test(bdd): add Kubernetes readiness assertions

[sbaum1994]

TL;DR

Add explicit-context BDD steps for Kubernetes deployment rollouts and NVCFBackend agent status, then migrate the local and EKS Helmfile features that repeat those waits.

Additional Details

Raw kubectl command and exit-code pairs made the intent harder to scan. The new steps keep the deployment or backend name, namespace, context, expected status, and timeout visible while centralizing validation, shell quoting, and secret-safe failures.

The two issues are grouped because they share the same Kubernetes readiness seam and affected features.

For the Reviewer

Focus on command construction in tests/bdd/dsl/kubectl.go and the abstraction level of the migrated Gherkin. Merged PR #1077's Kubernetes YAML assertion remains registered alongside these steps.

For QA

Live local single- and multi-cluster coverage was run. Live EKS validation is still needed and tracked in #1087.

Customer Release Notes

Not customer visible.

Plan Summary

Not applicable.

Usage

Feature files can assert rollout completion or NVCFBackend agent status without spelling out kubectl and a separate exit-code assertion. Namespace, context, status, and timeout remain explicit in Gherkin.

Testing

• go test -short ./...: passed after rebase.
• golangci-lint run --config .golangci.yml ./...: 0 issues after rebase.
• TestSingleClusterHelmfile: passed, 6 scenarios and 65 steps.
• TestObservabilityCompute: passed, 1 scenario and 43 steps.
• TestObservabilityAll: passed, 1 scenario and 35 steps.
• TestSingleClusterUpOneClick: passed, 1 scenario and 12 steps, with the missing local environments and OUTPUT_DIR supplied as workarounds for test(bdd): Author local environments in one-click feature #1090 and fix(cli): Set compute-plane OUTPUT_DIR during self-hosted up #1091.
• TestMultiClusterHelmfile: install, registration, rollout, and backend-health scenarios passed. The later NVCT task scenario failed because the installed pre-fix(nvct): request task instances from SIS #1042 image emits the legacy function action; publishing and consuming the fix is tracked in build(nvct): Publish and consume task-action fix in self-hosted stack #1093.
• EKS feature wiring passed under the short suite. Live EKS was not run.

Notes

The local E2E runs used only /tmp/kubeconfig-k3d-ncp-local and explicitly named k3d contexts. No ambient EKS context was used.

📝 Walkthrough

Walkthrough

Added BDD assertions for Kubernetes deployment rollouts and NVCFBackend agent status. The assertions validate explicit targets, build commands, report contextual failures, and replace repeated raw kubectl checks across feature scenarios.

Changes

BDD Kubernetes readiness assertions

Layer / File(s)	Summary
Kubernetes wait command builders tests/bdd/dsl/kubectl.go, tests/bdd/dsl/kubectl_test.go	Added validated, interpolated command builders for deployment rollout and NVCFBackend agent-status waits. Tests cover formatting, missing inputs, and quoting.
BDD assertion steps and validation tests/bdd/steps/assertion_steps.go, tests/bdd/steps/steps_test.go	Registered and implemented the new assertions. Tests verify explicit namespace, context, timeout, target-specific errors, and output isolation.
Feature migration and DSL documentation tests/bdd/features/*.feature, tests/bdd/PLAN.md	Replaced repeated raw kubectl readiness checks with the new BDD steps and documented the assertions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to f68b0

The PR improves BDD Kubernetes readiness assertions and passes the supplied checks; no actionable merge-blocking risk remains. Two EKS scenarios retain the older raw wait form, which is a localized consistency follow-up rather than a product or deployment risk.

Replace the remaining duplicate backend waits.

Lines 381-382 and 419-420 still run the same raw kubectl wait command. Replace both blocks with the NVCFBackend assertion. This keeps timeout handling and failure reporting consistent across the feature.
