Working Group: Code Coverage Tool for R
Code coverage helps to ensure greater software quality by reporting how thoroughly test suites cover the various code paths. Having a tool that supports the breadth of the R language across multiple platforms, and that is used by R package developers and R core teams, helps to improve software quality for the R Community. While a few code coverage tools exist for R, this Oracle-proposed ISC project aims to provide an enhanced tool that addresses feature and platform limitations of existing tools via an ISC-established working group. It also aims to promote the use of code coverage more systematically within the R ecosystem.
The Code Coverage group released a revised covr package over the summer 2017 (see https://www.r-consortium.org/blog/2017/06/28/code-coverage-tool-for-r-working-group-achieves-first-release).
