Publikation Interactive use-case generation tool for functional REST API testing(Hochschule für Technik FHNW, 18.08.2023) Volken, Jonas; Leu, Benjamin; Kropp, Martin; Affolter, Fabian; Tesitifi GmbHSoftware is an integral part of any business, which makes the significance of high-quality software in today’s digital age undeniable. However, despite the advancements in software testing, challenges persist in efficiently planning, generating, and executing test cases, particularly for REST API-based applications. This project addresses the issue by developing a sequence generator tool that enables testers to effortlessly create and execute sequences of requests, streamlining the creation of comprehensive test scenarios. By simplifying the process of connecting response values to subsequent request values, the software seeks to maximize test coverage, improve test quality, and enable testers to focus more on software quality enhancement than the efforts of test construction. The client for this project is Testifi GmbH, a company dedicated to enhancing software delivery processes through DevOps integrations and AI-automated quality assurance solutions. The main focus of the project was to find out if the test quality increased by using the sequence generator tool due to more edge cases and more complex scenarios being tested compared to manual API testing, as well as showing if the efficiency improvement can be measured in reduced amount of time necessary for creation sequences. To answer these questions and develop an application that offers value for Testifi GmbH, a literature review was conducted on the subjects of basic user interface design and user experience concepts for advanced users. Based on the findings, the user interface of the application was outlined and the software implemented. During development and with the finished product, multiple sets of user tests were conducted with users experienced in working with APIs, to improve the design and software during development, and to gain insights about the effectiveness of the final product. Those tests showed that the main goals of the project could be reached by demonstrating a considerable amount of time saved by using the application, while also outperforming manual testing methods in efficiency and ease of use. Key features like the linking of response values to subsequent request values and the suggestion of such links based on Testifi’s Pulse Artificial intelligence (AI) as well as previously created sequences were well received by testers and customer. The literature review also proved to be very valuable as users praised the straightforward design, while never missing any important data. When Testifi GmbH integrates the end product in their pulse workflow, its ability to create sequences easily and intuitively as well as the potential of the additional link suggestions created by the tool to be used in improving the Pulse AI will be indispensable.11 - Studentische ArbeitPublikation Benefits of card walls in agile software development. A systematic literature review(Springer, 2022) Sallin, Marc; Kropp, Martin; Stray, Viktoria; Stol, Klaas-Jan; Paasivaara, Maria; Kruchten, PhilippeCard walls are often used to visualize various aspects of the software development process. They are an essential and widespread agile practice. Despite the drawback of physical card walls, its digital version is often not considered a sufficient alternative. This paper aims to find the reason for this and suggests how to evolve digital card walls into a viable alternative. We conducted a systematic literature review and analyzed twenty-two studies. We identified which desirable effects agile teams get from card wall usage and derived a set of properties a card wall needs to achieve those effects. Furthermore, we suggested a typology of card walls to compare the benefits and challenges among them.04B - Beitrag KonferenzschriftPublikation Waste self-reporting for software development productivity improvement(Springer, 2023) Sallin, Marc; Kropp, Martin; Anslow, Craig; Biddle, Robert; Stettina, Christoph J.; Garbajosa, Juan; Kruchten, PhilippeLittle research has been done on enabling software development teams to self-report waste to assist in productivity improvement. This study created a waste categorization and survey for teams to identify and quantify wasteful activities. Developers from a Swiss company used the survey for three weeks. Participants found the survey helpful for identifying waste but there was little evidence that self-reported waste correlated with improved performance.04B - Beitrag KonferenzschriftPublikation Visualizing progress tracking for software teams on large collaborative touch displays(IEEE, 2020) Scott-Hill, Brandon; Anslow, Craig; Ferreira, Jennifer; Kropp, Martin; Mateescu, Magdalena; Meier, Andreas04B - Beitrag KonferenzschriftPublikation Maintenance and evolution of large scale software systems – Business, dev & ops challenges(10.02.2023) Rüegger, Janick; Kropp, MartinEven in the time of agile software development and devOps, maintenance and evolution of large-scale software systems remain challenging. This is not only caused by technical debt, but is heavily caused by lost knowledge, high complexity of micro-service architectures, difficult requirements management, not available documentation, and the complexity of communication among and coordination of the many stakeholders. In our session we will talk about the challenges we identified in our study and present new approaches to address these challenges.06 - PräsentationPublikation Satisfaction and its correlates in agile software development(Elsevier, 2020) Kropp, Martin; Meier, Andreas; Anslow, Craig; Biddle, Robert01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Measuring Software Delivery Performance Using the Four Key Metrics of DevOps(Springer, 2021) Sallin, Marc; Kropp, Martin; Anslow, Craig; Quilty, James W.; Meier, Andreas; Gregory, Peggy; Lassenius, Casper; Wang, Xiaofeng; Kruchten, PhilippeThe Four Key Metrics of DevOps have become very popular for measuring IT-performance and DevOps adoption. However, the measurement of the four metrics deployment frequency, lead time for change, time to restore service and change failure rate is often done manually and through surveys - with only few data points. In this work we evaluated how the Four Key Metrics can be measured automatically and developed a prototype for the automatic measurement of the Four Key Metrics. We then evaluated if the measurement is valuable for practitioners in a company. The analysis shows that the chosen measurement approach is both suitable and the results valuable for the team with respect to measuring and improving the software delivery performance.04B - Beitrag KonferenzschriftPublikation Satisfaction and its correlates in agile software development(Elsevier, 06/2020) Kropp, Martin; Meier, Andreas; Anslow, Craig; Biddle, RobertIn this paper we address the topic of software development team members satisfaction with their development process. We present an in-depth analysis of the results of a nationwide survey about software development in Switzerland. We wanted to find out if satisfaction relates to the applied development method, and to the use of various practices, and impacts on business, team and software issues. We found that higher satisfaction is reported more by those using Agile development than with plan-driven processes. We explored the different perspectives of developers and those with a management role and found a high consistency of satisfaction between Agile developers and Agile management, and differences with those using working plan-driven methods. We found that certain practices and impacts have high correlations to satisfaction, and that collaborative processes are closely related to satisfaction. We then explored the relationship between satisfaction and various other perspectives. Our results in this analysis are principally descriptive, but we think they can be a relevant contribution to understand the challenges for everyone involved in Agile development.01A - Beitrag in wissenschaftlicher Zeitschrift
