FauxPy: A Fault Localization Tool for Python Programs

Speaker: Mohammad Rezaalipour

Fault localization is the process of finding buggy program entities, such as statements or functions, in a program’s source code. Several families of fault localization techniques have been proposed in the literature, using different sources of information or targeting different program entities. However, despite its popularity and its error-proneness due to being a dynamically typed language, not much research has been done on fault localization for the Python programming language. In this seminar, I will present a live demo of FauxPy, a fault localization tool I developed for Python. Currently, FauxPy is the only fully automated tool that implements several fault localization techniques for Python programs. FauxPy currently supports spectrum-based, mutation-based, stacktrace-based, and predicate switching fault localization. During the demo, I will demonstrate some of these fault localization techniques and compare their effectiveness and efficiency. Using FauxPy, we plan to conduct the first fault localization empirical study on Python programs in different domains (from end-user applications to data science programs such as those based on neural networks).

Moe is a PhD student at the ATOM group, working under the supervision of Prof. Carlo Alberto Furia, and he works on implementing different techniques to aid the debugging of data science programs. Moe joined SI three years ago as a PhD student, and before that, he did his Master’s degree at Shahid Beheshti university in Tehran, researching software testing and automated program repair.

Chair: Luca Pascarella

ℹ️ The seminar will be in presence for everyone in Room D0.02. If you are unable to attend in presence, the SI website contains a link to a Teams video call in the “location" field (i.e., click on “D0.02"). 


In February 2019, the Software Institute started its SI Seminar Series. Every Thursday afternoon, a researcher of the Institute will publicly give a short talk on a software engineering argument of their choice. Examples include, but are not limited to, novel interesting papers, seminal papers, personal research overview, discussion of preliminary research ideas, tutorials, and small experiments.

On our YouTube playlist you can watch some of the past seminars. On the SI website you can find more details on the next seminar, the upcoming seminars, and an archive of the past speakers.

Everyone is welcome to attend the seminars organized by the Software Institute.
