Improving testing abilities of a programming tutoring system

Testing of learner´s knowledge is demanding functionality of the e-learning systems. Multiple choice questions are suitable and easy to implement feature for testing the knowledge in systems for learning social studies. However, these questions are not suitable for systems for learning the basics of programming problems where solutions are not exact. In previous work we have presented the basic functionalities of the Protus system that implements Java programming course for beginners. Testing knowledge in this system is implemented through various tests with numerous multiple-choice questions. The aim of this paper is to present integration of the existing automatic assessment tool named Testovid within Protus system in order to achieve advanced testing functionalities in solving programming tasks.
