Usability testing is a method used to evaluate a product or system's usability and user experience. It involves observing and gathering feedback from real users as they interact with the product or system to identify any usability issues, problems, or areas for improvement.
The primary goal of usability testing is to ensure that the product or system is designed and developed with the end user in mind, making it easy to use, efficient, and satisfying. In addition, by involving real users in the testing process, developers gain valuable insights into how people interact with the product, what difficulties they encounter, and how they perceive the overall user experience.
