WalkthroughAdds an extended networking test that creates an assignable node without a host-cidrs annotation. The test applies an EgressIP object and verifies that assignments target only the two real worker nodes. Cleanup now fails on unexpected deletion errors. ChangesEgressIP orphan-node validation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The new EgressIP test verifies that the orphan node is excluded, but it can still pass if both EgressIPs are assigned to one valid node. This weakens coverage of the intended two-node assignment behavior. Caution Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional.

Full details: Test Structure And QualityExplanation The added Ginkgo test has explicit quality violations. Three new error assertions use Resolution Add diagnostic messages to every new error assertion. Use bounded contexts for the node Create and Delete operations. Move orphan-node creation into BeforeEach and cleanup into AfterEach, while preserving idempotent NotFound handling. Keep the existing bounded EgressIP propagation waits. Full details: Single Node Openshift (Sno) Test CompatibilityExplanation The added Ginkgo test assumes a multi-node cluster. Its shared setup skips unless there are at least 3 worker nodes ( Resolution Single Node OpenShift (SNO) compatibility notice: This test assumes a multi-node cluster and may fail on Single Node OpenShift deployments. Verify the test with an additional CI job: Full details: No-Sensitive-Data-In-LogsExplanation The new test adds log output that includes real cluster node names. Resolution Remove or redact real node names from the new logs and assertion messages. Log only non-sensitive counts or fixed test identifiers, and avoid dumping the node-to-EgressIP map. If assignment details are required, use sanitized node labels and confirm that IP values are safe for the test log destination.

@coderabbitai On pre-merge check : I followed the established pattern in the same file — existing tests at lines 146 and 269 log full node names and EgressIP maps via framework.Logf. CI clusters are ephemeral, so node names are non-sensitive hence keeping it that way. |

After checking the upstream PR description wasn't the problem that allocations weren't happening for other nodes?
So there are 5 nodes, one node being wrong was blocking us continuing for other nodes ? this test seems to be doing something different - all assignment logic is possible to test with unit tests right?
would be interesting for you to add why we think we need e2e for this

Yes, so if one node amongst all nodes has issues it stalls others, the unit test covers assignment logic which includes missing, malformed, empty annotation and retry cache.
Right, one bad node blocks controller for other nodes so this tests - the E2E there focuses on does assignment work with an orphan present . There were some recommendations taken to consideration from the coderabbit as well while developing that E2E.
I had an E2E in upstream so I thought to get that to origin as well, but again looking to this with your thoughts I learn and agree that if it's able to cover within unit tests the E2E isn't needed." I'd be turning this PR completely on unit test and would update on that soon. |
@tssurya , Also as it seems the origin doesn't have the coverage/mechanism for unit tests so I'm unsure if I should close this assuming the existing unit tests are sufficient in d/s merge. Please advise and thank you for the thoughts. |

not sure I fully follow, but skimming through your comment:
|
The e2e was appended knowing there is existing e2e to have assurance on fix. There wasn't any gap I found that time that unit test can't cover - in fact I realize it's just a subset of what unit test already covers. In sum, I considered this change to be a functional change ( letting controller to skip the node ) and it gives assurance also satisfies the contributing guidelines on u/s and added e2e there and pulled same to origin here. I'll work to get a QA and thoughts to this and meanwhile will appreciate if you have any more thoughts to it. |

Validate node eligibility with an independent set.
applyEgressIPObject rewrites egressIPSet[eip] with the observed status node before this assertion. Therefore, expectedNode is not the expected worker node. An assignment to nonEgressIPNodeName can pass this check.
Keep the requested EgressIP keys separate. Build a set from egressIPNodesOrderedNames. Assert that every item.Node belongs to that set.

Adds an e2e test that validates the core bug scenario from OCPBUGS-99273: a node with missing host-cidrs annotation must not block EgressIP assignment for the entire cluster. The test creates a bare Node object (no backing ovnkube-node) labeled as egress-assignable, allocates EgressIPs for two real nodes, then verifies: - Both EgressIPs are assigned (controller did not abort) - Each EgressIP is assigned to a valid egress node - Neither EgressIP lands on the orphan node Aligns with the upstream e2e in ovn-kubernetes/ovn-kubernetes#6773 and the flake fix in ovn-kubernetes/ovn-kubernetes#6863.
