test(bdd): add Helm release deployment assertion

[sbaum1994]

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)

• go test -short ./... from tests/bdd: passed.
• ./scripts/lint.sh from tests/bdd: passed with 0 issues.
• TestSingleClusterHelmfile: 5 scenarios, 49 steps passed on a fresh local topology.
• TestMultiClusterHelmfile: 5 scenarios, 69 steps passed on a fresh local topology, with the disclosed live-only correction for Self-managed NVCT tasks use the function ICMS request action #1032.
• Both test topologies were destroyed after validation. QA is not required for the DSL change; Self-managed NVCT tasks use the function ICMS request action #1032 tracks a clean NVCT task rerun.

📝 Walkthrough

Walkthrough

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

Changes

Helm release assertions

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 Helm expectation data, explicit-context command construction, and validation for 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 the Helm command, and validates the output.
Feature scenario migration tests/bdd/features/*.feature, tests/bdd/PLAN.md	Replaces direct Helm 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, tests/bdd/fixtures_test.go	Updates canned Helm responses to all-namespaces listings, adds nvca-operator to shared fixtures, disables selected feature gates, and tests the resulting fixture values.

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

Merge Risk: 🔵 Low · up to 4298b

The PR adds explicit Helm release assertions and adjusts local test fixtures; the remaining bounded risk is that the fake-GPU feature-gate configuration is not explicitly checked for exact names or disabled polarity. The change is mergeable with owner awareness or follow-up.
