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

When purchasing a simulator for performance testing, considerations should include:

Time to test the tool – How long it will take to validate the simulator itself.

Cost of hiring specialists – The financial aspect of requiring specialized knowledge to operate or customize the simulator.

Method and time to upgrade and retest the tool as the software changes – How the simulator can be kept up-to-date with the software it is meant to simulate and the effort involved in retesting it after updates.

These points focus on practical and economic aspects of using a simulator in testing environments.

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.

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.

General knowledge on non-functional testing practices.

A Technical Test Analyst during a product risk analysis would consider the complexity of new technology as a generic risk factor. Complex new technology can introduce uncertainties and potential issues that may not be well-understood, which can increase the risk of defects. Frequency of use, visibility of failure, and high change rate of business requirements are also valid considerations, but they are more specific to particular scenarios or aspects of the product rather than the generic technological complexity which is always a concern regardless of the context.
