CTAL-TTA Exam Dumps : Certified Tester Advanced Level Technical Test Analyst

Story Mapping is an effective requirements engineering technique used in Agile environments to provide a visual representation of the system. It helps in understanding the 'overall' story and functional flow by mapping user stories along a timeline or process steps, laying them out in a two-dimensional structure that represents the product backlog. This technique is particularly useful for visualizing the scope of large features or entire systems, making it easier to plan releases and improve understanding among the team .

Analysis:

The significant non-functional defects recorded for the BestForFood system indicate issues that could be mitigated by appropriate non-functional testing strategies:

Portability Testing:

Ensures that the application can operate in different environments without issues. This could have addressed the defect related to the layout and navigation consistency across different websites (Defect A).

Compatibility Testing:

Ensures that the application works well with other systems and environments. This could have helped in preventing the performance issues noticed in the BestForPensions and BestForMortgages websites after the deployment of BestForFood (Defect B).

Explanation of Incorrect Options:

C. The time taken to diagnose, repair and re-test production defects: This is more related to maintainability and operational processes.

D. BestForFood performance impacted by data growth: This is better addressed through performance and scalability testing.

E. Installation time exceeding agreed timescales: This is related to deployment and operational efficiency.

References:

The ISTQB CTAL-TTA syllabus and standard non-functional testing practices emphasize the importance of portability and compatibility testing for ensuring smooth operation across different environments and systems.

Statements about Maintainability Testing:

A. It should start as soon as the draft design documents are available for review.

True. Maintainability testing can begin early in the development lifecycle, starting with reviews of design documents to ensure that maintainability concerns are addressed from the outset.

B. An application can be considered maintainable when static analysis and code review defects have been fixed.

False. While fixing defects identified by static analysis and code reviews improves maintainability, other factors such as documentation, ease of making changes, and regression testing must also be considered.

C. It tests the regression impact of software or environmental changes to an operational system.

False. This describes regression testing more than maintainability testing, which focuses on the ease of modifying the system and maintaining its performance.

D. It can be performed during Operational Acceptance Testing by multiple departments.

True. Maintainability testing can be part of operational acceptance testing (OAT), where different departments ensure that the system can be maintained and operated effectively.

E. It can be performed during User Acceptance Testing to ensure business processes can be maintained.

False. User acceptance testing (UAT) focuses on verifying that the system meets business requirements and user needs, not specifically on maintainability.

Correct Answer:

B. a and d
