SOFTWARE TESTING METHODS AND TECHNIQUES

Razvoj softvera je kompleksan zadatak koji se sastoji od velikog broja različitih faza i koraka. Razvoj podrazumijeva korištenje različitih tehnologija, metoda i tehnika. Kako bi se osigurala isporuka dobrog softvera postoje određene zakonitosti, pravila i definicije koje je potrebno poznavati. Upravo poznavanje i primjena različitih metodologija u razvoju softvera omogućuju pouzdanost i kvalitetu. Kao dio rada bit će opisan životni ciklus razvoja softvera te metode i njihovi principi koji to omogućuju. Jedan od neophodnih koraka u životnom ciklusu razvoja softvera jest testiranje softvera koje je predmet analize ovog rada. Testiranje softvera je postupak pronalaska grešaka s ciljem procjene sposobnosti softvera za rad. Temeljni cilj testiranja softvera je isporuka kvalitetnog i pouzdanog softvera za upotrebu. Ovaj rad ukazuje na važnost provođenja testova te nastoji ukazati na potrebu za testiranjem softvera u njegovom razvoju. U radu je prikazana studija različitih metoda, tehnika, razina i tipova testiranja. Iako je tijekom testiranja ponekad teško pronaći greške neophodnim se pokazalo poznavanje metoda čiji odabir može biti ključ prave kombinacije. Na kraju samog rada provedeno je istraživanje usporedbom prednosti i nedostataka primjene pojedine metode testiranja tijekom razvoja platnog sustava. Istraživanje se zasniva na iskustvenoj metodi koja je omogućila uvid i zaključivanje o stanju procesa testiranja platnog sustava.Software development is a complex task that consists of a large number of different phases and steps. Development involves the use of different technologies, methods and techniques. To ensure the delivery of good software there are certain principles, rules and definitions that need to be known. It is the knowledge and use of different methodologies in software development that enables reliability and quality. The software development life cycle, methods and their principles will be described as part of this paper. One of the necessary steps in the software development life cycle is the software testing that is the subject of the analysis of this paper. Software testing is process of evaluating the software with intention to find out error in it. The basic goal of software testing is to deliver quality and reliable software for use. This paper shows the importance of software testing in software development. The paper presents a study of different methods, techniques, levels and types of testing. Although is sometimes difficult to find errors during test, it is proved as necessary to know different methods and selection of right method can be key of successful combination. At the end of the paper, a research was conducted comparing the advantages and disadvantages of applying individual testing methods during the development of the payment system. The research is based on experiential method that provided insight about state of payment system testing process
