# Tests for lint-prod-gate.sh — the post-promote pinned-ness gate extracted from
|
|
# .github/workflows/showcase_promote.yml (UNIT U12, spec §8.2).
|
|
#
|
|
# Core invariant under test: after a promote, EVERY prod service must be pinned
|
|
# to an immutable `@sha256:` digest. A born-on-`:latest` service (the
|
|
# deploy-to-railway.ts unpinned-source case, spec R-E) must be caught LOUD — the
|
|
# gate exits non-zero so the verify-prod job (and the run) goes red. A
|
|
# fully-pinned fleet passes (exit 0).
|
|
#
|
|
# The gate is a thin wrapper around `bin/railway lint-prod`, whose exit-code
|
|
# contract IS the assertion: exit 1 on findings (an unpinned prod service), exit
|
|
# 0 when all pinned, exit 2 on a hard error. The real `bin/railway` is replaced
|
|
# on PATH-independent terms via RAILWAY_BIN, pointed at a stub that mimics those
|
|
# exit codes. The gate's job is to (a) invoke `lint-prod` with the right
|
|
# subcommand and (b) FAIL the step (propagate the non-zero) when lint-prod finds
|
|
# an unpinned service — never swallow it.
|
|
#
|
|
# NB on assertion gating: bats does NOT run test bodies under `set -e`. Only the
|
|
# FINAL command decides pass/fail, so every non-final assertion is written
|
|
# `[[ ... ]] || fail "msg"` to force a hard failure with a diagnostic. A bare
|
|
# `[[ ... ]]` on a non-final line is a silent no-op (false-green).
|
|
|
|
# fail <msg> — print the message to the bats failure stream and abort the test.
