What term describes a person's perceptions and responses resulting from the use or anticipated use of a software product?

User experience refers to the overall feelings, attitudes, and perceptions a person has while interacting with a software product, whether during actual usage or anticipating its use. This encompasses all aspects of the end-user's interaction with the product, including usability, accessibility, performance, and satisfaction. Understanding user experience is crucial in the development and testing phases, as it ensures that the software meets the needs and expectations of its users.

This contrasts with user interface, which specifically refers to the visual elements and controls through which users interact with the software, rather than the feelings and perceptions derived from that interaction. A user story is a brief description of a feature from the perspective of the end user and is part of agile methodologies focusing on customer value. White-box testing relates to testing internal structures or workings of an application rather than the user's experience of it.
