The shell translator rewrites test bodies and loses Bats reporting. The unit lane needs complete TAP results and JUnit reports without changing how live-cluster suites run. Sourced production helpers still need a dash pass, and unit test bodies need nounset without exporting shell options into subprocesses.

# -----------------------------------------------------------------------------
|
|
# Catches silent regressions in the gpu-operator package's three variants:
|
|
#
|
|
# 1. The base values.yaml pins ccManager.enabled=false and
|
|
# vgpuDeviceManager.enabled=false. Both upstream defaults are now true
|
|
# (chart v26.x). If the next chart bump silently un-pins either one,
|
|
# the `default` (passthrough) variant would gain confidential-computing
|
|
# auto-enable on Hopper hardware (ccManager) or render an mdev DaemonSet
|
|
# that crashloops on Ada+/Blackwell (vgpuDeviceManager). The same union
|
|
# must hold for the `container` variant; the `vgpu` variant re-affirms
|
|
# vgpuDeviceManager=false in its own overlay for the same reason.
|
|
#
|
|
# 2. The sandbox variants must set sandboxWorkloads.defaultWorkload to
|
|
# their own enum value (vm-passthrough / vm-vgpu) — without it, GPU
|
|
# nodes that lack the per-node label nvidia.com/gpu.workload.config
|
|
# fall back to the upstream default 'container' workload, no DaemonSet
|
|
# renders, and the variant is silently a no-op. The container variant
|
|
# relies on the same upstream default but in the opposite direction:
|
|
# with sandboxWorkloads.enabled=false the chart picks defaultWorkload
|
|
# 'container', which is what that variant wants — pinned here so an
|
|
# upstream rename does not silently break it.
|
|
#
|
|
# 3. The vgpu variant must enable the vGPU manager DaemonSet
|
|
# (vgpuManager.enabled=true), the passthrough variant must keep
|
|
# driver.enabled / devicePlugin.enabled at false, and the container
|
|
# variant must keep driver / toolkit / vfioManager at false (host
|
|
# already provides them) while keeping devicePlugin enabled (publishes
|
|
# nvidia.com/gpu to the kubelet). The container variant must also pin
|
|
# cdi.enabled=false: upstream defaults it true, but CDI specs are
|
|
# serviced by the toolkit DaemonSet this variant disables, so leaving
|
|
# it on points the device plugin at CDI injection with no specs on an
|
|
# apt host and silently breaks allocation.
|
|
#
|
|
# Implementation: render the chart with the merged values for each variant
|
|
# and grep for the relevant ClusterPolicy keys. We strip the package's
|
|
# 'gpu-operator:' Helm-subchart prefix because we render the subchart
|
|
# directly here — the prefix is meaningful only when the parent wrapper
|
|
# chart is in play.
|
|
#
|
|
# Compatible with both `bats` directly and the in-repo cozytest.sh runner.
|
|
# cozytest.sh runs each @test in a fresh subshell with `set -u` and does
|
|
# not honor bats setup()/teardown(), so we provision TMP inline per test.
