ISTQB ISTQB-CTAL-TA Dumps Questions Answers

The technique that is most likely to support the required functional correctness testing is state transition testing. State transition testing is a technique that tests the behavior of a system or component based on its states and transitions between them. This technique is suitable for testing a system that has different modes or states depending on the input values or events, such as a car navigation system.

The comment that should be made about the Supercar specification is that boundaries for stock levels are ambiguous. The specification states that the site will allow an order to be processed if at least one of the chosen vehicle configurations is in stock, but it does not define what constitutes “in stock” or how many units are available for each configuration. This makes the specification unclear and inconsistent, as it does not provide enough information for testing or implementation.

Comprehensive and Detailed in Depth Explanation:

Portability testing verifies that software can be transferred from one environment to another with minimal effort. It checks for installation, adaptation, and replacement issues.

a) Insufficient, unclear installation or de-installation instructions:This directly relates to portability because improper installation procedures can affect moving the software to different environments.

e) The stock control barcodes cannot be read by the replaced barcode scanner:This issue is associated with compatibility and adaptability between devices, which is crucial in portability testing.

Optionsb) and d)relate to usability and performance testing, not portability.

Optionc)relates to security or access control testing.

Therefore, the correct answer isA (a, e).
