Addressed in b5e4267. Verified each point before acting. Nitpick, distinguish a failed render from a zero-match selector: valid, and the most important of the three. Mutation-tested both paths. A template error in Nitpick, drop the redundant grep from the default-off assertion: valid, applied. The Major, create the secrets directory: the stated failure mode does not exist. Added the
Full mutation matrix re-run after the change, all four still fail closed: unknown release name, duplicate |
make test failed on the first cassandra case with "no releases found that matches specified selector(name=cassandra)", even though cassandra is declared in 01-dependencies. render_chart_values tried 01-dependencies and fell back to 02-core, but it only passed the gateway state values on the 02-core attempt. global.yaml .gotmpl is shared by every state and marks those values required, so the 01-dependencies attempt failed on the required check, 2>/dev/null discarded that error, and the fallback reported the one thing that was true of 02-core: it does not declare cassandra. Run every invocation against the whole helmfile.d directory with a selector, the way the stack is applied, and drop the fallback and the suppression. Copy the whole stacks tree rather than self-managed alone, because 00-observability-infrastructure includes a sibling stack through a relative path, and seed a per-test environment file for each stack the copy reaches. Two further defects were hidden behind the first failure. The chart validation cases rendered the published chart reference, which fails on a chart pull offline and passed as if the chart had rejected the values; they now render the in-repo chart and assert the both-fields and neither-field diagnostics separately. The neither-field case could never reach that state because base.yaml ships cassandra minAvailable: 2, so it now clears it with the chart's own unset sentinel. Add assert_single_release, which requires every targeted release to resolve to exactly one release in the stack. Zero means it moved or was renamed, more than one means two states declare it. The value assertions also move from whole-file greps to keyed yq lookups, so a match in an unrelated release's block no longer counts.

Why
make testindeploy/stacks/self-managedfailed ontests/pdb-value-wiring.shat the first case:
The message is misleading.
cassandrais declared inhelmfile.d/01-dependencies.yaml.gotmpl, and it was being looked for in02-core.render_chart_valuestried01-dependenciesand fell back to02-core, but itpassed the gateway state values only on the
02-coreattempt.global.yaml.gotmplis shared by every state and marks them required, so thefirst attempt died with:
2>/dev/nulldiscarded that, the fallback ran02-core, and the reported errorwas the second failure rather than the real one. A
||fallback across statefiles cannot tell "this state is misconfigured" apart from "this state does not
own that release", and it reports the wrong one.
Three further defects were sitting behind that first failure:
self-managedto a temp directory, buthelmfile.d/00-observability-infrastructure.yaml.gotmplincludes a siblingstack through
../../observability/helmfile.d/.... The copy was not aworking stack, so the directory could not be rendered as a whole.
helmfile templateagainst the published chartreference. Offline, and with the placeholder registry the test sets, that
fails on a chart pull. Both cases only checked for a non-zero exit, so a
pull failure passed as if the chart's
failhad fired. Verified: without--chartthe error isinvalid reference: invalid repository "YOUR_ORG/YOUR_TEAM/helm-nvcf-cassandra".podDisruptionBudget.enabled: truewith no availability fieldand expected the chart to reject it, but
environments/base.yamlshipscassandra.podDisruptionBudget.minAvailable: 2. The merged values always hadone, the chart rendered fine, and the case could never pass.
What changed
helmfile.ddirectory with aselector, the way
makeapplies the stack. No state file is hand-picked, soa release moving between states cannot break the test. The fallback and the
2>/dev/nullare gone.helmfile_commonarray shared byevery invocation, since
global.yaml.gotmplrequires them regardless of whichrelease is selected.
deploy/stackstree instead ofself-managedalone, and seeds a per-test environment file for each stack the copy reaches,
so the relative sibling include resolves.
deploy/helm/cassandra/helmwith--chartand--skip-deps, following thepattern already used by
check-llm-pki-issuer.sh. They now assert the exactdiagnostic and each rules the other one out, so a chart that collapsed the two
branches into one message would no longer pass both.
minAvailablewith the chart's own unsetsentinel (
""), which is how that chart spells "not set", so it reaches theneither-field state. Confirmed it now hits
poddisruptionbudget.yaml:23while case 4 hits
:20.assert_single_release, which requires every targeted release toresolve to exactly one release in the stack. Zero means renamed, removed, or
looked for in the wrong place. More than one means two states declare it,
which is the failure mode fix(self-managed): declare the LLM PKI issuer in one Helmfile state #951 fixed for the PKI issuer.
helmfileexits non-zero bothwhen a selector matches nothing and when the stack does not render, and
collapsing those two is how this test came to blame a missing release for a
missing gateway value.
assert_single_releaseandrender_chart_valuesnowseparate them and print the underlying helmfile error. The two commands fail
on different classes of defect, because
list --skip-chartsdoes not renderthe release values files and
write-valuesdoes, so both needed the handling.yqlookups. Thewritten values file is the full
global.yaml.gotmplrender, sogrep -A2 podDisruptionBudget | grep enabled: truewas matching any release'sblock, not the one under test.
Customer Release Notes
Not customer visible.
Plan Summary
Test harness only. No chart, state, image, or value defaults change. The stack
itself renders identically before and after.
Usage
Testing
make testfromdeploy/stacks/self-managed, complete output:Exit code 0.
git diff --checkclean.Every guard is mutation-tested, so none of them is vacuous:

Notes
Separate from #951 by design, and it does not touch the PKI duplicate-release
fix. The two branches do not overlap: #951 edits
02-core.yaml.gotmpl,llm-pki-release.sh,check-llm-pki-issuer.shand theMakefile, this oneedits
pdb-value-wiring.shonly. If #951 merges first,make testalso gainscheck-llm-pki-issuer.sh, which passes here.assert_single_releaseoverlaps in intent with the cross-state declarationcheck #951 adds for
nvcf-pki. That is deliberate. Both exist because a releasedeclared in two states is the failure mode this stack keeps hitting.
Review follow-up in b5e4267 covers three CodeRabbit points. Two were valid and
are folded into the description above: separating render failures from
zero-match selectors, and dropping a redundant
grepfrom the default-offassertion. The third, creating the secrets directory before writing the test
secrets file, described a failure mode that does not exist.
deploy/stacks/self-managed/secrets/secrets.yaml.templateis tracked and notgitignored, so the directory is present in any clean checkout and
cp -Rcarries it into the temp tree. The
mkdir -pis in as defence against thattemplate moving later, not as a fix.
