A tester on an Agile project typically performs the following tasks12:

Implementing test strategy: A tester helps to define and implement the test strategy for the Agile project, which includes the test approach, test levels, test types, test techniques, test tools, test environment, test data, test metrics, and test documentation.

Measuring and reporting test coverage: A tester measures and reports the test coverage of the product features and quality attributes, such as functionality, usability, performance, security, etc. Test coverage can be expressed in terms of test cases, test scenarios, test sessions, test conditions, test data, code, etc.

Coaching development team in relevant aspects of testing: A tester coaches the development team in relevant aspects of testing, such as test design, test execution, test automation, test-driven development, behavior-driven development, exploratory testing, etc. A tester also helps the development team to improve their testing skills and practices.

The following tasks are not typically performed by a tester on an Agile project:

Documenting business requirements: Business requirements are usually documented by the product owner or the business analyst, not by the tester. The tester may review and provide feedback on the business requirements, but the tester is not responsible for documenting them.

Executing test-driven development tests: Test-driven development tests are usually executed by the developers, not by the tester. The tester may assist the developers in creating and reviewing the test-driven development tests, but the tester is not responsible for executing them.

Therefore, the correct answer is C, as it contains the tasks that are typically performed by a tester on an Agile project. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, pages 14-15, 18-19, 22-23; ISTQB Agile Tester Sample Exam2, question 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.

 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.

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 highbecause 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

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.

Comprehensive and Detailed Explanation From Exact Extract:

FromCTFL-AT Syllabus v4.0, Section 3.2Test-Driven Development, and 1.3The Whole-Team Approach, testers:

"Collaborate in test-related activities including test case creation, exploratory testing, and user story clarification."

"Unit tests are typically the responsibility of developers, especially in TDD practices."

Therefore,Option Aisleast likely, asunit test tracking in TDDis primarily adeveloper responsibility, not a tester's routine task.

Options B, C, and D all describekey Agile tester activities, such asmaintaining regression tests,collaborating with developers, andparticipating in specification workshops (BDD/ATDD practices).

Continuous integration is a practice of integrating code changes frequently and automatically into a shared repository, and running automated tests to verify the integration. Continuous integration can introduce some risks to the testing process, such as:

Testers sometimes have too many builds to test, which reduces the quality of testing. This can happen when the code changes are too frequent or too large, and the testers do not have enough time or resources to test each build thoroughly. This can lead to missed defects, incomplete test coverage, and reduced confidence in the product quality.

Testers sometimes have to deal with unstable or broken builds, which affects the testability of the product. This can happen when the code changes introduce errors or conflicts that cause the build to fail or malfunction. This can waste the testers’ time and effort, and delay the feedback cycle.

Testers sometimes have to cope with changing requirements and priorities, which affects the test planning and execution. This can happen when the stakeholders or customers provide new or modified requirements or feedback during the development cycle. This can require the testers to adapt their test strategy, test cases, and test data accordingly, and to balance the testing of new features and regression testing of existing features. References: ISTQB® Foundation Level Agile Tester Syllabus1, Section 2.2.3, page 14; ISTQB® Glossary of Testing Terms2, version 4.0, page 15.

Test automation is essential for agile projects, as it enables fast and frequent feedback on the quality of the product. Without test automation, it would be very difficult to ensure high quality in an agile project, as manual testing would be too slow and costly to keep up with the pace of development12. Automated acceptance tests are one of the key types of test automation on agile projects, as they verify that the user stories are implemented correctly and that the product meets the customer’s expectations. Automated acceptance tests are run regularly as part of the continuous integration full system build, and the results provide feedback on the overall product quality12. Therefore, statements 2 and 5 are correct with regards to test automation on agile projects. References: 1: ISTQB® Foundation Level Agile Tester Syllabus, Section 3.3.1, Test Automation1; 2: ASTQB Agile Tester Certification Resources, Section 3.3.1, Test Automation2
