# For testing, you can set variables in your repo (Repo -> Settings ->
# Security -> Actions -> Variables) to restrict the tests that are run.
# The supported variables are:
#
# RUN_ONLY_TARGET_CONFIG: Run only the single matching target and config,
#   separated by spaces, eg "ubuntu-latest default".  All other tests will
#   fail immediately.
#
# LTESTS: Override the set of tests run.
