# Following four steps are specifically for running automated tests which includes loading the
# mqtt-server image from the GitHub Actions Cache so that the docker compose automated tests can
# use this already built image instead of pulling it from GitHub Container Registry
# Note: These steps are only for the mqtt-server and the manager images and not for the nodered image.
# This is because, currently, docker-compose.automated-tests.yml uses only these two images for running automated tests.
