On the emergence of testing strategies
A socio-technical grounded theory
Software testing crucial for ensuring software quality, yet developers’ engagement with it varies widely. Identifying the technical, organizational and social factors that lead to differences in engagement is required to remove barriers and utilize enablers for testing. While much research emphasizes the usefulness of software testing approaches and technical solutions, less is known about why developers do (not) test. This study investigates the first-hand experience of developers with software testing. The study illuminates how developers’ opinions about testing and their testing behavior changes. Through analysis of personal evolutions of practice, we explore when and why testing is used. Employing socio-technical grounded theory (STGT), we construct a theory by systematically analyzing data from 19 in-depth, semi-structured interviews with software developers. Allowing interviewees to reflect on how and why they approach software testing, we explore perspectives that are rooted in their contextual experiences. We develop eleven categories of circumstances that act as conditions for the application and adaptation of testing practices and introduce three concepts that we then use to present a theory of emerging testing strategies (ETS) that explains why developers do (not) use testing practices. This study reveals a new perspective on the connection between testing artifacts and collective reflection of practitioners, and it embraces testing as an experience in which human- and social aspects are entangled with organizational and technical circumstances.

The qualitative factor in software testing
A systematic mapping study of qualitative methods
Software testing research has provided metrics on efficiency, error rates, and insights into the effectiveness of testing methodologies and tools. However, these tell only a part of the story. The qualitative dimension, which studies experiences, perceptions, and decision-making processes is crucial, but less prevalent in literature. This study aims to systematically map qualitative research in software testing to consolidate and categorize the methodologies used in qualitative testing research, highlight their importance, and identify patterns, gaps, and future directions. We conducted a systematic mapping study, identifying and analyzing 102 primary studies from 2003 to 2023. We categorized the studies according to research strategies, data collection, and data analysis methods. We identified case studies and grounded theory as the most prevalent research strategies. Researchers primarily used semi-structured interviews and thematic analysis to understand how practitioners work and gather stakeholder perspectives. The subject areas most covered by qualitative studies included software testing processes and risks, and test automation. Areas such as test oracles, and machine learning were underrepresented. We also assessed the quality of reporting and the methodological rigor, emphasizing the challenges and limitations identified during the process. Through this study, we provide a comprehensive overview of qualitative research practices in software testing, revealing trends, gaps, and methodological insights.

Sentiment overflow in the testing stack
Analyzing software testing posts on Stack Overflow
Software testing is an integral part of modern software engineering practice. Past research has not only underlined its significance, but also revealed its multi-faceted nature. The practice of software testing and its adoption is influenced by many factors that go beyond tools or technology. This paper sets out to investigate the context of software testing from the practitioners’ point of view by mining and analyzing sentimental posts on the widely used question and answer website Stack Overflow. By qualitatively analyzing sentimental expressions of practitioners, which we extract from the Stack Overflow dataset using sentiment analysis tools, we discern factors that help us to better understand the lived experience of software engineers with regards to software testing. Grounded in the data that we have analyzed, we argue that sentiments like insecurity, despair and aspiration, have an impact on practitioners’ attitude towards testing. We suggest that they are connected to concrete factors like the level of complexity of projects in which software testing is practiced.
