You are not your user, so the only way to know whether a design works is to watch real people try to use it. Usability testing does exactly that: you give participants realistic tasks, observe where they succeed or struggle, and learn why. Even a handful of sessions will reveal problems you would never spot on your own.
You'll learn the basics of usability testing, how to plan a study with realistic tasks, how to moderate sessions without leading the participant, and how to analyse your findings and prioritise what to fix first.
