suite: chart-managed scheduled backup gating

# Locks in the dual-gate on cnpg.io/ScheduledBackup. The chart's legacy
# scheduled-backup template used to render whenever backup.enabled was
# true, which forced users who only wanted archive_command running (so a
# BackupClass driver could take ad-hoc / Plan-driven backups against a
# live WAL archive) to also accept a chart-emitted hourly ScheduledBackup
# they did not ask for.

templates:
  - templates/backup.yaml

tests:
  - it: does not render when backup is disabled
    release:
      name: pg-test
      namespace: tenant-test
    set:
      backup:
        enabled: false
    asserts:
      - hasDocuments:
          count: 0

  - it: does not render when schedule is empty even with backup enabled
    release:
      name: pg-test
      namespace: tenant-test
    set:
      backup:
        enabled: true
        schedule: ""
    asserts:
      - hasDocuments:
          count: 0

  - it: does not render under useSystemBucket even with schedule set
    # In the platform useSystemBucket flow the Cluster's barmanObjectStore
    # is left unset until the BackupClass driver SSA-patches it at first
    # BackupJob time, so a chart-emitted ScheduledBackup would fire against
    # an unconfigured Cluster and fail. Mirrors the ClickHouse gates.
    release:

        schedule: "0 2 * * * *"
    asserts:
      - hasDocuments:
          count: 0

  - it: renders ScheduledBackup when both enabled and schedule are set
    release:
      name: pg-test
      namespace: tenant-test
    set:
      backup:
        enabled: true
        schedule: "0 2 * * * *"

          value: pg-test
      # The ScheduledBackup must delegate to the barman-cloud plugin, not the
      # deprecated native barmanObjectStore method (removed in CNPG 1.29).

  - it: default values produce no ScheduledBackup
    # Defends the new default - users who deploy with no overrides do not
    # get a surprise hourly backup chain that competes with whatever
    # BackupClass policy the platform may have applied. backup.enabled
    # defaults to false anyway; the assertion is here so a future change
    # that flips that default does not silently re-enable the legacy path.
