# Unit tests for hack/e2e-chainsaw/_lib/remediation-guard.sh
#
# helmrelease_has_remediation_cycle takes a newline-delimited list of
# HelmRelease history snapshot status values (deployed/superseded/failed/
# uninstalled/...) and returns 0 when any entry is "failed" or "uninstalled"
# (meaning flux helm-controller performed install/upgrade remediation).
#
# This is used by the e2e script after the HelmRelease reaches Ready. The
# failure/upgrade counters (.status.installFailures / .status.upgradeFailures)
# are useless there because flux's ClearFailures zeroes them on successful
# reconciliation; .status.history retains the snapshot trail.
#
# CI runs this file under Bats through `make bats-unit-tests`. It also remains
# compatible with the legacy `hack/cozytest.sh` translator, whose awk parser
# recognizes only @test blocks and a bare `}` on its own line. The tests avoid
# `run` and `$status` for that compatibility path and use direct shell assertions.
#
# Run with: bats hack/remediation-guard.bats
