Dynamic Software Product Line (DSPLs) based Systems are capable of adapting inresponse to changes concerning their observations at runtime in order toexhibit appropriate behavior. The observation space and the variability in theconfiguration space is usually known at design time. However, running a set oftests with all combinations of configuration and observation from these spacesis likely to be...
In order to reduce the complexity of modeling product lines, many authors propose modeling product concerns separately by using multiple feature models. These proposals use well-known operations such as merge, union and slice to compose the models for analysis and engineering. Such operations produce new models that represent sets of products that comply with the semantics of the operations. We use...
Software Product Line (SPL) consists in an approach that enables software reuse by allowing the creation of software applications through the features composition to address a particular domain. Framework Product Line (FPL) is an extension of SPL, whose features composition result in targeted frameworks, which are used to address subdomains of applications. Model-Driven Engineering is a promising...
Testing every product of a software product line (SPL) is often not feasible due to the exponential number of products in the number of features. Thus, the order in which products are tested matters, because it can increase the early rate of fault detection. Several approaches have been proposed to prioritize products based on configuration similarity. However, current approaches are oblivious to...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Summary form only given, as follows. VACE 2017 Workshop Summary. Many of today's software systems must accommodate a wide range of usage and deployment scenarios (e.g., product lines/families, self-adaptive systems, configurable or customizable single systems, open platforms, contextaware mobile apps, dynamic service-based systems). This variability can occur in software functionality and quality...
Managing variability is a hard task for every technique that develops variability-rich systems, such as software product lines (SPL), especially in its evolution. Hence, to be effective a technique should provide stability and respect the Open-Closed principle. Among the techniques to develop SPLs, delta-oriented programming (DOP) seems to be promising given its flexibility. There are two strategies...
Applications based on micro or web services have had significant growth due to the exponential increase in the use of mobile devices. However, using such kind of loosely coupled interfaces provides almost no guarantees to the developer in terms of evolution. Changes to service interfaces can be introduced at any moment, which may cause the system to fail due to mismatches between communicating parts...
Mutation testing is a technique to evaluate the quality of test cases by assessing their ability to detect faults. Mutants are modified versions of the original program that are generated automatically and should contain faults similar to those caused by developers' mistakes. For configurable systems, existing approaches propose mutation operators to produce faults that may only exist in some configurations...
