ISQI ISTQB Certified Tester - Foundation Level Extension - Agile Tester 認定 CTFL-AT 試験問題 (Q17-Q22):
質問 # 17
Which of the following statements about the test pyramid is true?
- A. The test pyramid emphasizes having more automated tests at the higher test levels and a decreasing number of them at the lower test levels
- B. The test pyramid concept states that every software system consists always of four different test levels (unit, integration, system, acceptance)
- C. The test pyramid concept is based on the principle of eliminating defects as early as possible in the software lifecycle
- D. The test pyramid consists of four test levels with business-facing tests at the bottom of the pyramid and technology-facing tests at the top
正解:C
解説:
Comprehensive and Detailed Explanation From Exact Extract:
FromCTFL-AT Syllabus v4.0, Section 4.1The Test Pyramid, it states:
"The test pyramid concept encourages more tests at lower levels (e.g., unit tests), with fewer tests at higher levels (e.g., system or UI tests), in order to find and fix defects as early as possible." Therefore,Option Ais correct - thetest pyramid supports early defect detectionthrougha high volume of lower-level automated tests.
* Option Bis incorrect - thetest pyramid emphasizes more tests at lower levels, not higher.
* Option Cis incorrect - Agile doesn't mandate four specific levels in every system.
* Option Dmisrepresents the pyramid -technology-facing tests (e.g., unit tests)areat the bottom, not the top.

Learning Objective (K2) - Understand the purpose of the test pyramid
質問 # 18
Which of the following statements would you expect to be the MOST direct advantage of the whole-team approach?
- A. Capitalizing on the combined skills of business representatives, testers and developers working together to contribute to project success.
- B. Reducing the involvement of business representatives because of the increased communication and collaboration between testers and developers.
- C. Avoiding requirements misunderstandings which may not have been detected until later in the development cycle when they are more expensive to fix.
- D. Having at least once a day an automated build and test process that detects integration errors early and quickly.
正解:A
解説:
The whole-team approach is a principle of agile testing that involves everyone with different knowledge and skills to ensure project success. The whole-team approach means that the business representatives, testers, and developers work together in every step of the development process, from planning to delivery. The whole- team approach aims to enhance communication and collaboration within the team, leverage the various skill sets of the team members, and make quality everyone's responsibility12. Therefore, the statement C is the most direct advantage of the whole-team approach, as it captures the essence of the principle and its benefits.
The other statements are not directly related to the whole-team approach, or are incorrect. Statement A is about continuous integration, which is a practice of agile development that involves having at least once a day an automated build and test process that detects integration errors early and quickly. Continuous integration is not a direct consequence of the whole-team approach, although it may be facilitated by it13. Statement B is about avoiding requirements misunderstandings, which may be a benefit of the whole-team approach, but not the most direct one. The whole-team approach does not only focus on requirements, but also on design, implementation, testing, and delivery. Moreover, avoiding requirements misunderstandings may also depend on other factors, such as the quality of the user stories, the use of acceptance criteria, and the feedback from the customers and users14. Statement D is incorrect, as it contradicts the whole-team approach. The whole- team approach does not reduce the involvement of business representatives, but rather increases it. Business representatives are an integral part of the whole-team approach, as they provide the vision, the value, and the validation of the product. They collaborate with the testers and developers to define the features, prioritize the backlog, and verify the outcomes12. References: ISTQB Foundation Level Agile Tester Syllabus1, Section

質問 # 19
Which two of the following statements are CORRECT with regards to test automation on agile projects?
1) Every test developed for past iterations is kept and executed as part of a regression suite for each new release of code.
2) It would be very difficult to ensure high quality in an agile project without test automation.
3) Automated acceptance tests are run regularly as part of the continuous integration full system build.
4) Automated regression suites are only run for the final release of code.
5) In agile projects, the results from automated acceptance tests provide feedback on the overall product quality.
- A. 2, 3
- B. 1, 3
- C. 3, 4
- D. 2, 5
正解:D
質問 # 20
What is the definition of agile software development?
- A. A framework to describe the software development lifecycle activities from requirements specification to maintenance where test planning of the various test levels is done as soon as the test basis is ready
- B. Testing carried out informally where no formal test preparation or execution takes place, no recognized test design technique is used and there are no expectations for results.
- C. A way of developing software where the test cases are developed, and often automated, before the software under test is developed.
- D. A group of software development methodologies based on iterative incremental development with self- organizing cross-functional teams who cooperate to define requirements and to implement the solution.
正解:D
解説:
Agile software development is a term that encompasses a group of software development methodologies that are based on iterative incremental development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. Agile methods promote adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourage rapid and flexible response to change. Some examples of agile methods are Scrum, Extreme Programming (XP), Kanban, and Lean Software Development. References:

質問 # 21
Which of the following activities are done in release planning?
1) Identifying testable user stories with acceptance criteria.
2) Elaborating the user stories into tasks.
3) Prioritizing the user stories.
4) Creating acceptance tests for the user stories.
5) Analyzing risks for each of the user stories.
6) Performing high level estimation for the release.
- A. Activities 2, 3 and 5
- B. Activities 2 and 4
- C. Activities 1, 4 and 6
- D. Activities 1, 3 and 6
正解:D
解説:
Explanation
Release planning is a process of defining the scope and timeline for an iterative or incremental product development project. It is used in agile or hybrid projects where a mid- to long-term planning of the product or system development or integration is required12. Release planning involves the following activities:
Identifying testable user stories with acceptance criteria. User stories are short descriptions of the features or functionalities that the customer or user wants from the product. Acceptance criteria are the conditions that must be met for the user story to be considered done and acceptable. Identifying testable user stories with acceptance criteria helps to define the scope and quality of the release13.
Prioritizing the user stories. User stories are prioritized based on the value they deliver to the customer or user, as well as the dependencies, risks, and costs associated with them. Prioritizing the user stories helps to determine the order and frequency of the releases13.
Performing high level estimation for the release. High level estimation is a technique to estimate the effort, time, and resources needed to complete the user stories in the release. High level estimation can be done using various methods, such as analogy, expert judgment, planning poker, etc. Performing high level estimation for the release helps to set realistic and achievable goals and deadlines13.
Therefore, activities 1, 3 and 6 are done in release planning. Activities 2, 4 and 5 are done in iteration planning, which is a more detailed and short-term planning of the work to be done in each iteration or sprint13.
