Final answer:
User acceptance testing is indeed performed by trained end users and is true. It is done to confirm that the software meets their expectations and can handle tasks in real-world scenarios.
Step-by-step explanation:
The statement that user acceptance testing is performed by trained end users to ensure that the system operates as they expect is True. User acceptance testing (UAT) is one of the final stages of the software testing process, during which actual software users test the system to make sure it can handle required tasks in real-world scenarios, according to their requirements. This is a critical phase, as it validates whether the software is ready for production from the user's perspective. Users involved in this phase are usually not part of the development team, ensuring an unbiased assessment of the system functionality. Examples of user acceptance testing include performing common tasks and workflows that the software is designed to handle and verifying that the product behaves as intended.
