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

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.

A deterministic unit test is one that produces the same results every time it is run under the same conditions. This characteristic is crucial for unit tests because it ensures that the tests are reliable and that their results are repeatable. Deterministic tests help in identifying when a change in the codebase has introduced a defect, as any variation in the test outcome can be attributed to the change rather than an unpredictable test behavior12.

References = The ISTQB Advanced Level Agile Technical Tester syllabus and study resources emphasize the importance of deterministic behavior in unit tests as part of ensuring test reliability and effectiveness34.

Definition of "Atomic" in Unit Testing:

An atomic test focuses on a single, isolated piece of functionality.

This ensures clarity and simplicity in verifying the behavior of that specific functionality.

Analyzing the Options:

A: Describes a deterministic test, not an atomic one.

B: Atomic tests do not verify all details but rather focus on a specific area.

D: Speed is a desirable characteristic but does not define atomicity.

C: Testing only the targeted functionality aligns with the definition of atomicity.
