I am a Ph.D. candidate in Informatics at Università della Svizzera italiana (Lugano, Switzerland) under the supervision of prof. Mauro Pezzè. My projects focus on the automatic generation of test oracles, and in my research I derive them from software-related artifacts expressed in natural language.

Before joining the PhD programme in 2018, I was a research intern at the IMDEA Software Institute (Madrid, Spain) working with Alessandra Gorla -- now my PhD co-advisor. During that period I obtained my M.Sc. from the University of Milano-Bicocca (Milan, Italy).

I have interned at Facebook (London, UK) for Summer 2021 to work with the Sapienz team, and I plan to join them full time in 2022

  • Jdoctor
    Jdoctor (originally known as Toradocu) is a tool that takes in input the Java source code of a class, extracts the Javadoc semi-structured comments at the method level, and translates @param, @return and @exception tags into executable specifications. Such specifications can act as test oracles and can be integrated with an automatic test case generator: Jdoctor is currently integrated with Randoop. Up to now, Jdoctor's precision and recall computed over 800 translations are respectively above 90% and 80%.
  • RepliComment
    RepliComment is a prototype born in 2018 that takes in input the Java source code of a whole project and searches for comment clones at the method and field level. RepliComment relies on some heuristics to understand whether a comment clone could be legitimate (e.g. overriding) or if there is an issue such as an unintentional mistake of copy-and-paste. RepliComment was extended in 2020: Now it automatically assesses the severity of the clones and provide fix suggestions for the copy-and-paste mistakes.
  • MeMo
    MeMo is a tool that takes in input the Java source code of a class and extracts method summaries (i.e., unstructured comments) to look for metamorphic relations. If found, a MR is translated into an executable assertions that can be automatically integrated into existing test suites. MeMo so far discovered over 250 MRs across different Java projects which it can translate with good precision and recall. The translations, when used as assertions, prove to help both regression and developers-written assertions in bug detection.
