📝 WalkthroughWalkthroughThe change adds helpers for Windows node annotation counting and autoscaler manifest generation. It adds an end-to-end test for Windows cluster autoscaling. It adds a test for private-key replacement during Windows MachineSet scaling. It adds a test that recreates Windows nodes with invalid WMCO version annotations and checks workload and load-balancer connectivity. Suggested reviewers: Priority: ➖ Normal Merge Risk: 🟡 Moderate · up to The new serial tests can time out while cluster changes remain active or pass before node recreation is complete, potentially disrupting subsequent test runs. These issues should be fixed before merge. Important Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional. ❌ Failed checks (1 error, 7 warnings)

Full details: Go Best Practices & Build TagsExplanation The pull request introduces error paths that are silently discarded. Resolution Return an error from Full details: Platform-Specific RequirementsExplanation OCP-42047 introduces a vSphere naming violation. The test runs on vSphere because it skips only platform Resolution Use a platform-aware clone name that remains within the vSphere MachineSet limit, and verify the resulting generated machine name before provisioning. Alternatively, skip OCP-42047 on vSphere (and other platforms with the same naming constraint). Document the platform limitation and the reason for the skip or naming rule. Full details: Test Structure And QualityExplanation The pull request introduces many bare Gomega assertions, which violates the explicit assertion-message requirement. In Resolution Add a meaningful diagnostic message to every newly introduced bare assertion. Identify the operation and relevant resource in each message, for example Full details: Microshift Test CompatibilityExplanation The three new serial tests are not protected from MicroShift. The enclosing Resolution MicroShift compatibility notice: These tests use APIs or features that are not available on MicroShift. If this repository's presubmit CI does not already include MicroShift jobs, verify the tests with Full details: Single Node Openshift (Sno) Test CompatibilityExplanation The pull request adds three unprotected Ginkgo tests: OCP-42047, OCP-39640, and OCP-35707. The authoritative diff shows each test changes Windows MachineSet replica counts and waits for node counts to change. OCP-42047 also creates a MachineAutoscaler and validates scale-up and scale-down. OCP-39640 scales the MachineSet down to one node and back to its initial size. OCP-35707 adds a node, later restores the original size, and recreates nodes with invalid WMCO annotations. These are explicit node-scaling or node-recreation assumptions that are not valid for SNO. The enclosing Describe has no approved SNO protection, and none of the three test names or bodies contains the required skip label or topology guard.

In `@ote/test/e2e/utils.go`:
- Around line 2109-2111: Update getNumNodesWithAnnotation to propagate the query
error instead of returning a zero count, and adjust its caller to receive and
handle the returned error while preserving the existing retry/wait behavior for
transient failures.
In `@ote/test/e2e/winc.go`:
- Line 2069: Add the “[Disruptive]” marker to the titles of all three newly
added specs, including the spec identified by OCP-42047, so they are classified
correctly by the test runner. Preserve their existing metadata and do not add
unrequested priority, duration, or other tags.
- Around line 2273-2275: Bound the recreation loop around
getNumNodesWithAnnotation and waitForMachinesetReady with an explicit deadline,
using the updated getNumNodesWithAnnotation signature and the test’s context or
timeout mechanism. Exit when the deadline is reached and assert that the loop
completed successfully, rather than allowing the Ginkgo spec timeout to
terminate it implicitly.
- Line 2202: The OCP-39640 spec must honor its 45-minute Ginkgo timeout and
reliably restore cluster state after cancellation. Update the body waits,
including the final waitWindowsNodesReady call, to observe ctx and fit within
the timeout budget; replace ordinary defers for MachineSet, WMCO, and
cloud-private-key restoration with Ginkgo DeferCleanup callbacks that use
bounded cleanup waits.

These comments are irrelevant to our existing jobs, we do not support MicroShift Nor SNO and disconnected will have a dedicated cluster |

Tip For best results, initiate chat on the files or code changes.
The MicroShift and SNO compatibility warnings do not apply because WMCO does not support those environments. The disconnected-network warning does not apply to the existing jobs because disconnected testing uses a dedicated cluster. I withdraw these warnings. Future reviews will not raise these compatibility notices for WMCO tests.

Create the replacement cloud-private-key Secret before scaling the Windows MachineSet so new machines are configured with the replacement key.

Summary
Migrates three long-duration disruptive OTP tests into OTE for WINC-1973, following the scheduling and restoration patterns from PR #4490.
[Serial][Disruptive][Timeout:45m],SpecTimeout(40m).[Serial][Disruptive][Timeout:55m],SpecTimeout(50m).[Serial][Disruptive][Timeout:50m],SpecTimeout(45m).Files changed:
ote/test/e2e/winc.go,ote/test/e2e/utils.go, and focused unit tests inote/test/e2e/utils_test.go.Scheduling and cluster restoration
Uses both runner timeout tags and Ginkgo spec timeouts, serial scheduling for cluster-wide mutations, captured node counts and MachineSet replica baselines, and safe clone naming/creation. Restoration errors are asserted. OCP-39640 cleanup preserves the dependent LIFO sequence: delete replacement Secret, restore original Secret, restore WMCO replicas, restore MachineSet replicas and readiness, then remove the original-key temporary file.
OCP-42047: Autoscaler pressure and scale-down
The workload requests CPU
2and scales to the observed Windows node count plus one, replacing platform-specific replica counts. The MachineAutoscaler uses minimum 1 and maximum 4 replicas. Scale-down is verified with a bounded poll of desired MachineSet replicas, requiring a return to at most the captured baseline rather than accepting an already-satisfied Ready-replica lower bound. Replica-read errors are returned so the poll can retry.OCP-39640: Key generation, ordering, and focused state assertion
cloud-private-keySecret before MachineSet scale-up."unhealthy":0log assertion with a bounded state poll. Other callers retain their existing log-search behavior.initialReplicasbefore Node reads and Ready/key-hash evaluation. Each selected Node must be Ready and carry the expected replacement public-key hash.This verifies replacement-key adoption and readiness; it does not prove that every original Machine has been physically replaced. The source-level health-log requirement is unreliable, but the precise deployed-build cause of prior failures remains unconfirmed.
OCP-35707 and shared helpers
The annotation recovery loop is bounded and retries read errors. Connectivity, background-check, and LoadBalancer address helpers support the migrated test.
Validation
The latest reviewed commit is
bc8260b43faf021feefae223a3ba0e32867cfc0d. Final local checks passed:make imports,make lint, andmake build-tests-ext.No live-cluster validation of this latest assertion change has completed yet. New-head CI is pending. The aggregate 50-minute spec runtime budget is not proven by local tests; existing waits and restoration remain unchanged. The separate HostProcess log-retrieval change is not included in this PR.
