1."

Therefore,Option Dis correct.

Option Ainvolves performance/security testing.

Option B and Cinvolvebusiness-facing tests, not applicable to TDD.

The Test Pyramid is a model for organizing tests in a way to make the process of testing faster, efficient and cost-effective. This model focusses on getting maximum functional testing getting covered by faster and less brittle tests like Unit and API tests1. The main benefit of the Test Pyramid is that it helps in evaluating the amount of test cases needed for each level of testing. The Test Pyramid suggests that the number of test cases should decrease as we move up the pyramid, from unit tests to integration tests to end-to-end tests. This is because unit tests are more granular, isolated, and easy to write and maintain, while end-to-end tests are more complex, dependent, and brittle. The Test Pyramid also helps in balancing the test coverage and the test execution time, as unit tests provide high coverage and low execution time, while end-to-end tests provide low coverage and high execution time. By following the Test Pyramid, teams can optimize their testing efforts and resources, and ensure that they have a sufficient and effective test suite for their software. References: ISTQB® Foundation Level Agile Tester Syllabus, Section 2.2.1, page 16; ASTQB Agile Tester Certification Resources, Section 2.2.1, page 16; What is Test Pyramid : Getting started with Test Automation Pyramid, The Practical Test Pyramid - Martin Fowler, Testing Pyramid: What Is It and How To Use It | Solvd.

FromCTFL-AT Syllabus v4.0, Section 3.2Test-Driven Development, it states:

"Test-Driven Development (TDD) is a practice where test cases are written before the code is developed. Typically, these tests are automated, and the code is written to make the tests pass."

This directly matchesOption A, making it the correct and complete answer.

Let’s review the other options:

Option Bdescribes atest strategy, not TDD.

Option Cis a definition ofAgile software development, not TDD.

Option Ddescribesexploratory testing, not TDD.

From theCTFL-AT Syllabus v4.0, Section 4.2Continuous Integration, it states:

"Continuous integration involves integrating code into a shared repository several times a day. Each integration is verified by an automated build and automated tests."

Hence,Option D—at least once a day— correctly reflects best practice in continuous integration.

Option A(once per iteration) andB,Care far too infrequent to meet the goals of CI.

The objective is to detect integration issuesearly and often, which is only achievable throughdaily (or more frequent)integrations.

FromCTFL-AT Syllabus v4.0, Section 3.4The Testing Quadrants, it states:

"The Agile testing quadrants are used to ensure that the team considers all important test types and levels during an Agile project. The quadrants categorize tests by their purpose (support development, critique the product) and by the type of feedback (business-facing vs technology-facing)."

Thus,Option Ccorrectly reflects theuse and purposeof the quadrants as aguidance tool, not a fixed sequence or hierarchy.

Option AandBare incorrect — the quadrants arenot mapped to strict levels or chronological order.

Option Dis false —risk is not the basis for quadrant numbering.

The test charter for the exploratory testing session is focused on buying a bus ticket, not a parking ticket. Therefore, any defect related to the payment for parking ticket is out of scope for the given test charter. The other defects are related to the functionality, usability, or reliability of buying a bus ticket, which are in scope for the test charter. References: ISTQB Certified Tester Foundation Level Agile Tester Extension Syllabus, Version 2014, Section 2.3.2 Exploratory Testing1, Section 2.3.2.1 Test Charter2; ISTQB Glossary of Testing Terms, Version 3.2, 2017, Definition of Test Charter3

 The Agile processes promote early and frequent feedback from the customers, users, testers, developers, and other stakeholders involved in the project. This feedback helps to ensure that the product meets the expectations and needs of the customers and users, and that the development process is continuously improved and adapted to the changing requirements and environment. However, increasing the frequency of feedback and communication does not eliminate all communication problems, as there may still be issues such as misunderstandings, misinterpretations, conflicts, or cultural differences that need to be resolved. Therefore, the statement D is not true, as it implies that communication problems are completely avoided by the Agile processes. References: ISTQB Foundation Level Agile Tester Syllabus1, Section 1.2.1, page 9; ISTQB Foundation Level Agile Tester Extension Sample Exam Questions2, Question 4, page 5.
