Sampling is a promising approach to reduce the testing effort for product-based systems by finding a small but still representative subset (i.e., a sample) of all configurations for testing. The quality of a generated sample wrt. evaluation criteria such as run time of sample generation, feature coverage, sample size, and sampling stability depends on the subject systems and the sampling algorithm. Choosing the right sampling algorithm for practical applications is challenging because each sampling algorithm fulfills the evaluation criteria to a different degree. Researchers keep developing new sampling algorithms with improved performance or unique properties to satisfy application-specific requirements. Comparing sampling algorithms is therefore a necessary task for researchers. However, this task needs a lot of effort because of missing accessibility of existing algorithm implementations and benchmarks. Our platform AutoSMP eases practitioners and researchers lifes by automatically executing sampling algorithms on predefined benchmarks and evaluating the sampling results wrt. specific user requirements. In this paper, we introduce the open-source application of AutoSMP and a set of predefined benchmarks as well as a set of T-wise sampling algorithms as examples.","PeriodicalId":416819,"journal":{"name":"Proceedings of the 25th ACM International Systems and Software Product Line Conference - Volume B","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124429231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MODEVAR initiative tries to establish a common textual feature modelling language that can be used by different communities and can allow information sharing. Feature model related researches use different models for different purposes such as analysis, sampling, testing, debugging, teaching, etc. Those models are shared in private repositories and there is a risk that all that knowledge is spread across different platforms which hinder collaboration and knowledge reuse. In this paper, we propose a first working version of a new feature model repository that allows to centralise the knowledge generated in the community together with advanced capabilities such as DOI generation, an API, analysis reports, among others. Our solution is a front end interface that uses the popular open science repository Zenodo as an end point to materialise the storage of all the information. Zenodo is enhanced with characteristics that facilitate the management of the models. The idea of our repository is to provide existing but also new features that are not present in other repositories (e.g., SPLOT). We propose to populate our repository with all the existing models of many sources including SPLOT.","PeriodicalId":416819,"journal":{"name":"Proceedings of the 25th ACM International Systems and Software Product Line Conference - Volume B","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121390685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DSPL approaches make decisions supported by performance models, which capture system features' contribution to one or more optimization goals. Combining performance models with Multi-Objectives Evolutionary Algorithms (MOEAs) as decision-making mechanisms is common in DSPLs. However, MOEAs algorithms start solving the optimization problem from a randomly selected population, not finding good configurations fast enough after a context change, requiring too many resources so scarce in CPSs. Also, the DSPL engineer must deal with the hardware and software particularities of the target platform in each CPS deployment. And although each system instantiation has to solve a similar optimization problem of the DSPL, it does not take advantage of experiences gained in similar CPS. Transfer learning aims at improving the efficiency of systems by sharing the previously acquired knowledge and applying it to similar systems. In this work, we analyze the benefits of transfer learning in the context of DSPL and MOEAs testing on 8 feature models with synthetic performance models. Results are good enough, showing that transfer learning solutions dominate up to 71% of the non-transfer learning ones for similar DSPL.","PeriodicalId":416819,"journal":{"name":"Proceedings of the 25th ACM International Systems and Software Product Line Conference - Volume B","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126522569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These variability implementation places are neither explicit nor documented, hampering their detection and variability comprehension. Based on the identification of symmetry property in seven implementation techniques, a first approach was proposed with symfinder to automatically identify and display the variability of a system in a graph-based visualization structured by inheritance. However, composition, or more generally the usage relationship, is extensively used to implement the variability in object-oriented systems, and without this information, comprehending the large amount of variability identified by symfinder is not trivial. In this paper, we present symfinder-2, an extension of the former approach that incorporates the usage relationships to better identify potential variability implementations. We provide two ways to mark classes as entry points, user-defined and automatic, so that the visualization is filtered and enables users to have a better focus when they identify variability. We also report on the evaluation of this extension to ten open-source Java-based systems.","PeriodicalId":416819,"journal":{"name":"Proceedings of the 25th ACM International Systems and Software Product Line Conference - Volume B","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128568389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, researchers often use toy examples or develop fictitious case studies. These are designed to demonstrate their approach but rarely to compare multiple approaches. In this paper, we aim at making variability modeling evaluations comparable. We present and provide a reusable set of four real-world case studies that are easy to access, with artifacts represented in a universal, variability-model-agnostic way, the industrial Product-Process-Resource Domain-Specific Language (PPR DSL). We report how researchers can use the case studies, automatically transforming the Domain-Specific Language (DSL) artifacts to well-known variability models, e.g., product feature models, using the Variability Evolution Roundtrip Transformation (VERT) process. We compare the expressiveness and complexity of the transformed feature models. We argue that the case studies with the DSL and the flexible transformation capabilities build a valuable contribution to making future research results more comparable and facilitating evaluations with real-world product lines.","PeriodicalId":416819,"journal":{"name":"Proceedings of the 25th ACM International Systems and Software Product Line Conference - Volume B","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129299836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To cope with an increasing demand for customization, systems need to exist in concurrent variations at a single point in time (i.e., variability in space). Furthermore, as longevity of systems increases, it is necessary to continuously maintain sequential variations due to evolution (i.e., variability in time). Finally, systems are often built from different kinds of artifacts, such as source code or diagrams, that need to be kept consistent. Managing these challenges - the evolution of variable systems composed of heterogeneous artifacts in a consistent and integrated way - is highly demanding for engineers. To tackle the described challenges, we propose an approach for consistent, view-based management of variability in space and time. Therefore, we study, identify, and unify concepts and operations of approaches and tools dealing with variability in space and time to provide a common ground for comparing existing work and encouraging novel solutions. Furthermore, we identify consistency preservation challenges related to view-based evolution of variable systems composed of heterogeneous artifacts, such as the consistent propagation of changes between products, and across the different types of artifacts. We provide a technique for (semi-)automated detection and repair of variability-related inconsistencies. The goal of this doctoral work is to develop an integrated solution for dealing with the described challenges and, thus, advance state of the art towards uniform management of variability in space and time.","PeriodicalId":416819,"journal":{"name":"Proceedings of the 25th ACM International Systems and Software Product Line Conference - Volume B","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127242237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This additional effort could be reduced if the community adopted a single format. Following the goal of the MODEVAR initiative to develop a widely adopted variability language, we provided a first proposal with the Universal Variability language (UVL) in previous work. For a textual format to be adopted, an important aspect is an as small as possible effort when integrating the format in other tools. In this work, we discuss the integration of UVL in FeatureIDE. We use the integration to examine the applicability of UVL and our parser library to existing tools and gather further requirements for the language design.

Reasoning at the family level yields important economies of scale and quality improvements for a broad range of systems such as software product lines, adaptive and configurable systems. Yet, to fully benefit from the above advantages, a model of the system family's behaviour is necessary. Such a model is often prohibitively expensive to create manually due to the number of variants. For large long-lived systems with outdated specifications or for systems that continuously adapt, the modelling cost is even higher. Therefore, this PhD proposes to automate the learning of such models from existing artefacts. To advance research at a fundamental level, our learning target are Featured Transition Systems (FTS), an abstract formalism that can be used to provide a pivot semantics to a range of variability-aware state-based modelling languages. The main research questions addressed by this PhD project are: (1) Can we learn variability-aware models efficiently? (2) Can we learn FTS in a black-box fashion? (i.e., with access to execution logs but not to source code); (3) Can we learn FTS in a white/grey-box testing fashion?
