integration-tests.yml

# AUTOGENERATED by pre-commit, modify the .in file instead.

# integration-tests.yml.in is used to generate integration-tests.yml by
# expanding yaml anchors, because github actions don't support them
# (https://github.com/actions/runner/issues/1182).  pre-commit will do this for
# you automatically.
