How is usability testing best defined?

Usability testing is best defined as evaluating how easy and user-friendly an application is. This type of testing focuses on the end user's interaction with the software to ensure that it provides a positive experience. During usability testing, real users perform specific tasks while observers monitor their behavior and gather feedback. This process helps identify areas where users struggle, which can inform improvements to enhance overall user satisfaction and efficiency.

The critical aspect of usability testing lies in assessing various elements, such as navigability, layout, functionality, and overall user experience. By focusing on how users engage with an application, usability testing aims to create products that are not only functional but also intuitive and enjoyable to use.
