CTFL-AT Certified Tester Foundation Level Agile Tester Questions and Answers

 Behavior-Driven Development (BDD) is a software development approach that allows a developer to define accurate unit tests focused on business needs. BDD uses a common language that is understandable by both technical and non-technical stakeholders, such as Given-When-Then scenarios.BDD helps to align the development and testing activities with the customer expectations and business goals . References:

Regression of software is the risk that a change in one part of the software causes a defect in another part of the software that was previously working correctly. Regression of software is a high risk in agile projects because there is code churn due to change in business needs over several sprints. Code churn is the amount of code that is added, modified, or deleted in a software project over time. Code churn can indicate the volatility and complexity of the software, and the frequency and magnitude of the changes. In agile projects, code churn can be high because the business needs and the user requirements can change rapidly and frequently over several sprints, which are short iterations of development and testing. This means that the software is constantly evolving and adapting to the changing needs, and that the existing functionality and quality may be affected by the new or modified code. Therefore, regression of software is a high risk in agile projects, and it requires effective testing strategies and techniques to prevent, detect, and fix the regression defects. References: ISTQB® Foundation Level Agile Tester Syllabus1, Section 2.3.2, page 17; ISTQB® Glossary of Testing Terms2, version 4.0, pages 36 and 55

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.

 According to the ISTQB Tester Foundation Level Agile Tester syllabus, an agile task board is a visual tool that displays the status of the work items in an agile sprint. The task board typically shows the user stories, tasks, and their progress from “to do” to “done”. The task board helps the agile team to monitor and coordinate their work, and to communicate with stakeholders. Therefore, the examples that represent activities that would likely be managed on an agile task board for the third sprint are those that are related to the user stories, tasks, and their progress in the current sprint. Option A is the correct answer, as it contains two examples of such activities: running an acceptance test for a user story, and automating regression tests. These are both tasks that are part of the testing process in the current sprint, and their status can betracked on the task board. Option B is not a correct answer, as it contains two examples of activities that are not related to the current sprint: designing the features planned for the next sprint, and participating in training in preparation for the fourth sprint. These are both activities that are part of the planning or learning process for the future sprints, and they are not managed on the task board. Option C is also not a correct answer, as it contains two examples of activities that are not related to the current sprint: participating in training in preparation for the fourth sprint, and producing a daily progress report for the agile team members. These are both activities that are part of the learning or reporting process, and they are not managed on the task board. Option D is also not a correct answer, as it contains two examples of activities that are not related to the current sprint: designing the features planned for the next sprint, and producing a daily progress report for the agile team members. These are both activities that are part of the planning or reporting process, and they are not managed on the task board. References: ISTQB Tester Foundation Level Agile Tester syllabus, section 2.1.1, page 14; ISTQB Tester Foundation Level Agile Tester syllabus, section 2.1.2, page 15; ISTQB Tester Foundation Level Agile Tester syllabus, section 2.2.1, page 16; ISTQB Tester Foundation Level Agile Tester syllabus, section 2.2.2, page 17.

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.

According to the ISTQB Tester Foundation Level Agile Tester syllabus, acceptance criteria are a set of conditions that a user story must satisfy to be accepted by the customer or stakeholder. Acceptance criteria should be testable, meaning that they can be verified by objective measurements or observations. Testable acceptance criteria should be clear, unambiguous, complete, and consistent. Therefore, option A is the best example for testable acceptance criteria, as it specifies a clear and measurable condition for the input value of the ID field. Option B is not a good example for testable acceptance criteria, as it is vague and does not define any specific condition or expectation for the interface to External System. Option C is not a good example for testable acceptance criteria, as it is incomplete and does not specify what the specific authorization level is or how it is determined. Option D is not a good example for testable acceptance criteria, as it is subjective and not measurable. What is clear and attractive for one user may not be for another. References: ISTQB Tester Foundation Level Agile Tester syllabus, section 1.1.1, page 7; ISTQB Tester Foundation Level Agile Tester syllabus, section 1.1.2, page 8; ISTQB Tester Foundation Level Agile Tester syllabus, section 3.1.1, page 23; ISTQB Tester Foundation Level Agile Tester syllabus, section 3.1.2, page 24.

 A task management tool is a software application that helps agile teams plan, organize, and monitor their work. A task management tool typically allows the team to create, assign, prioritize, update, and track user stories, tests, and other tasks that are part of the agile project. A task management tool can also provide various views and reports to visualize the progress and status of the project, such as Kanban boards, burndown charts, velocity charts, etc. Some examples of task management tools are Jira, Trello, Asana, and Monday.com12345. References: ISTQB® Foundation Level Agile Tester Syllabus, Section 2.1.1, page 13; ASTQB Agile Tester Certification Resources, Section 2.1.1, page 13.

The Agile Manifesto is a declaration of four values and twelve principles that guide the Agile software development approach12. The four values of the Agile Manifesto are12:

• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

These values emphasize the importance of human collaboration, working product, customer feedback, and adaptability over rigid processes, extensive documentation, fixedcontracts, and predefined plans. The values do not imply that the items on the right are not important, but rather that the items on the left are more important and should be prioritized.

Therefore, the statement that is NOT a value from the Agile Manifesto is B, as it contradicts the first value of the Agile Manifesto. The correct statement should be “Individuals and interactions over processes and tools”. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, page 10; ISTQB Agile Tester Sample Exam2, question 1.

An Agile task board is a visual framework to display and sync up on the tasks moving between production steps. It is usually applied to the two most popular Agile development frameworks — Kanban and Scrum. Used by software developers and project managers, an Agile board helps manage workloads in a flexible, transparent, and iterative way1. An Agile task board provides a detailed visual representation of the whole team’s status, showing which tasks remain to be started, which are in progress, and which are done. It also helps to track the progress of the current sprint, identify bottlenecks, and facilitate collaboration and communication among team members2. References:
