The Grid 2: Blueprint for a New Computing Infrastructure

Metamorphic testing is an approach to both test case generation and test result verification. A central element is a set of metamorphic relations, which are necessary properties of the target function or algorithm in relation to multiple inputs and their expected outputs. Since its first publication, we have witnessed a rapidly increasing body of work examining metamorphic testing from various perspectives, including metamorphic relation identification, test case generation, integration with other software engineering techniques, and the validation and evaluation of software systems. In this article, we review the current research of metamorphic testing and discuss the challenges yet to be addressed. We also present visions for further improvement of metamorphic testing and highlight opportunities for new research.

Metamorphic Testing: A Review of Challenges and Opportunities

As preservers of history and the objects that others leave behind, it is easy to get distracted by a desire for those objects to be “perfect.” We worry about every little tear, stain or blemish, and we want nothing more than to return objects to their "original state." However, so many times those rough spots are part of the item’s history. It is important to understand the difference between the types of condition issues on objects that cause structural issues versus those that are purely cosmetic. Knowing and identifying these differences can help when determining whether or not an item requires conservation or deciding simple factors like the best way to store or exhibit an item.

Gamification is a term that refers to the use of game elements in non-game contexts with the goal of engaging people in a variety of tasks. There is a growing interest in gamification as well as its applications and implications in the field of Education since it provides an alternative to engage and motivate students during the process of learning. Despite this increasing interest, to the best of our knowledge, there are no studies that cover and classify the types of research being published and the most investigated topics in the area. As a first step towards bridging this gap, we carried out a systematic mapping to synthesize an overview of the area. We went through 357 papers on gamification. Among them, 48 were related to education and only 26 met the criteria for inclusion and exclusion of articles defined in this study. These 26 papers were selected and categorized according to their contribution. As a result, we provide an overview of the area. Such an overview suggests that most studies focus on investigating how gamification can be used to motivate students, improve their skills, and maximize learning.

Data privacy when using online systems like Facebook and Amazon has become an increasingly popular topic in the last few years. However, only a little is known about how users and developers perceive privacy and which concrete measures would mitigate their privacy concerns. To investigate privacy requirements, we conducted an online survey with closed and open questions and collected 408 valid responses. Our results show that users often reduce privacy to security, with data sharing and data breaches being their biggest concerns. Users are more concerned about the content of their documents and their personal data such as location than about their interaction data. Unlike users, developers clearly prefer technical measures like data anonymization and think that privacy laws and policies are less effective. We also observed interesting differences between people from different geographies. For example, people from Europe are more concerned about data breaches than people from North America. People from Asia/Pacific and Europe believe that content and metadata are more critical for privacy than people from North America. Our results contribute to developing a user-driven privacy framework that is based on empirical evidence in addition to the legal, technical, and commercial perspectives.

Software testing traditionally receives little attention in early computer science courses. However, we believe that if exposed to testing early, students will develop positive habits for future work. As we have found that students typically are not keen on testing, we propose an engaging and socially-oriented approach to teaching software testing in introductory and intermediate computer science courses. Our proposal leverages the power of gaming utilizing our previously described system HALO. Unlike many previous approaches, we aim to present software testing in disguise - so that students do not recognize (at first) that they are being exposed to software testing. We describe how HALO could be integrated into course assignments as well as the benefits that HALO creates

In recent years, computer games have become increasingly social and collaborative in nature. Massively multiplayer online games, in which a large number of players collaborate with each other to achieve common goals in the game, have become extremely pervasive. By working together towards a common goal, players become more engrossed in the game. In everyday work environments, this sort of engagement would be beneficial, and is often sought out. We propose an approach to software engineering called HALO that builds upon the properties found in popular games, by turning work into a game environment. Our proposed approach can be viewed as a model for a family of prospective games that would support the software development process. Utilizing operant conditioning and flow theory, we create an immersive software development environment conducive to increased productivity. We describe the mechanics of HALO and how it could fit into typical software engineering processes.

Gamification, or the use of game elements in non-game contexts, has become an increasingly popular approach to increasing end-user engagement in many contexts, including employee productivity, sales, recycling, and education. Our preliminary work has shown that gamification can be used to boost student engagement and learning in basic software testing. We seek to expand our gamified software engineering approach to motivate other software engineering best practices. We propose to build a game layer on top of traditional continuous integration technologies to increase student engagement in development, documentation, bug reporting, and test coverage. This poster describes to our approach and presents some early results showing feasability.
