# Tests for publish.sh -- the one script in this repo that needs real
# network to do its actual job (fdroid-repo-ci#1), so its happy path against
# a genuine bucket is out of scope for most of this file. What this asserts:
#
# * argument/credential validation, offline;
# * `--dry-run` builds the exact command(s) a real run would use for
#   whichever of --files-only/--index-only (or neither -> both, files then
#   index) is selected, offline;
# * a real invocation against a closed local port fails on the network call
#   itself -- during the credential check specifically, before any upload is
#   attempted -- proving both that the constructed command is well-formed
#   and that verification genuinely comes first (fdroid-repo-ci#5);
# * a real invocation against a tiny local HEAD-only S3 stub (test_s3_stub.py)
#   proves the credential check is a genuine authenticated call (a wrong
#   bucket is rejected, not waved through because a variable was merely
#   non-empty), that an already-published APK is refused before any upload
#   (and that --index-only alone never runs that check at all, since it
#   cannot upload an APK) -- and, as a negative control, that a
#   *non*-colliding APK does NOT trip the same check (fdroid-repo-ci#6);
# * the opt-in live round trip against a real bucket, extended to prove the
#   two-pass ordering **by construction**: `--files-only` then `--index-only`
#   as two genuinely separate invocations, with the bucket state asserted in
#   between -- no synchronization hook, no `eval` of anything in this public
#   repo's production script -- plus the APK-collision refusal against a
#   real object, and a deliberate-misuse case proving `--index-only` alone
#   really does produce the exact state the ordering guarantee exists to
#   prevent (an index naming a file that is not there), which the *default*
#   path never reaches.
