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

 Scrum is an agile development approach that incorporates the following practices:

• a project is divided into iterations called sprints, which are typically 2-4 weeks long
• each sprint starts with a planning meeting, where the team selects a subset of user stories from the product backlog to work on
• each sprint ends with a review meeting, where the team demonstrates the potentially releasable/shippable product increment to the stakeholders and collects feedback
• each sprint also includes a retrospective meeting, where the team reflects on the process and identifies areas for improvement123 References: 1: ISTQB® Foundation Level Agile Tester Syllabus, Section 2.1, Agile Software Development1; 2: ASTQB Agile Tester Certification Resources, Section 2.1, Agile Software Development2; 3: What is Agile? | Atlassian3

The best black box test design technique for verifying the accuracy of this user story is equivalence partitioning. Equivalence partitioning is a technique that divides the input domain of a system into classes or groups that are expected to behave similarly. By testing one value from each class, the tester can reduce the number of test cases while still achieving good coverage. In this case, the input domainof the system is the amount of income, which can be divided into classes based on the tax percentage applied to different income ranges. For example, if the tax percentage is 10% for income below 10,000, 20% for income between 10,000 and 20,000, and 30% for income above 20,000, then the equivalence classes are: low income (<10,000), medium income (10,000-20,000), and high income (>20,000). By testing one value from each class, such as 5,000, 15,000, and 25,000, the tester can verify that the system calculates the correct tax percentage for each income range. This technique is more efficient and effective than testing all possible values of income, or testing only one value of income, or testing the states of income entry, or testing the statements in income calculation. References: ISTQB Foundation Level Agile Tester Syllabus1, Section 2.3.1, page 19; ISTQB Foundation Level Agile Tester Extension Sample Exam Questions2, Question 5, page 6.

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 1.2.1, page 9; What is Whole Team Approach in Agile Testing?2, Section What is Whole Team Approach?; Continuous Integration3, Section What is Continuous Integration?; Effective User Stories - 3C’s and INVEST Guide4, Section The 3 C’s (Card, Conversation, Confirmation) of User Stories.
