The uninstall section promised that no manual cleanup of the TLS Secrets is needed, reversing the instruction it replaced. That promise rests on an ownerReference the operator patches on at reconcile time rather than sets at creation, and two paths skip the patch: a dry-run reconcile returns before it, and a Secret already present under the same name with a mismatched cert-manager.io/certificate-name annotation is counted toward success and returned on unpatched. The deletion finalizer does not cover the gap — it enumerates only the users, internal-<release>, internal-<release>-users and encryption-key Secrets. So a Secret predating the release at one of these names can stay unowned and survive uninstall, and for <release>-ca-cert that orphans the CA private key. State the reconcile-time mechanism and tell operators to confirm the CA Secret is gone. Pin the outcome with a chainsaw step asserting the CR owns all three TLS Secrets on a normal install, so the claim goes red if the operator stops patching instead of rotting as prose. The external-hostname note described a permanently empty _namespace.host as a bootstrap window that self-heals. A tenant with no host of its own and no ancestor supplying one resolves to an empty host for good, leaving external TLS hostname verification silently unavailable. Name that case alongside the transient one, and say why the render is not failed closed: it would break existing hostless tenants already running external access over IP.

Chainsaw E2E tests
The Cozystack E2E app suite, written for Kyverno Chainsaw — a declarative, Kubernetes-native E2E test framework (CNCF, part of the Kyverno project; successor to KUTTL).
This directory replaces the per-app BATS suite that used to live in hack/e2e-apps/*.bats. The CI e2e job runs chainsaw test hack/e2e-chainsaw/ after make install-cozystack; cluster bootstrap (hack/e2e-prepare-cluster.bats, hack/e2e-install-cozystack.bats) and the OpenAPI checks (hack/e2e-test-openapi.bats) remain BATS.

What Chainsaw buys over the BATS suite
- Readable tests — a list of resources and expected states, not shell control flow. The
timeout N sh -ec "until kubectl get ..."+kubectl waitpair that appeared ~100 times collapses into a singleassertthat polls existence and state together. - Distinguishable failure modes — "object never created", "created but never ready", and "wrong status" all surface as a structured diff instead of an opaque shell timeout.
- Automatic diagnostics —
catchblocks dump events,describe, and pod logs on any failure (the BATS suite only did this inharbor.bats, by hand). - Automatic cleanup — resources Chainsaw applied are deleted (and waited on) in reverse order;
finallycovers operator-created leftovers. - CI-ready output — a JUnit
chainsaw-report.xmlis emitted for the test summary.
Test anatomy
Each suite is a directory with a chainsaw-test.yaml (one or more Test docs) plus the manifests it applies. A step has try (operations: apply, assert, error, script, delete, …), optional catch (diagnostics on failure), and optional finally (teardown regardless of outcome).
Declarative suites assert on status.conditions and concrete fields. Inherently imperative suites keep their logic in script steps:
- openbao —
bao operator init/unsealviakubectl exec. - kuberture —
jqon Service annotations + external-dns split-horizon log assertions. - gateway — admission-rejection cases that need
kubectl --asimpersonation or error-message greps; the tenant apex is read from the namespacenamespace.cozystack.io/hostlabel at runtime so they pass on any host. - kubernetes-latest/previous — wrap
_lib/run-kubernetes.sh(Kamaji bringup, port-forward, LB/NFS/ouroboros). The scriptcds to the repo root (the test dir ishack/e2e-chainsaw/<suite>, so repo root is../../..).
Conventions / gotchas (Chainsaw v0.2.15)
- Condition asserts use the filter-as-list form, not the documented
[0]index:Thestatus: (conditions[?type == 'Ready']): - status: "True"(conditions[?type == 'Ready'])[0]: {status: "True"}idiom fails with "field not found in the input object". - A reading of a failure diff: the "actual" side is a projection onto the expected fields —
status: {}means the JMESPath expression failed, not that status is empty. Read the error line above the diff first. errorwith a bare resource ref (name only) asserts the resource does not exist (used for "PVC reclaimed", "no backup schedule", "child has no Gateway HR").scriptruns in the test directory with$NAMESPACEset to the config namespace (tenant-test).
Running locally
Requires a cluster with Cozystack installed and a tenant-test namespace (the environment hack/e2e-install-cozystack.bats produces). bucket additionally needs mc and nc on the host; kuberture/openbao/harbor need jq.
# install chainsaw
go install github.com/kyverno/chainsaw@latest # or: brew install kyverno/chainsaw/chainsaw
# run all suites (config picked up from .chainsaw.yaml)
cd hack/e2e-chainsaw
chainsaw test
# run a single suite
chainsaw test postgres/
kubernetes-latest/kubernetes-previous each bring up a full tenant Kubernetes cluster (~25 min, real worker nodes) and vminstance boots a nested VM — expect a long run for the full set.
CI integration
The e2e job in .github/workflows/pull-requests.yaml runs make -C packages/core/testing test-chainsaw (which execs chainsaw test hack/e2e-chainsaw/ inside the e2e sandbox) and uploads chainsaw-report.xml. The sandbox image (packages/core/testing/images/e2e-sandbox/Dockerfile) ships the chainsaw binary alongside kubectl/helm/mc/jq/nc.
