Abstract

U ovom radu, opisan je razvoj procedure kreiranja testnih skripti pomoću umjetne inteligencije za testiranje kontrolnih jedinica unutar simulacijskog hardver u petlji (engl. Hardware in the Loop, HiL) okruženja. Jedan od ključnih koraka u procesu HiL testiranja je interpretacija testnih zahtjeva unutar određenog softverskog rješenja. Testni zahtjevi napisani su od strane različitih domenskih eksperata. Upravo zbog toga što je više osoba uključeno u proces pisanja testnih zahtjeva, svaka osoba ima svoj stil pisanja, automatizacija ovog dijela procesa je izazovna. Ideja je razviti metodologiju za kreiranje testnih skripti iz testnih zahtjeva koristeći velike jezične modele (engl. Large Language Model, LLM). Prvo je dan generalni uvod o HiL-ovima i LLM-ovima. Zatim je opisan generalni koncept procesa, koji je podijeljen u dva podprocesa. Prvi se odnosi na interpretaciju testnih zahtjeva u jasne tekstualne korake testa. Drugi se odnosi na generaciju testnih skripti iz jasnih tekstualnih koraka. Prikazana je validacija i analiza rezultata. Na samom kraju dan je zaključak o primjeni modela u realnom industrijskom okruženju i navedena su moguća poboljšanja.

Abstract (english)

This thesis describes the development of a test case design procedure using artificial intelligence methods for testing control units in the Hardware in the Loop (HiL) environment. One of the key steps in the HiL testing process is interpretation of test requirements within a particular software solution. Test requirements are written by various domain experts. Because multiple individuals are involved in the process of writing test requirements, each person has their own writing style, which makes automating this part of the process challenging. The idea is to develop a methodology for test script creation from test requirements using Large Language Models (LLM). First, a general introduction about HiLs and LLMs is given and then a general concept is described. The process is divided into two subprocesses. First one refers to the interpretation of test requirements into clear textual test steps. Second one refers to the generation of test scripts from clear textual test steps. Validation and analysis of the results are presented. At the end of the thesis, a conclusion is given on the application of the methodology in a real industrial environment as well as possible further improvements.
