CTAL-ATT Exam Dumps : Certified Tester Advanced Level Agile Technical Tester

Given the high risk level and the need for a regression-averse strategy due to potential changes in screen design and functionality, the best test approach would involve a strong emphasis on test automation to ensure that new changes do not break existing functionality. Exploratory testing is neutral as it can be useful but is not the primary focus. Manual black-box testing is recommended to verify that the system meets the requirements from an end-user perspective.

Therefore, the option that aligns with these needs is:

Test Automation: ♦+ (highly recommended)

Exploratory Testing: o (neutral/optional)

(manual) Black-box testing: ♦♦ (recommended)

This corresponds to Option 1, which suggests a heavy reliance on automated testing to manage regression risks efficiently, while still incorporating manual black-box testing to cover user experience aspects.

References = The ISTQB Advanced Level Agile Technical Tester documents and training resources emphasize the importance of test automation in Agile projects, especially when dealing with high-risk levels and the need for regression testing1. Additionally, the resources available at Software Testing Help provide insights into Agile testing strategies and best practices that support such an approach2.

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.

The appropriate test charter for the user story provided should focus on the customer’s experience and the functionality described in the story. Option C is the most suitable because it covers the entire process from the customer’s perspective: logging in, purchasing an item, receiving information about the requirement for free shipping, adding more items, and then verifying that the delivery is free upon checkout. This test charter effectively tests the acceptance criteria of the user story by ensuring that the system provides the necessary information and applies the free shipping offer correctly when the conditions are met.

References = The ISTQB Advanced Level Agile Technical Tester syllabus outlines the importance of creating test charters that align with user stories and epics using requirements engineering techniques. It emphasizes the need for test charters to be comprehensive and to evaluate the acceptance criteria effectively123.
