# certctl End-to-End Test Script
# =============================================================================
#
# Automates the full lifecycle test from docs/test-env.md:
#   1. Bring up all 7 containers (build from source)
#   2. Wait for every service to be healthy
#   3. Verify pre-seeded data (agents, issuers, targets)
#   4. Issue a certificate via Local CA → deploy to NGINX → verify TLS
#   5. Issue a certificate via ACME/Pebble → verify
#   6. Issue a certificate via step-ca → verify
#   7. Test revocation + CRL
#   8. Test discovery
#   9. Test renewal (re-issue step-ca cert, check version history)
#  10. Print summary
#
# Usage:
#   cd certctl/deploy
#   ./test/run-test.sh          # full run (build + test)
#   ./test/run-test.sh --no-build   # skip docker build, reuse existing containers
#   ./test/run-test.sh --no-teardown # leave containers running after test
#
# Requirements: docker, curl, openssl, jq (or python3 for json parsing)
