Exam CTFL-AT Topic 2 Question 53 Discussion

Explanation
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.
