Primary CI runs on MongoDB’s Evergreen system.
Configuration lives in .evergreen/.
.evergreen/ configuration without reviewAfter modifying .evergreen/ files, validate the config locally:
evergreen validate .evergreen/.evg.yml
Always run this before submitting changes to .evergreen/ to catch syntax errors and invalid task definitions.
To test your changes on Evergreen before merging, create a patch build:
evergreen patch -u
This uploads your uncommitted and committed local changes as a patch build on Evergreen, allowing you to run the full CI test matrix against your branch.
