The goal of this testing category is to ensure that a user can operate your app effectively without requiring complex inputs or trial-and-error. It should always be clear what a button or link will do when a user selects it, and the size of the button or link should afford enough space for the user so that they can easily select it without accidentally selecting something else. A user also shouldn’t have to move their device in a certain way to use your app as they may have their device mounted or they may not be capable of performing certain motions.
