TL;DR

Replace 14 repeated helm list -o json plus JSON-row checks with one explicit-context, table-driven Helm release assertion. This keeps release name, namespace, and optional revision visible while hiding output-format plumbing.

Additional Details (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)

Why:

  • The repeated command and JSON checks obscure the deployment contract and make profile features harder to read.
  • Live validation on current main also exposed implicit local defaults that prevented the generic Helmfile suites from reaching their workload checks reliably.

What changed:

  • Added Then these Helm releases should be deployed using context ... with required name and namespace columns and an optional revision column.
  • The step runs one all-namespaces Helm query, requires deployed status, and identifies missing, misplaced, wrong-status, or wrong-revision releases.
  • Migrated all 14 existing Helm release checks without weakening the observability revision assertions.
  • Made the generic local Helmfile scenarios explicitly select the disabled observability profile. Dedicated profile features retain observability coverage.
  • Disabled resource-sizing enforcement in the fake-GPU fixtures so dynamic discovery retains the 1x type used to report laptop-cluster GPU capacity.

Customer release notes: Not customer visible.

Plan summary: Not applicable.

Usage:

Then these Helm releases should be deployed using context "k3d-ncp-local":
  | name | namespace |
  | api  | nvcf      |

Dependencies: None. No license review or NOTICE update is required.

For the Reviewer

Focus on tests/bdd/dsl/helm.go, the step adapter, and the optional revision case in observability-all.feature.

The multi-cluster live run exposed #1032. The suite passed after correcting that one live task request from the function action to the task action; no workaround for that separate defect is included here.

For QA (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)

Summary by CodeRabbit

  • New Features

    • Added a BDD assertion for verifying deployed Helm releases by Kubernetes context, name, namespace, status, and optional revision.
    • Helm release checks now support all namespaces and provide clearer validation errors.
  • Bug Fixes

    • Updated multi-cluster and single-cluster deployment checks to use context-aware release verification.
    • Improved local test fixtures for resource-limit and observability configuration.
  • Tests

    • Added coverage for missing releases, mismatched namespaces, statuses, revisions, invalid contexts, and malformed output.

Replace repeated Helm JSON plumbing with an explicit-context table step that preserves optional revision checks and names mismatched releases. Keep the local Helmfile fixtures deterministic against current observability and NVCA sizing defaults so the migrated live suites remain runnable.

Review Change Stack

📝 Walkthrough

Walkthrough

Adds a reusable Helm release deployment assertion with explicit Kubernetes context, namespace, status, and optional revision checks. Migrates BDD feature scenarios and wiring fixtures from direct Helm JSON assertions.

Changes

Helm release assertion

Layer / File(s) Summary
Helm DSL contracts and validation
tests/bdd/dsl/helm.go, tests/bdd/dsl/helm_test.go, tests/bdd/PLAN.md
Adds HelmReleaseExpectation, HelmListCommand, and HelmReleasesDeployed. Validation checks release name, namespace, deployed status, optional revision, missing releases, malformed JSON, and empty contexts.
BDD step parsing and execution
tests/bdd/steps/assertion_steps.go, tests/bdd/steps/steps_test.go
Registers the table-driven assertion step. It parses required name and namespace columns, accepts optional revision, executes an explicit-context Helm command, and validates the result.
Feature scenario migration
tests/bdd/features/*.feature, tests/bdd/PLAN.md
Replaces direct helm list JSON and status checks with context-aware deployment assertions across single-cluster, multi-cluster, and observability scenarios.
Wiring fixtures and environment overrides
tests/bdd/godog_test.go, tests/bdd/fixtures/*.yaml
Updates canned Helm responses to all-namespaces listings with explicit contexts, adds nvca-operator to shared fixtures, and adds local feature-gate overrides.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to b0ec0

The PR consolidates Helm release assertions and updates related BDD fixtures and scenarios; no actionable merge-blocking risk remains, so it is merge-ready after normal checks and review.

Add coverage for the feature-gate fixture contract.

The wiring fixture seeds in tests/bdd/godog_test.go do not include these five values. The supplied tests do not assert the gate names or their disabled polarity. Add a test that parses both shipped fixtures and verifies the exact five featureGateValues.

  • tests/bdd/fixtures/nvcf-compute-plane-local-bdd-multi.yaml#L35-L42: Assert all five disabled feature gates.
  • tests/bdd/fixtures/nvcf-compute-plane-local-bdd.yaml#L29-L36: Assert the same five disabled feature gates.

As per coding guidelines: "Code changes must include tests."
