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