“…In paper "Exploring the Context of Use for Voice User Interfaces: Toward Context-dependent UX Quality Testing," 2 Klein et al perform a comprehensive study on how the voice user interface (VUI) systems are used. The results provide many useful insights on how modern applications user interfaces should be designed beyond the traditional command line and graphical interfaces.…”

It is with a great pleasure that we, as the Guest Editors, can finally present the Special Issue on "Software Quality for Modern Systems" for the Journal of Software: Evolution and Process.Software pervasiveness in modern systems strongly affects both industry and digital society. As a notable recent example, the proliferation of artificial intelligence (AI) technologies is continuously leading to emerging needs and expectations from both software producers and consumers.At the same time, infrastructures, software components, and applications aim to hide their increasing complexity in order to appear more human-centric. However, the potential risk from design errors, poor integration, and time-consuming engineering phases can result in unreliable solutions that can barely meet their intended objectives. In this context, software engineering processes keep demanding for the investigation of novel and further refined approaches to software quality assurance (SQA).Software testing automation is a discipline that has produced noteworthy research in the last decades. The search for solutions to automatically test any concept of software is critical, and it encompasses several areas. These include generating test cases, test oracles, and test doubles (e.g., dummies, stubs, mocks, and fakes); defining test selection and prioritization criteria; engineering infrastructures governing; and optimizing the execution of testing sessions locally or remotely in the cloud.In this sense, we launched this special issue in order to explore current research methods, empirical evaluations, or industrial case studies involving software test automation for modern software systems such as AI solutions or applications, mobile applications, adaptive systems, or distributed and cloud platforms. Accordingly, we crafted a dedicated call for papers, inviting both the research and industrial communities to submit research papers in test automation focusing on improving various software quality attributes.

Voice user interface (VUI) systems, such as Alexa, Siri, and Google Assistant, are popular and widely available. Still, challenges such as privacy and the ability to have a dialog remain. In the latter example, the user expects a human‐like conversation, that is, that the VUI understands the dialog and its context. However, this VUI feature of context‐aware interaction is rather error prone. For this reason, we intend to explore the VUI context of use and its impact on interaction, that is, relevant user experience (UX). We see a demand for context‐dependent UX measurement because analyzing the context of use and UX assessment are both critical human‐centered design (HCD) methods. Therefore, we examine the VUI context of use by asking users about how, where, and for what they use VUIs, as well as their UX and improvement proposals. We interviewed people with disabilities who rely on VUIs and people without disabilities who use VUIs for convenience or fun. We identified VUI context‐of‐use categories and factors and explored their impacts on relevant UX qualities. Our result is a matrix containing these elements; thus, it provides an overview of the contextual UX of our target group's VUI interaction. We intend to develop a VUI context‐of‐use conceptual structure in the future based on this matrix, which is needed to create an automated context‐dependent UX measurement recommendation tool for VUIs. This conceptual structure could also be useful for automated UX testing in the context of VUI.

ContextPrioritizing usability in software development is vital to ensure a positive user experience and efficient performance. Failing to do so can result in negative consequences such as increased costs, damage to reputation, and loss of trust. Usability should be considered throughout the entire software development life cycle (SDLC), not just as an afterthought. Accordingly, adopting and integrating usability practices is crucial but can be complex. Thus, organizations must assess their readiness to start and improve usability initiatives. In this context, software organizations can benefit from using a usability readiness model to enhance integration and assist practitioners in systematically and structurally applying usability practices.ObjectiveWe propose a readiness model for usable software development (RMUSD). This model allows organizations to assess their readiness to create usable software, leading to improved user experience and better usability methods throughout the SDLC.MethodTo develop the RMUSD, we conducted a systematic mapping study that gathered 238 relevant studies in the usability engineering domain. From these studies, we synthesized 50 best usability practices that form the foundation of the RMUSD. We also drew inspiration from existing software engineering readiness and usability maturity models.ResultsThe RMUSD is built at five levels, each with various aspects to consider, such as related usability practices, implications, organizational characteristics, and success factors for moving up to the next level. The model was evaluated through two real‐world case studies and eight experts.ConclusionThe evaluation results reveal that the suggested RMUSD is practical in determining the organization's readiness to develop usable software.
