Comprehensive and Detailed Explanation From Exact Extract:

FromCTFL-AT Syllabus v4.0, Section 3.1Exploratory Testing, it defines atest charteras:

"A mission statement defining what to test, how it can be tested, and what issues to look for. Effective charters support focused yet flexible exploration."

Option Bis the best because it specifies:

Thearea of the system under test

Theparameters involved

Theapproach(combinations)

Thegoal(discover unexpected effects)

Option Afocuses only onone parameter.

Option Cistoo vague.

Option Dis tooprescriptiveand limits exploration.

 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 be tracked 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 taskboard. 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.

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).

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.

FromCTFL-AT Syllabus v4.0, Section 2.1Acceptance Criteria and Testability, and Section 3.1:

"Acceptance criteria may also address non-functional quality characteristics such as reliability, performance, and usability."

The criterion referencesfailure rate over time, which is areliability attribute, makingOption D (Quality characteristics)the correct answer.

Option A(Scenarios) refers to usage paths.

Option Brefers to functional correctness.

Option Crefers to interface interaction points.

FromCTFL-AT Syllabus v4.0, Section 4.3Test Automation and Continuous Integration, it states:

"Short iterations and continuous integration require well-designed automated test suites, and teams should adopt good practices for test design and implementation from the start."

OptionBis correct because it highlights theneed for proactive test design practicesto handle frequent changes — a key Agile challenge.

Option Amixes concepts:version controlrelates to code, not directly to regression management.

Option Cis incorrect — regressionrisk increaseswhen code is modified.

Option Dis misleading — tests may becomeobsoleteor needrefactoring, sono test is permanently untouchable.

The 3C concept of user stories consists of three elements: card, conversation, and confirmation12. The card is a written description of the user story that captures the essence of the feature or functionality from the user’s perspective. The conversation is a dialogue between the product owner and the development team to clarify the details, assumptions, and expectations of the user story. The confirmation is a set of criteria or tests that verify that the user story is implemented correctly and meets the user’s needs12. Therefore, by applying the 3C concept, the correct statement is A, as the conversation should include the acceptance criteria discussion. This will help the team to understand the scope, priority, and value of the user story, as well as the conditions of satisfaction that the product owner expects12. The other statements are incorrect, as they violate the 3C concept. Statement B is wrong, as the card should contain the user story, not the requirements. The user story is a brief and informal way of expressing the user’s goal and benefit, while the requirements are more detailed and specific descriptions of how the software should work. The requirements can be added later as part of the conversation or confirmation12. Statement C is wrong, as the product owner has written a user story, but confirmation is still needed. The confirmation is a vital part of the 3C concept, as it ensures that the user story is testable, measurable, and verifiable. The confirmation also helps to avoid ambiguity, misunderstanding, or disagreement between the product owner and the development team12. Statement D is wrong, as the conversation is required and the team should not start developing without it. The conversation is an essential part of the 3C concept, as it allows the team to ask questions, share ideas, and collaborate with the product owner to refine the user story and reach a shared understanding. The conversation also helps to identify the dependencies, risks, and assumptions that may affect the implementation of the user story12. References: ISTQB Foundation Level Agile Tester Syllabus1, Section 2.2.1, page 16-17; Effective User Stories - 3C’s and INVEST Guide2, Section The 3 C’s (Card, Conversation, Confirmation) of User Stories.

 Early and frequent feedback is one of the core values of Agile development. It helps the Agile team to deliver features with the highest business value first, to discover and resolve quality problems as soon as possible, to provide information on the team’s productivity and progress, and to ensure that the product meets the customer’s expectations and needs. However, early feedback does not necessarily decrease the amount of time needed for system testing, as system testing is still an important activity in Agile projects to verify the integration and functionality of the whole system. Early feedback may reduce the number of defects found in system testing, but it does not eliminate the need for system testing. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, page 10; ISTQB Agile Tester Sample Exam2, question 11.

As an agile tester, you should work together with the developer, suggesting reasons why the tests are failing. This is an example of the agile principle of collaboration and communication within the team, as well as the agile testing practice of early and frequent feedback. By working together with the developer, you can help to identify and resolve the root causes of the test failures, as well as share your testing knowledge and perspective. This can lead to faster and better quality delivery of the user story, as well as improved team relationships and trust.

Option A is not a good action, because reviewing and improving the design of the user story is not the tester’s responsibility, and it may not address the test failures. Option B is also not a good action, because creating bug reports for blocked tests is not an agile way of handling issues, and it may create unnecessary overhead and waste. Option D is not a good action, because it does not help to unblock the current user story, and it may distract you from the sprint goal and the team’s focus.
