Google Summer of Code 2022 Blog

This blog is intended to include all of my progress throughout the Google Summer of Code 2022. In this Google Summer of Code edition I will contribute to the RcppDeepState project for The R Project for Statistical Computing organization.

Project description

Fuzzing is a useful technique for finding and avoiding programming problems by sending programs invalid sets of non-deterministic inputs. The RcppDeepState package allows developers to perform fuzz testing on libraries that use Rcpp for some specific functionalities. The main purpose of this project is to provide a custom GitHub Action that makes it simple for developers to use RcppDeepState’s fuzzing techniques on any R package on GitHub. In addition, improvements to the existing RcppDeepState library will also be implemented in order to proceed with the publication of the package on CRAN.
