Correct answer & explanation
✓
User acceptance testing
User acceptance testing (UAT) is the final phase of testing where actual end-users validate the system against real-world business requirements and workflows. It confirms that the system meets the agreed-upon business needs, functional specifications, and operational criteria before production deployment. Unlike technical testing phases, UAT focuses on business process alignment and user satisfaction.
