ISTQB CT-TAE – Certified Tester Test Automation Engineer — Question 25

Your organisation has successfully implemented a Test Automaton Solution (TAS) for a new project which has since been delivered into production via a number of sprints. A series of maintenance releases are now planned.
Some improvements were made to the Test Automation Architecture (TAA) as a result of feedback from the early sprints. The TAA improvements affected the TA, and the TAS was changed for the final sprint.
The new version of the TAS was generally well received but some performance and usability issues were encountered with the TAS which have yet to be addressed.
The test automation engineers supporting the maintenance releases must decide whether to use the enhanced TAS or the version that was used successfully for previous sprints.
What is the BEST action to take next?

Answer options

• A. Perform an analysis of risks versus benefits for the enhanced TAS and then decide which version to use.
• B. Use the previous version because this was proven to work. It will be too risky to use the new version, with unresolved issues, for a live system.
• C. Use the new version because, despite some issues, it works, and the live system should not be tested using a different TAS.
• D. Use the new version of the TAS for the first maintenance release on a trial basis. If issues are encountered, switch to the previous version for later releases until the issues are resolved.

Correct answer: A

Explanation

The best action is to perform an analysis of risks versus benefits for the enhanced TAS because it allows for a comprehensive evaluation of the potential impact of using the new version with known issues. While using the previous version is safer, it may prevent the team from leveraging improvements made. Adopting the new version outright or on a trial basis without understanding the risks could lead to problems in the live environment.
