test(bdd): cover Helm function rendering - #1865
Conversation
Exercise the ReVal chart-rendering boundary through a live Helm-backed function lifecycle. Document the public sample chart contract and verify the feature wiring passes the chart reference to nvcf-cli. Fixes #1863 Signed-off-by: Stephanie Baum <sbaum@nvidia.com>
📝 WalkthroughWalkthroughThe BDD suite now covers Helm-backed function lifecycles in single- and multi-cluster Helmfile runs. Wiring tests validate chart configuration, Helm invocation commands, responses, and updated deployment counts. ChangesHelm-backed function lifecycle

TL;DR
Add live Helm-backed function lifecycles to the single-cluster and multi-cluster self-managed BDD suites so ReVal chart-rendering failures are observed through the public API.
Additional Details
Why
The BDD suite installed ReVal and exercised container-backed HTTP, gRPC, and LLM functions, but no scenario supplied
helmChart. A healthy ReVal pod was therefore enough for the stack checks even when every authenticated render request failed.Several layers missed the regression for different reasons:
config.yamlkeys matched the ReVal runtime schema.go test -shortand are not run by the public premerge workflow.The focused chart contract test merged in #1862 now protects the configuration shape during premerge validation. This PR adds the missing live product behavior coverage.
What changed
nvcf-cli.ncp-local-compute-1backend./echo, assert the response, and remove the deployment.SAMPLE_HELM_FUNCTION_CHARTso the features do not hard-code a released artifact version.Customer Release Notes
Not customer visible.
Plan Summary
Not applicable.
Usage
Set
SAMPLE_HELM_FUNCTION_CHARTto a chart that ReVal can fetch without credentials. The chart must expose anentrypointService on port 8000, answer/health, and echo request messages from/echo.Testing
Passed:
cd tests/bdd && go test -short ./...tests/bdd/scripts/lint.sh./tools/ci/check-docsgit diff --checkThe live scenarios were not run locally because they require registry credentials, a published sample chart, and disposable k3d environments. QA should run the live commands described below.
Notes
No architecture diagram update is needed. The tests cover the existing function creation, ReVal rendering, NVCA deployment, and invocation flow in both supported Helmfile topologies.
Issue #1871 tracks replacing the raw Helm function-create commands with a table-backed BDD step.

Dependencies
None. No license review or NOTICE update is required.
For the Reviewer
Please verify that the scenarios remain outside-in: all product actions use
nvcf-cli, and the assertions check invocation responses instead of internal Kubernetes or service state.For QA
QA is required. Provide a compatible public chart and run each topology independently:
Each Helm function scenario must fail when ReVal rejects the render request and pass only after the deployment becomes invokable.
