k8s-deploy/.github/workflows/run-integration-tests-namespace-optional.yml

# This workflow is inspired by `run-integration-tests-bluegreen-ingress.yml` and introduces namespace-specific testing for manifests.
# It ensures deployments respect manifest-defined namespaces and tests deployments to multiple namespaces.
