“…Furthermore, there is some notion that some NFRs may be realized and guaranteed through certified quality of service guarantees [57], allowing an organization to focus on the core of their business. Third, the utilization of cloud platforms [58], or even simulators [59], allow an organization to easily build otherwise costly environments solely for the purpose of verifying RELIABILITY, AVAILABILITY, PERFORMANCE, and SCALABILITY.…”

Non-functional requirements (NFR), which include performance, availability, and maintainability, are vitally important to overall software quality. However, research has shown NFRs are, in practice, poorly defined and difficult to verify. Continuous software engineering practices, which extend agile practices, emphasize fast paced, automated, and rapid release of software that poses additional challenges to handling NFRs. In this multi-case study we empirically investigated how three organizations, for which NFRs are paramount to their business survival, manage NFRs in their continuous practices. We describe four practices these companies use to manage NFRs, such as offloading NFRs to cloud providers or the use of metrics and continuous monitoring, both of which enable almost real-time feedback on managing the NFRs. However, managing NFRs comes at a cost-as we also identified a number of challenges these organizations face while managing NFRs in their continuous software engineering practices. For example, the organizations in our study were able to realize an NFR by strategically and heavily investing in configuration management and infrastructure as code, in order to offload the responsibility of NFRs; however, this offloading implied potential loss of control. Our discussion and key research implications show the opportunities, trade-offs, and importance of the unique give-and-take relationship between continuous software engineering and NFRs.

“…The paper [28] highlights multi-dimensional hardware design verification using machine learning, where the intersection of functional and non-functional properties of electronic design is analyzed. The works [29,30,31] present solutions for fault tolerance, safety, and reliability in industrial and automotive CPSs.…”

“…To explore NFR testing in CI environments, we found relevant studies in our own recent systematic literature review (SLR) (Yu et al 2020). For example, Rehmann et al (2016); Nouacer et al (2016) and Bougouffa et al (2017) reported three different CI approaches to validate system qualities, such as performance, reliability, and security, in multiple software products. As these studies had a narrower scope focusing only on a particular NFR type, Cannizzo et al (2008); Janus et al (2012) and Chen (2015) investigated the possibility of using a CI approach to evaluate multiple NFR types, such as, system's robustness, performance, and maintainability, but they did not offer detail information about how the NFR testing can be measured.…”

Context Non-functional requirements (NFRs) (also referred to as system qualities) are essential for developing high-quality software. Notwithstanding its importance, NFR testing remains challenging, especially in terms of automation. Compared to manual verification, automated testing shows the potential to improve the efficiency and effectiveness of quality assurance, especially in the context of Continuous Integration (CI). However, studies on how companies manage automated NFR testing through CI are limited. Objective This study examines how automated NFR testing can be enabled and supported using CI environments in software development companies. Method We performed a multi-case study at four companies by conducting 22 semi-structured interviews with industrial practitioners. Results Maintainability, reliability, performance, security and scalability, were found to be evaluated with automated tests in CI environments. Testing practices, quality metrics, and challenges for measuring NFRs were reported. Conclusions This study presents an empirically derived model that shows how data produced by CI environments can be used for evaluation and monitoring of implemented NFR quality. Additionally, the manuscript presents explicit metrics, CI components, tools, and challenges that shall be considered while performing NFR testing in practice.
