# tests_entry.yml
# Entry point to the test suites
#
# - If neither ci:run, ci:run_full or ci:ready_to_merge labels are on PR, fail and exit.
# - If the PR comment body doesn't contain 'BUG=' fail and exit.
# - If ci:run or ci:run_full label is on PR, remove label and run the test scripts.
# - If ci:ready_to_merge is on the PR and the pull_request_target type is synchronize not triggered
#   by the mergify[bot] user, remove label and fail job.
# - If ci:ready_to_merge label is on PR and pull_request_target type is labeled, run the test scripts.
#
# The end result is labeling ci:run or ci:ready_to_merge will run the test scripts,
# If Mergify merges to the PR, the test scripts will run. If anyone else tries to add
# a commit to the PR or merge , the script will fail and ci:ready_to_merge will be
# removed.
#
# This script runs the test scripts directly. Scheduled or manual runs use
# run_<scriptname>.yml as the entry point.
