The purpose of this thesis is to present a system that has the potential to increase the level of automation of existing electronic testing systems. In order to achieve this, the paper offers certain problems of previous electronic testing systems and descriptions of possible solutions. In addition, the paper proposes a way to implement the system using the features of the existing learning system. The task of this paper is to develop a system for remote testing of knowledge in the Moodle e-learning environment, and in addition, Bloom's taxonomy and its six levels of achievement will presented as the basis of the system for remote testing. The concept of the WbeTS system for testing knowledge and the systems and subsystems required for the realization of the concept will also be presented. Finally, the paper will present a short methodical part with a curriculum modified in such a way that IT classes incorporate the features of WbeTS and Moodle systems so that students can see that the programming concepts they learn are used to solve real problems. In addition, the purpose for this is to build awareness of open source systems. In addition, the methodological part will include preparation for teaching, together with an example of a hierarchy of questions.
