# Suite for packages/queue (issue #1508). Every test runs in scratch
# repositories under the system temp directory; nothing touches this
# checkout's .git, lock, witness or queue files.
#
#   scripts/test-queue.sh            full run
#   NO_COLOR=1 scripts/test-queue.sh plain output
#
# Once HEAD holds docs/plans/queue.json (the genesis commit), the suite also
# runs `verify` and `render --check` on the live queue through
# `scripts/mosaic queue`. Each takes the queue lock for a moment and writes
# nothing. Before genesis, or in a checkout that is not the queue's
# canonicalRoot (an export or a review clone), it skips them and says why;
# `scripts/mosaic queue help` still runs, reading no queue file and taking no
# lock.
