Vizualno regresijsko testiranje v DevOps okolju

Kopač, Tilen (author), Rožanc, Igor (mentor)

Cilj diplomske naloge je bil ustvariti orodje, ki v veliki meri pripomore k vzdrževanju vnaprej določenega videza aplikacije že v fazi razvoja, s tem pa tudi k krajšemu ciklu testiranja. Uporabljena je bila metoda vizualnega testiranja, saj to opozarja na morebitno nezaželene spremembe videza. Izvedena je bila večnivojska analiza orodij, ki podpirajo tovrstno testiranje. Najprej je bilo pregledanih veliko število rešitev in narejen ožji izbor. Nato so bile izbrane rešitve ocenjene na podlagi določenih kriterijev. Izbrana je bila najbolje ocenjena. Ta je bila nato umeščena v cevovod opravil, ki se samodejno izvedejo ob spremembi kode. S tem je bila zagotovljena neposredna povratna informacija razvijalcu, ki lahko takoj popravi napake, ki so povzročile nezaželene spremembe videza. To znatno skrajša čas, potreben za njihovo zaznavo in odpravo.

• Title: Visual regression testing in DevOps environment

Abstract

The goal of the thesis was to create a tool which helps maintain the defined appearance of an application in the development phase and, as a result, shortens the testing cycle. For this, visual regression testing was used, as it alerts its user of potentially unwanted changes in appearance of the application under test. A multilevel analysis of the tools, supporting such testing, was performed. First, a high number of solutions were taken into consideration. Tools, forming a selection of the best of them, were then individually rated on the basis of predefined criteria. The solution with the highest rating was chosen. It was then used in a pipeline, which is triggered whenever changes are made to the code of the application. Results of the testing are sent directly to the developer. This allows them to correct the code immediately if necessary. As a result, the time needed to spot and fix unwanted changes is greatly shortened.
