Brief Bio
Antonia Bertolino is a Research Director of the Italian National Research Council (CNR), in Pisa. She is an internationally renowned researcher in Software Engineering, having more than 150 co-authored papers in peer-reviewed journals and conference proceedings. She investigates approaches for software and services validation, testing, and monitoring, and on these topics has worked in several national and European projects, including the most recent Learn PAd, CHOReOS, and NESSOS. Currently she serves as an Area Editor for the Elsevier Journal of Systems and Software, and as an Associate Editor of ACM Transactions on Software Engineering and Methodology, and of Springer Empirical Software Engineering. She has recently been the General Chair of the flagship ACM/IEEE Conference ICSE 2015, Florence (Italy). She serves regularly in the Program Committee of the most renowned conferences in the field of Software Engineering, such as ESEC-FSE and ICSE, and in software testing and analysis, as ISSTA and ICST.
Abstract
Software testing can be driven by different criteria, among which code coverage and usage profile are widely used.
The former aims at exercising as much as possible the program elements (e.g., the statements), the latter aims at increasing the predicted reliability in operation.
The question whether there is any correlation between these two goals remains still open.
On the other side, the relations between the two research fields are loose.
In this talk I will discuss about potential ways and benefits of combining the two testing approaches, advocating the convenience of a tighter relationship.

Brief Bio
Davide Rossi, Ph.D, is a Research Associate (Assistant Professor) at the Department of Computer Science at the University of Bologna.
His main research area include software engineering, coordination models and languages, process modeling, web-based collaborative platforms.
He teaches/has teached graduate courses in Web Engineering, Business Process Management, Service Oriented Architectures and Software Architectures.
He has been a member of the European Research Projects PageSpace (ESPRIT Open LTR project, contract number 20179) and Adapt (Shared-Cost RTD Project funded by the Information Society Technologies Programme of the European Commission under FP5). He also participated in the TAPAS project (Shared-Cost RTD Project funded by the Information Society Technologies Programme of the European Commission under FP5).
He spent 6 month as visiting scientist at the Computer Science Department of the Yale University.
He is the author of more than fifty published contributions in the form of journal articles, international conference/workshop proceedings papers and book chapters.
Abstract
While today’s IT social media presence is dominated by microservices and REST-based APIs (with increasing competition from GraphQL), Service Oriented Architectures implemented on top of SOAP continue to be featured in many B2B projects and reports of their death have been greatly exaggerated.
In fact, for the most part, microservices have not replaced enterprise SOAs, but have eased a new, much wider audience, into embracing (web) services-based solutions. An audience for which the multilayered XML-based machinery behind SOAP was perceived as intimidating (and JEE so old-fashioned). By looking at real-world examples of deployed microservices-based systems, however, it is easy to realize that, when dealing with stringent non-functional requirements, they are at least as complex as enterprise SOA solutions. Complexity is just moved around.
By taking a software engineering perspective, this talk will present a few discussion topics related to service-based architectures and non-functional software qualities. Strengths and shortcomings of microservices when facing non-trivial quality concerns will be discussed, providing a foundation on which informed decisions can be taken when designing a (service-based) software architecture.

Brief Bio
Oscar Pastor is Full Professor and Director of the "Centro de Investigación en Métodos de Producción de Software (PROS)" at the Universidad Politécnica de Valencia (Spain). He received his Ph.D. in 1992. He was a researcher at HP Labs, Bristol, UK. He has published more than two hundred research papers in conference proceedings, journals and books, received numerous research grants from public institutions and private industry, and been keynote speaker at several conferences and workshops. Chair of the ER Steering Committee, and member of the SC of conferences as CAiSE, ICWE, CIbSE or RCIS, his research activities focus on conceptual modeling, web engineering, requirements engineering, information systems, and model-based software production. He created the object-oriented, formal specification language OASIS and the corresponding software production method OO-METHOD. He led the research and development underlying CARE Technologies that was formed in 1996. CARE Technologies has created an advanced MDA-based Conceptual Model Compiler called OlivaNova, a tool that produces a final software product starting from a conceptual schema that represents system requirements. He is currently leading a multidisciplinary project linking Information Systems and Bioinformatics notions, oriented to designing and implementing tools for Conceptual Modeling-based interpretation of the Human Genome information.
Abstract
With decades of contributions and applications, conceptual modeling is very well-recognized in information systems engineering. However, the importance and relevance of conceptual modeling in the Web Engineering domain is less well understood. Being Web application development a complex, challenging field that is in continuous evolution and that has high demands in the context of the digital era that we are witnessing, conceptual modeling should play a basic role oriented to design correct Web application development processes. From a web programming perspective, conceptual modeling -even being implementation-independent- should be able to describe a system in sufficient detail so that the model can be automatically compiled into an executable system. This keynote will face this issue, focusing on the problems that conceptual modeling approaches face to provide those required efficient software development solutions, emphasizing the particularities that modeling Web applications presents.
