About

I am assistant professor at the Department of Informatics of Universidade do Minho, where I regularly teach courses on programming and formal methods for software engineering, and also a member of the High-Assurance Software Laboratory of INESC TEC. In recent years, my research is focused on the topic of formal methods for software engineering, namely developing new languages and tools for formal modeling, including validatiom and verificaiton, and for bidirectional model transformation. Recently, I've also started to research the topic of robotic software quality, in particular software developed for the Robot Operating System.

Abstract
Effective testing of message-oriented software requires describing the expected behaviour of the system and the causality relations between messages. This is often achieved with formal specifications based on temporal logics that require both first-order and metric temporal constructs - to specify constraints over data and real time. This paper proposes a technique to automatically generate tests for metric first-order temporal specifications that match well-understood specification patterns. Our approach takes in properties in a high-level specification language and identifies test schemas (strategies) that are likely to falsify the property. Schemas correspond to abstract classes of execution traces, that can be refined by introducing assumptions about the system. At the low level, concrete traces are successively produced for each schema using property-based testing principles. We instantiate this approach for a popular robotic middleware, ROS, and evaluate it on two systems, showing that schema-based test generation is effective for message-oriented software.

Validating the Hybrid ERTMS/ETCS Level 3 concept with Electrum

Abstract
This paper reports on the development of a formal model for the Hybrid ERTMS/ETCS Level 3 concept in Electrum, a lightweight formal specification language that extends Alloy with mutable relations and temporal logic operators. We show how Electrum and its Analyzer can be used to perform scenario exploration to validate this model, namely to check that all the operational scenarios described in the reference document are admissible, and to reason about expected safety properties, which can be easily specified and model checked for arbitrary track configurations. We also show how the Analyzer can be used to depict scenarios (and counter-examples) in a graphical notation that is logic-agnostic, making them understandable by stakeholders without expertise in formal specification. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.
