April 2026 performance summary for giantswarm/cluster-test-suites: Modernized Hello-World deployment tests by migrating to HelmRelease with OCIRepository, aligning test workflows with platform deployment standards and reducing chart-operator errors. Implemented flexible, provider-specific values management through template files and a parseValuesFile helper. Replaced chart source from HelmRepository to OCIRepository, and migrated to unstructured HelmRelease objects to drop the helm-controller dependency. Added StorageNamespace configuration on HelmRelease to prevent org namespace not found issues. Addressed critical OCI issues (registry URL and chart name) to ensure reliable chart resolution. Result: more reliable end-to-end tests, fewer chart-operator related failures, and streamlined maintenance aligned with Flux CD workflows.
