* fix(ci): run every helm test suite, not just the first one per file
helm-unittest gained support for multiple suites in one test file in
v0.5.0; CI and the Makefile both pinned v0.4.4, the last release that
decodes a single YAML document per file. Any suite after a `---`
separator was parsed away and its assertions never ran, while the
summary still reported a clean pass.
Upgrading the pin to v0.8.2, the newest release that installs under the
pinned helm 3.11.1, brings the litellm-helm chart from 11 suites / 90
tests to 14 suites / 93 tests with no change to any test file. All the
recovered tests pass.
The run step now compares the number of declared `suite:` documents
against the number of suites the runner reports, so the same class of
silent skip fails the job loudly instead of passing quietly. The
Makefile target upgrades a stale local plugin instead of swallowing the
"already installed" error and leaving the developer on an old version.
* ci: install helm-unittest from a pinned, checksum-verified artifact
`helm plugin install <git url>` clones the plugin repo and executes its
install hook, which downloads the release tarball itself. The old
integrity step then checked the cloned repo's HEAD, which happens after
the hook has already run and never covers the binary that was actually
downloaded.
The plugin now comes from a full pinned release URL, verified against
the SHA-256 the project publishes in its helm-unittest-checksum.sha
sidecar, before anything is unpacked or run. Nothing remote executes
ahead of the check, and a re-published release asset fails the job
instead of installing silently.
The componentized chart at helm/litellm had no way to mount extra
volumes into its deployments, so custom callback or SSO handler code
could not be mounted the way the docs describe for the monolithic
chart. Adds per-component volumes and volumeMounts values for gateway,
backend, and ui, merged with the existing gateway-config volume, plus
a helm-unittest suite for the chart wired into the helm unit test
workflow
