Comprehensive and Detailed In-Depth Explanation:Statement coverage strategyprioritizestest cases with higher statement coverage first, whileresolving dependenciesbefore execution.

TC60 (7%)has thehighest coveragebutdepends on REQ 1, so it should be executedafter its dependency is covered.

TC80 (6%)depends onREQ 2, so it should be prioritizedafter TC40 (REQ 2).

TC40 (5%)andTC90 (5%)should be executed early.

Lower coverage test cases (TC10, TC70, TC30, TC20) should come last.

Thus, the correct order is{TC 60; TC 80; TC 40; TC 90; TC 50; TC 10; TC 70; TC 30; TC 20} (D).

Comprehensive and Detailed In-Depth Explanation:Business, development, and testing (C)are the three key perspectives inagile user story refinement:

Business (Product Owner, Stakeholders)– Ensures the story aligns with user needs and business goals.

Development (Developers)– Provides insights on feasibility and technical constraints.

Testing (Testers, QA)– Ensures testability, acceptance criteria, and risk identification.

(A) is incorrectbecause the product owner is part of business stakeholders.

(B) is incorrectbecause architecture is part of development, but not the primary driver of user stories.

(D) is incorrectbecauseacceptance testing is a process, not a stakeholder group.

Across-functional team collaborationensureswell-defined, testable, and feasibleuser stories.

Looking for defects in a system does not require ignoring system details, but rather paying attention to them and understanding how they affect the system’s quality, functionality, and usability. Ignoring system details could lead to missing important defects or testing irrelevant aspects of the system.

Identifying defects may be perceived as criticism against product, especially by the developers or stakeholders who are invested in the product’s success. However, identifying defects is not meant to be a personal attack, but rather a constructive feedback that helps to improve the product and ensure its alignment with the requirements and expectations of the users and clients.

Looking for defects in system requires professional pessimism and curiosity, as testers need to anticipate and explore the possible ways that the system could fail, malfunction, or behave unexpectedly. Professional pessimism means being skeptical and critical of the system’s quality and reliability, while curiosity means being eager and interested in finding out the root causes and consequences of the defects.

Testing is often seen as a destructive activity instead of constructive activity, as it involves finding and reporting the flaws and weaknesses of the system, rather than creating or enhancing it. However, testing is actually a constructive activity, as it contributes to the system’s improvement, verification, validation, and optimization, and ultimately to the delivery of a high-quality product that meets the needs and expectations of the users and clients.
