Abstract

U ovome radu prolazi se kroz postupak izgradnje sustava za nadgledanu nadograd-
nju programskih komponenti. Ideja rada je stvoriti sustav koji bi omogućio paralelno
izvršavanje akcija na različitim verzijama aplikacije u svrhu testiranja jedne od verzija
aplikacije koja može biti nadograd̄ena. Kriterij ispravnosti rada nagodrad̄ene verzije
aplikacije svodi se na uspored̄ivanje odgovora na razini aplikacijskog sloja. Ako su
razlike odgovora svedene na faktore koji ovise o slučajnim brojevima, tada je rad nado-
grad̄ene verzije ispravan. Rezultata ovoga rada je proxy sustav koji omogućuje parale-
lan rad dviju različitih verzija aplikacija te usporedbu njihovih odgovora na konkretne
zahtjeve. U radu se nalaze primjeri konkretnog korištenja rada kako bi se pokazala
primjena u praksi.

Abstract (english)

This paper goes through the process of building a system for a controlled update
of software components. The main idea of the process is to create a system that would
allow parallel execution of actions on different versions an application. This way the
upgraded version can be tested for bugs and unwanted errors. The criterion for the
correct operation of the upgraded version of the application comes down to comparing
the responses at the application layer level. If the differences in response are reduced to
factors that depend on random numbers, then the operation of the upgraded version is
correct. The result of this paper is a proxy system that allows the parallel operation of
two different versions of applications and a comparison of their responses. The paper
provides examples of concrete usage of the system to demonstrate its application in
practice.
