Automated testing in XGBoost project

This document collects tips for using the Continuous Integration (CI) service of the XGBoost project.

GitHub Actions

The configuration files are located under the directory .github/workflows.

Most of the tests listed in the configuration files run automatically for every incoming pull requests and every update to branches. A few tests however require manual activation:

• R tests with noLD option: Run R tests using a custom-built R with compilation flag --disable-long-double. See this page for more details about noLD. This is a requirement for keeping XGBoost on CRAN (the R package index). To invoke this test suite for a particular pull request, simply add a review comment /gha run r-nold-test. (Ordinary comment won’t work. It needs to be a review comment.)
