The user story provided is quite broad and encompasses multiple functionalities, which suggests it is more of an epic than a small, deliverable user story. The INVEST criteria for Agile user stories require that stories be Independent, Negotiable, Valuable, Estimable, Small, and Testable. In this case:

Independent: This user story seems to have dependencies, as the ability to print the bill, view it in different currencies, and flag items are likely interconnected functionalities.

Negotiable: The user story provides specific solutions rather than outlining the problem to solve, which limits the negotiation on how to implement the solutions.

Valuable: The story does provide value to the hotel guest, which is clear.

Estimable: With the information provided, the development team can likely estimate the effort required.

Small: The story is not small; it covers multiple features that probably cannot be delivered in a single iteration.

Testable: The acceptance criteria are testable, although they are quite detailed and prescriptive.

References = The explanation is based on the INVEST criteria as described in Agile methodologies1234. The criteria are used to assess the quality of a user story, ensuring it is well-defined and suitable for Agile development practices. The user story in question does not fully meet the ‘Negotiable’ and ‘Small’ criteria, which is essential for maintaining flexibility and delivering incremental value in Agile projects.

Regression-Averse Test Approach:This approach minimizes risks by ensuring tests remain relevant and effective over time. The key focus is maintaining and enhancing the regression suite to reflect changes in the software.

Continuous Improvement of Tests:Keeping tests updated ensures the test suite is reliable and maintains high coverage. This involves adding tests for new features, removing obsolete tests, and refining existing ones.

Conclusion:Option D is correct because it aligns with the goals of regression-averse approaches.

 The correct use of Behavior-Driven Development (BDD) to design test scenarios involves specifying the behavior in a given-when-then format. This format helps to clarify the conditions under which a particular outcome should occur. Option A follows this structure correctly:

Given that the shopper scans their card (the precondition),

When they checkout (the action),

Then they should receive all the quantity discounts for everything they have purchased (the expected outcome).

This scenario clearly outlines the behavior of the system in response to the user’s actions, which is central to BDD.

References = The ISTQB Advanced Level Agile Technical Tester syllabus emphasizes the importance of creating testable acceptance criteria for a given user story using requirements engineering and test techniques, which include the application of BDD in the context of a given user story12.
