After new capabilities were deployed in a system, issues with preexisting capabilities were reported. Which of the following testing cycles should be used to prevent this issue?

The correct answer is D. Unit testing. The scenario describes a regression issue - new changes breaking existing functionality. While regression testing is the ideal term, Unit testing (D) is the closest answer here because it tests individual components/functions in isolation to verify they still work correctly…

Explanation

The scenario describes a regression issue - new changes breaking existing functionality. While regression testing is the ideal term, Unit testing (D) is the closest answer here because it tests individual components/functions in isolation to verify they still work correctly after changes. It helps catch issues introduced by new code before integration. User acceptance testing (B) validates the full system from a user perspective but is done later. Performance testing (A) and stress testing (C) measure system behavior under load, not functional correctness of existing features.
