In the issue of user testing in cartography we have to consider at least three main points of view - user and his skills, test situation and task as itself (i.e. what is asked to be done). Based on these three basic parameters there is established test situation, in which we focus on the participants (or user) performance when he or she interacts with specific given task. The aim of the presentation was to introduce specifics of user interfaces in cartography testing and there were also presented specific examples from practice.
