FUSE (The Future of Software Engineering) Lab is a research collaboration between TU Delft’s Software Engineering Research Group (SERG) and Meta’s DevInfra team, rethinking the future of software development in the age of AI. Within FUSE, I co-lead Track 2 — Predictive Software Testing — which aims to create an intelligent and adaptive testing ecosystem capable of safeguarding quality in massive, rapidly-evolving codebases. The track explores learning-based techniques (e.g., LLMs and agents) to capture the intent behind code changes, new metrics for test quality that go beyond code coverage, prediction of code-change success to give developers quick feedback, and autonomous agents that automatically refactor, prune, and optimize test code to prevent test decay.
