CSlicerCloud: a web-based semantic history slicing framework.

Traditional commit-based sequential organization of software version histories is insufficient for many development tasks which require high-level, semantic understanding of program functionality, such as porting features or cutting new releases. Semantic history slicing is a technique which uses well-organized unit tests as identifiers for corresponding software functionalities and extracts a set of commits that correspond to a specific high-level functionality. In this paper, we present CSlicerCloud, a Web-based semantic history slicing service tailored for Java projects hosted on GitHub. It is accessible through Web browsers and powered in the backend by a collection of history slicing techniques underneath. We evaluated CSlicerCloud on a dataset containing developer-annotated change histories collected from 10 open source software projects. A video demonstration which showcases the main features of CSlicerCloud can be found at https://youtu.be/7kcswA0bQzo.
