Abstract

Fiskalne su blagajne sustav za izdavanje fiskalnog računa. Da bi fiskalna blagajna izdala pojedini račun, ona mora komunicirati sa Poreznom upravom. Izrađen je sustav kojim se ispituje rad fiskalne blagajne. Sustav emulira Poreznu upravu, primajući zahtjeve i šaljući odgovore. Sustav može poslati ispravne, ali i neispravne odgovore na zahtjev fiskalne blagajne. Ispitivanje se provodi promatranjem kako fiskalna blagajna reagira na dane ispravne i neispravne odgovore.
Sustav je implementiran u tri dijela. Prvo, web stranica kojom se korisnik može registrirati u sustav i povezati fiskalnu blagajnu. Drugi dio sustava bavi se povezivanjem web stranice sa “backend” dijelom sustava. Sustav je organiziran kao par klijent, poslužitelj.
Ovaj rad bavi se promatranjem zadnjega dijela sveukupnog sustava. Opisana je tehnologija kojom je sustav izrađen, koraci provedbe samog ispitivanja (provjera, izrada odgovora, izmjena odgovora i digitalno potpisivanje dokumenta) i način izrade pojedinog dodatka. Objašnjen je način provedbe pojedinog ispitnog slučaja. Isto tako, opisan je način izrade i korištenja pojedinog plugina.

Abstract (english)

Fiscal registers are a system for issuing fiscal bills. For a fiscal register to properly issue a bill, it must communicate with the tax administration. A system was made to test the workings of a fiscal register. The system emulates the tax administration, accepting requests and sending responses. The system can send correct, but also incorrect responses for any request. The testing is conducted by observing how the fical register reacts to the given correct and incorrect responses.
The system is implemented in three parts. First, a web site with which a user can register into the system and connect a fiscal register. The second part of the system handles the connection of the web site with the “backend” part of the system. The system is implemented as a client-server pair.
This paper deals with the examination of the last part of the complete system. It describes the tehnology with which the system was made, the steps of conducting the testing (verification, request generation, modification and digital signing of documents) and and how to make a particular plug-in. The method of conducting an individual test case is explained. In addition, the method of making and using an individual plug-in is described.
