# Render app charts on their defaults plus injected cluster/namespace values.
# helm-unittest renders only templates selected by a suite; this smoke check
# also reaches templates with no assertions. It checks rendering, not Kubernetes
# schema validity or runtime behavior. See testdata/render-fixtures/README.md.
