test(bundler): assert the DRA node-label warning count, not just its presence - #2465
Merged

Conversation
…presence Review follow-up to NVIDIA#2457. No shipped behavior changes. TestWarnDRAEvictionNodeLabelRequired collected the first matching warning and stopped, so it could not tell a correct single emission from a regression emitting the same warning twice. It now counts every match and asserts an exact total; injecting a duplicate appendWarning fails the cases that previously passed. draEvictionComponentNames collects every matching ref rather than stopping at the first, so a recipe carrying both DRA variants yields one warning per component. No case supplied more than one DRA ref, leaving that loop unexercised - add one that expects two warnings. Also re-wrap an over-long line in the AKS and GKE guides to the surrounding ~72-char register, and drop editorializing phrasing in bundling.md in favor of the neutral reference voice.

Counting warnings is not sufficient on its own. The two-variant case expected two warnings but then inspected only matched[0], so an implementation emitting one component's warning twice and dropping the other's satisfied both the count and the substring check. Add wantOwners: each named component must own exactly one warning. Injecting a loop that emits draNames[0] for every iteration now fails with "nvidia-dra-driver-gpu owns 2 warnings, want exactly 1" and "nvidia-dra-driver-gpu-ocp owns 0 warnings, want exactly 1"; both passed before this change.

The bundler filters disabled components before the warning path runs (recipeResult is reassigned to the enabled-only set), so a resolved recipe never carries both DRA variants. Verified on a real OCP composition: the raw builder result yields [nvidia-dra-driver-gpu nvidia-dra-driver-gpu-ocp], but the filtered result the bundler actually passes yields only [nvidia-dra-driver-gpu-ocp], because the OCP overlay sets the generic component to enabled: false. The row therefore modeled a state production cannot produce. Remove it along with wantOwners and its assertion loop, which existed only to serve it. The count assertion stays and still covers the reachable regression: injecting a duplicate appendWarning fails the single-component cases. Also drop an unsupported frequency claim from bundling.md - NVIDIA#2456 records one observed upgrade plus node lifecycle as the durable risk, which does not establish that upgrades are the most common path.

Summary
Review follow-up to #2457, addressing the comments left on that PR after it merged. No shipped behavior changes — the production warning path is correct as merged; this closes a test blind spot and two documentation nits.
One reviewed suggestion is deliberately absent. The proposal to cover the two-DRA-variant warning path was implemented, then removed once it turned out to be unreachable: the bundler swaps in the enabled-only component set before the warning path runs, and the OCP overlay disables the generic DRA component, so production only ever sees
nvidia-dra-driver-gpu-ocp. Reasoning and the measured evidence are under Motivation below, so it does not need reconstructing from the review thread.Motivation / Context
Five review comments landed on #2457 shortly before it merged, so none were addressed in that PR. Three were actionable; two the reviewer resolved themselves.
The test could not detect a double-emit.
TestWarnDRAEvictionNodeLabelRequiredscannedb.warningsfor the first entry matchingkubelet plugin only on nodes labeled, assigned it, andbreaked. Presence was asserted; count never was. A regression emitting the same warning twice for one component would have passed.Not a live defect. One DRA component yields one warning, which is what happens now; the gap is detection of a future regression, not current behavior.
A review round proposed also covering the multi-component loop, since
draEvictionComponentNamesappends every matching ref rather than stopping at the first. That case was added and then removed: the bundler reassignsrecipeResultto the enabled-only set before the warning path runs, so a resolved recipe never carries both DRA variants. Checked against a real OCP composition — the raw builder result yields[nvidia-dra-driver-gpu nvidia-dra-driver-gpu-ocp], but the filtered result the bundler passes yields only[nvidia-dra-driver-gpu-ocp], because the OCP overlay sets the generic component toenabled: false. The loop is unreachable withlen > 1, so the case modeled a state production cannot produce.Related: #2456, #2457.

Component(s) Affected
pkg/bundler(tests only)docs/user/bundling.md,docs/integrator/aks-gpu-setup.md,docs/integrator/gke-gpu-setup.mdImplementation Notes
Count assertion. The scan collects all matching warnings instead of the first. A
wantCountfield defaults to 1 (the single-component case) so existing rows need no change, and the assertion reports the actual total on failure.Documentation. One line in each of the AKS and GKE guides ran 118 characters inside a paragraph wrapped at 76–78, starting a new sentence at the tail of a soft-wrapped line; both are re-wrapped to the surrounding register. Three phrases in
bundling.md— "worse than uniform failure", "the more dangerous shape", "bites hardest" — are replaced with neutral phrasing that keeps the same claim. The replacement wording asserts no frequency: #2456 records one observed upgrade plus node lifecycle as the durable risk, which does not establish that upgrades are the most common path.Testing
Control, not just a passing test. Injecting a duplicate
b.appendWarning(msg)intowarnDRAEvictionNodeLabelRequiredfailsboth components enabled warnsandconfigured label appears in the warningwithemitted 2 node-label warnings, want 1; both passed before this change. Reverting the injection returns the suite to green. That is the regression the count assertion exists to catch.make qualifywas not run to completion —tools/api-diff_test.shfails in this environment withmktemp: Operation not permitted. The change is test-and-docs only, with no production code touched, so lint and the fullpkg/bundlerpackage are the checks that match the change.Risk Assessment
Minimal. No production code is modified; the diff is one test file and three documentation files. The documentation edits change wrapping and wording, not instructions — every command, label, and path is unchanged.
