Research addressing the lack of datasets for real world SStuBs (Simple Stupid Bugs) in source code, which has resulted in the use of synthetic data for evaluating fault localization techniques. SStuBs consist of small semantics bugs which are syntactically correct and thus hard for a developer to manually spot. The project's main goal is to build an end-to-end system for automatically repairing SStuBs. The "ManySStuBs4J Dataset" is a large dataset of single statement bug-fix changes, mined from open-source Java projects hosted in GitHub.
