“…The process of selecting open-source projects consists of a systematized search, on Github, using the keywords "virtual reality" and "VR". With the objective of drawing a more specific profile, the search focused only on projects developed for the Unity platform, since it has emerged as the most popular VR development platform due to its extensive documentation [Ghrairi et al, 2018].…”

“…Ghrairi et al [Ghrairi et al, 2018] made an exploratory study on Github and Stack Overflow in order to investigate which are the most popular languages and engines used in VR projects. According to their results, the most popular language for VR development is C#, and Unity is the most used game engine during VR application development.…”

“…Unlike our work, the paper does not analyze the content of the cataloged material in detail, and is limited to studying the growing trends, development involvement, favorite topics, and frequent file changes in these projects. Ghrairi et al [Ghrairi et al, 2018] conducted a study on the exploratory analysis of Github projects and questions extracted from StackOverflow, analyzing it from a software engineering point of view. The study demonstrates the current state of practice regarding the development of open-source VR applications, highlighting mainly the most used platforms and technologies.…”

Software testing is a critical activity to ensure that software complies with its specification. However, current software testing activities tend not to be completely effective when applied in specific software domains in Virtual Reality (VR) that has several new types of features such as images, sounds, videos, and differentiated interaction, which can become sources of new kinds of faults. This paper presents an overview of the main VR characteristics that can have an impact on verification, validation, and testing (VV&T). Furthermore, it analyzes some of the most successful VR open-source projects to draw a picture concerning the danger of the lack of software testing activities. We compared the current state of software testing practice in open-source VR projects and evaluate how the lack of testing can be damaging to the development of a product. We assessed the incidence of code smells and verified how such projects behave concerning the tendency to present faults. We also perform the same analyses on projects that are not VR related to have a better understanding of these results. The results showed that the practice of software testing is not yet widespread in the development of VR applications. It was also found that there is a high incidence of code smells in VR projects. Analyzing Non-VR projects we noticed that classes that have test cases tend to produce fewer smells compared to classes that were not tested. Regarding fault-proneness analysis, we used an unsupervised approach to VR and Non-VR projects. Results showed that about 12.2% of the classes analyzed in VR projects are fault-prone, while Non-VR projects presented a lower fault-proneness rate (8.9%). Regarding the application of software testing techniques on VR projects, it was observed that only a small number of projects are concerned about developing test cases for VR projects, perhaps because we still do not have the necessary tools to help in this direction. Concerning smells, we concluded that there is a high incidence in VR projects, especially regarding implementing smells and this high incidence can have a significant influence on faults. Finally, the study related to fault proneness pointed out that the lack of software testing activity is a significant risk to the success of the projects.

The increasing availability and diversity of virtual reality (VR) applications highlighted the importance of their usability. Function-oriented VR applications posed new challenges that are not well studied in the literature. Moreover, user feedback becomes readily available thanks to modern software engineering tools, such as app stores and open source platforms. Using Firefox Reality as a case study, we explored the major types of VR usability issues raised in these platforms. We found that 77% of usability feedbacks can be mapped to Nielsen's heuristics while few were mappable to VR-specific heuristics. This result indicates that Nielsen's heuristics could potentially help developers address the usability of this VR application in its early development stage. This work paves the road for exploring tools leveraging the community effort to promote the usability of function-oriented VR applications.
