  @conference{beck2021transvis, abstract = {In a microservice system, runtime changes such as failures, deployments, or self-adaptation can trigger the system to transition from one steady state to another, i.e., exhibiting transient behavior. To assess a system's quality, it is imperative that this transient behavior is specified in non-functional requirements and that stakeholders can analyze whether these requirements are met. Yet, there is little support for either specifying transient behavior as a non-functional requirement or analyzing how such a requirement is met in production. We aim to make these two tasks more accessible by utilizing novel human-computer interaction methods. To this end, we developed TransVis, an approach for specifying and analyzing transient behavior based on chatbot interactions and visualizations of the systems' resilience. We examined the effectiveness of our approach by conducting an exploratory expert study on a prototypical implementation. The study revealed that the developed visualizations are effective for specifying and exploring transient behavior. Participants found especially helpful the feature to compare specifications with the actual behavior. However, the integration of a chatbot did not prove effective for our use cases. In conclusion, our approach is capable of supporting stakeholders in the exploration and specification of transient behavior.}, author = {Beck, Samuel and Frank, Sebastian and Hakamian, Alireza and Merino, Leonel and van Hoorn, André}, booktitle = {Proceedings of the 9th IEEE Working Conference on Software Visualization (VISSOFT 2021)}, pages = {65-75}, title = {TransVis: Using Visualizations and Chatbots for Supporting Transient Behavior in Microservice Systems}, year = 2021 }

  @inproceedings{OkanovicBeckMerzZornMerinoVanHoornBeck2020CanAChatbotSupportSoftwareEngineersWithLoadTestingApproachAndExperiences, abstract = {Even though load testing is an established technique to assess load-related quality properties of software systems, it is applied only seldom and with questionable results. Indeed, configuring, executing, and interpreting results of a load test require high effort and expertise. Since chatbots have shown promising results for interactively supporting complex tasks in various domains (including software engineering), we hypothesize that chatbots can provide developers suitable support for load testing. In this paper, we present PerformoBot, our chatbot for configuring and running load tests. In a natural language conversation, PerformoBot guides developers through the process of properly specifying the parameters of a load test, which is then automatically executed by PerformoBot using a state-of-the-art load testing tool. After the execution, PerformoBot provides developers a report that answers the respective concern. We report on results of a user study that involved 47 participants, in which we assessed our tool's acceptance and effectiveness. We found that participants in the study, particularly those with a lower level of expertise in performance engineering, had a mostly positive view of PerformoBot.}, address = {New York, NY, USA}, author = {Okanovic, Dusan and Beck, Samuel and Merz, Lasse and Zorn, Christoph and Merino, Leonel and van Hoorn, Andre and Beck, Fabian}, booktitle = {Proceedings of the ACM/SPEC International Conference on Performance Engineering (ICPE)}, doi = {10.1145/3358960.3375792}, note = {Accepted}, pages = {120-129}, publisher = {Association for Computing Machinery}, series = {ICPE '20}, title = {Can a Chatbot Support Software Engineers with Load Testing?
