Verified finding against current doc: "protection to work regardless of a VM's power state or storage configuration" overstated coverage -- this STP only tests WFFC-binding-mode StorageClasses across block and filesystem volume modes, not storage configuration generally. Reworded to scope the claim to VM power state and WFFC vs Immediate volume binding, and made the closing sentence explicit about block/filesystem volume modes and WFFC StorageClass DataVolumes. Signed-off-by: Adam Cinko <acinko@redhat.com>
Verified finding against current doc: the running-VM WFFC scenario only checked data integrity (no binding-mode assertion at all), and the stopped-VM WFFC scenario said "correct storage binding" without defining an observable pass condition. Added an explicit check that the restored PVC/PV binds through the configured WaitForFirstConsumer StorageClass to both, while retaining the existing data-integrity and startup checks. Left the topology-zone assertion scoped to the existing P2 scenario only, as instructed. Signed-off-by: Adam Cinko <acinko@redhat.com>

Address Jose's and Ruth's review comments on PR RedHatQE#146: - Known Limitations mixed in Out-of-Scope, Test Environment, and Risk content (Jose x3, Ruth L77). Trimmed to the one genuine product limitation (DataMover requirement); removed the CSI-only clause (duplicates existing Out-of-Scope item), the StorageClass-dependent bullet (duplicates Test Environment), and the PR #162 bullet (duplicates the Resource Constraints risk). - Acceptance Criteria included a test-strategy detail, not a user outcome (Jose, Ruth L60); removed, already correctly stated under Test Strategy -- Automation Testing. - API Extensions listed internal test-harness utility function names, which the guidelines explicitly forbid (Ruth L99); removed. - Scalability NFR dismissed scale testing as out of scope without acknowledging the underlying OADP/Velero mechanism's own scale constraints, which AGENTS.md requires even when no new scale requirements are introduced (Ruth L69); added acknowledgment. - Verified against the tests repo: Ruth confirmed the multi-namespace Out-of-Scope rationale ("already covered") is false -- test_restore_multiple_namespaces only covers a running VM with no WFFC. Reworded with an honest rationale (genuinely untested, deferred) instead of the incorrect "already covered" claim. Signed-off-by: Adam Cinko <acinko@redhat.com>
…tail Per Adam's decisions on Ruth's review: - Multi-zone is guaranteed on test clusters. Updated Test Environment (Cluster Topology) to state multi-node, multi-zone explicitly, and removed the now-stale single-zone skip condition from Topology Considerations (I.3) -- resolves the L270/L334 contradiction between the P2 topology-zone scenario's implicit assumption and the prior skip-condition language. - The two P0 failure-path goals need a concrete failure-injection mechanism before they're automatable (L126). Added an implementation note deferring that mechanism design to the STD rather than removing or watering down the goals. Still open, pending Adam's own check of the full (untruncated) review comment: L128, whether the stopped-VM+WFFC scenario's backup step (of an already-bound DataVolume) meaningfully exercises WFFC's deferred binding, versus only the restore+start step doing so. Signed-off-by: Adam Cinko <acinko@redhat.com>
Per Adam's decisions on Ruth's remaining review comments: - L129: enumerated the four test configurations explicitly instead of the vague "all new test configurations". - L248: tightened the OADP entry criterion to a concrete, verifiable check (OLM install + sample backup/restore smoke test) instead of the vague "installable and functional". Still open, pending Adam's own review of the full (untruncated) GitHub comments: L57 (VM spec/DataVolume metadata acceptance criterion) and L128 (whether backing up an already-bound WFFC DataVolume meaningfully exercises deferred-binding behavior). Signed-off-by: Adam Cinko <acinko@redhat.com>
Address the remaining open review comments on PR RedHatQE#146 (rnetser, coderabbit): - L57 acceptance criterion: the stopped-VM "spec/DataVolume metadata match the original" wording was not a clean pass/fail. Enumerate the attributes that must survive restore unchanged (CPU/memory, network interfaces, DataVolume size, StorageClass, volume mode) and state explicitly that Velero-injected changes (UID/resourceVersion, restore-tool labels/ annotations, status) are expected and excluded from the comparison. Aligned the two stopped-VM scenarios (III) with the same fields. - L126 P0 failure-path goals: define the observable pass/fail at the STP level -- Backup/Restore ends in a non-successful phase (PartiallyFailed or Failed) carrying a failure condition, plus a post-run orphaned-resource check (Backup, VolumeSnapshot/VolumeSnapshotContent, DataUpload). The injection mechanism stays deferred to the STD per the implementation note. Aligned the two failure-path scenarios (III) accordingly. - L128 WFFC deferred binding: added a WFFC binding note clarifying that CDI's import populator binds the source PVC at import time regardless of WaitForFirstConsumer, so the stopped-VM WFFC scenario exercises deferred binding on restore-and-start (restored PVC stays Pending until the VM's virt-launcher pod schedules), not at backup time. CodeRabbit L323 (observable WFFC storage-binding checks) was already addressed in the current scenarios and needs no further change. Signed-off-by: Adam Cinko <acinko@redhat.com>

23-23: HIGH — Remove test-coverage details from Feature Overview.The overview still says stopped VMs and WFFC are not covered by existing Velero test coverage. That is QE implementation context, not customer value. Keep the customer impact and GA phase here. Move the coverage-gap statement to Motivation or Scope.
As per coding guidelines, Feature Overview sections must explain customer value, state the feature phase, and avoid implementation details.
Source: Coding guidelines
68-68: MEDIUM — Add the missing scalability exclusion.The Scalability NFR points to Section II.1 Out of Scope, but that section has no scalability or scale-testing item. Add a dedicated exclusion with rationale and PM/Lead agreement, or remove the dangling reference.
As per coding guidelines, NFRs must address required categories explicitly, and out-of-scope items must include rationale and dated agreement.
Source: Coding guidelines
77-77: HIGH — Replace every sign-off placeholder before approval.The STP still contains
[PM name/date]and[Name/Date]in Known Limitations, Out of Scope, Test Limitations, and Risks. Replace each placeholder with the responsible person’s name or role and date, or record a dated agreement that the item is excluded.As per coding guidelines, approved STPs must not retain placeholders, and real limitations and risks require dated sign-off.

60-60: HIGH — Make the WFFC test environment reproducible.The plan defers the WFFC
StorageClass,VolumeSnapshotClass, provisioners, and topology details. It also usesOCP 4.23+and does not pin compatible OADP, Velero, or DataMover versions. Define the approved platform and configuration matrix, then record Storage Ecosystem approval.As per coding guidelines, test environments must include explicit versions, a specific storage class, platform, and special configurations.
Also applies to: 227-227
Source: Coding guidelines
127-127: HIGH — Define the failure-injection contract before automation.The P0 scenarios include unavailable OADP/DataMover and corrupted snapshots, but this note defers the injection mechanism to the STD. The document also states that all scenarios are reproducible. Define a non-destructive injection method, or move the unsupported case to Out of Scope with rationale and dated agreement.
As per coding guidelines, STPs must be concise and actionable, and untestable items require documented rationale and agreement.
Source: Coding guidelines
129-129: HIGH — Make the P2 topology assertion controllable.The note explains that virt-launcher scheduling triggers WFFC binding, but it does not define how the source zone is captured or how restore scheduling is constrained to that zone. The P2 scenario therefore compares the bound PV with an undefined
source zone. Define these checks, or assert only a zone outcome that the test controls.As per coding guidelines, acceptance criteria and test scenarios must use observable pass/fail conditions.

The P0 backup-failure goal's cleanup criterion enumerates internal resources (Backup, VolumeSnapshot/VolumeSnapshotContent, DataUpload) — this is implementation detail that AGENTS.md keeps out of STPs. It also reads as self-contradictory: the Backup record is what you'd inspect to assert the failure phase, yet it's listed among resources that must not remain.
Suggest stating the pass criterion in user-observable terms (e.g. "the backup fails clearly and leaves no leftover backup artifacts behind") and deferring which specific resources to retain/clean to the STD. Same applies to the mirrored scenario at L311.

Good catch — agreed the enumeration was both too implementation-specific and self-contradictory (the Backup record is what we inspect to assert the failure phase, yet it was listed among resources that must not remain). Reworded the P0 goal and the mirrored Section III scenario to the user-observable outcome: the failed backup "leaves no leftover backup artifacts behind," with the specific artifacts to check deferred to the STD. The failure-phase + surfaced-condition assertion (which inspects the Backup) stays, and I aligned the Implementation note to "a post-run check for leftover artifacts."

The Functional Testing details describe a single universal flow ("each scenario creates a VM, writes data, performs backup, deletes resources, restores, and verifies data integrity and VM operability") — but this is wrong for 3 of the 8 scenarios: the two P0 failure-path scenarios stop at a failed Backup/Restore, and the P2 topology scenario doesn't follow the delete-then-restore data-integrity flow.
Suggest describing the positive backup/restore workflow separately from the failure-path and topology scenarios, each with its own setup and observable outcomes.
Assisted-by: PI (claude-opus-4-8)

Agreed — the single universal flow was wrong for the failure-path and topology scenarios. Split the Functional Testing details into three workflow shapes: (1) positive backup/restore for the five functional scenarios (create → write data while running → stop if applicable → backup → delete → restore → confirm power state → start → verify data), (2) failure-path for the two P0 negative scenarios (drive to the injected failure, assert observable failure with no leftover artifacts, no delete-restore-verify step), and (3) topology for the P2 scenario (restore → start → assert zone-consistent binding).

This use case claims migration "between clusters or namespaces" with "storage topology preserved," and L47 claims storage-locality preservation — but the plan is explicitly scoped to single-namespace restores (multi-namespace is Out of Scope, L148) and defines no cross-cluster/cross-namespace scenario. Per AGENTS.md, claims in requirements/use cases need matching goals and Section III scenarios.
Suggest narrowing the use case to same-cluster / same-namespace disaster recovery, or adding scenarios that cover the claimed migration path.

Agreed — there is no cross-cluster/cross-namespace scenario, and multi-namespace is explicitly Out of Scope. Narrowed this use case to same-cluster/same-namespace DR ("back up and restore VMs using WFFC StorageClasses within the same cluster and namespace…"), and reframed the adjacent multi-zone use case (L47) from "preserve storage locality / correct topology zone" to zone-consistency with the scheduled node, matching the topology change below.

This acceptance criterion ("Data written to a stopped VM before backup is present after restore") is ambiguous — data can't be written to a powered-off VM. It should state that data is written while the VM is running, then the VM is stopped before backup, so the test actually proves the source VM was stopped at backup time.

The requirement says restore must recreate a stopped VM, but the acceptance criterion and the matching Section III scenarios only verify the VM "can be started." A restore that incorrectly auto-starts the VM would still pass — so preservation of the powered-off state (the whole point of the template / maintenance-window use cases) isn't actually tested.
Suggest asserting the VM is powered off immediately after restore, then explicitly starting it and validating data. Apply the same ordering to both stopped-VM P0 scenarios and the stopped-VM WFFC scenario.
Assisted-by: PI (claude-opus-4-8)

Agreed — "can be started" didn't assert the restored VM is actually powered off. Updated the acceptance criterion to "Stopped VM is restored in the powered-off state (not auto-started), and can then be explicitly started successfully," and applied the same powered-off-then-start assertion to both stopped-VM P0 scenarios (block and filesystem) and the stopped-VM WFFC scenario in Section III.

There was a problem hiding this comment.
This scenario asserts the restored volume's zone matches the source zone ("provisioned in the expected topology zone"; the requirement at L39/L47 and this scenario all treat source-zone preservation as required). However, L60 states zone-topology requirements are still to be confirmed with the Storage Ecosystem team, and source-zone preservation isn't inherently guaranteed for this backup path — so a valid restore that lands the VM and its storage co-located in a different compatible zone would fail this criterion.
Suggest confirming with the Storage Ecosystem / OADP team whether source-zone restore is a real product guarantee. If yes, the scenario must state how the restore is constrained to that zone (otherwise the test is non-deterministic). If no, relax the criterion to zone-consistency with the scheduled VM rather than equality with the source zone.
Assisted-by: PI (claude-opus-4-8)
There was a problem hiding this comment.
Agreed — source-zone equality isn't a confirmed product guarantee (the gaps note under I.Acceptance already flags zone topology as TBC with Storage Ecosystem), and a valid restore landing in a different compatible zone would wrongly fail this assertion. Relaxed to zone-consistency with the scheduled node: the bound PV's zone label matches the scheduling node's zone. Aligned the requirement (I), the P2 use case + goal (II), and this Section III scenario accordingly.

There was a problem hiding this comment.
This NFR is stated in terms of test-harness internals ("existing test timeout thresholds (8-10 minutes per operation)"). Per AGENTS.md, STPs describe user-observable expectations, not the test framework's timeout configuration.
Suggest either stating a justified, customer-facing performance target for backup/restore of a single VM, or removing the timeout-threshold language and deferring it to the STD (consistent with how Performance is already handled as out of scope for this test-debt task).

Agreed — "8-10 minutes per operation" was test-harness internals, and performance is Out of Scope. Reworded the NFR to a behavioral bound ("backup and restore complete without indefinite hangs or timeouts") and deferred concrete duration thresholds to the STD, with a pointer to the Performance out-of-scope note.

"Target: all scenarios automated and integrated into nightly CI before CNV v5.0.0 code freeze" is release-policy/process content. Per AGENTS.md, Test Strategy should describe what is tested and how, not code-freeze timing or delivery process.
Suggest dropping the code-freeze phrasing and keeping the automation description focused on coverage (framework, CI lane, what runs).

Agreed — removed the "before CNV v5.0.0 code freeze" release-process phrasing. The Automation Testing details now stay focused on coverage: tests automated in the existing parameterized framework with Polarion markers, running in the existing nightly CI lane.

The P0 backup-failure goal's cleanup criterion enumerates internal resources (Backup, VolumeSnapshot/VolumeSnapshotContent, DataUpload) — this is implementation detail that AGENTS.md keeps out of STPs. It also reads as self-contradictory: the Backup record is what you'd inspect to assert the failure phase, yet it's listed among resources that must not remain.
Suggest stating the pass criterion in user-observable terms (e.g. "the backup fails clearly and leaves no leftover backup artifacts behind") and deferring which specific resources to retain/clean to the STD. Same applies to the mirrored scenario at L311.

The Functional Testing details describe a single universal flow ("each scenario creates a VM, writes data, performs backup, deletes resources, restores, and verifies data integrity and VM operability") — but this is wrong for 3 of the 8 scenarios: the two P0 failure-path scenarios stop at a failed Backup/Restore, and the P2 topology scenario doesn't follow the delete-then-restore data-integrity flow.
Suggest describing the positive backup/restore workflow separately from the failure-path and topology scenarios, each with its own setup and observable outcomes.

There was a problem hiding this comment.
This use case claims migration "between clusters or namespaces" with "storage topology preserved," and L47 claims storage-locality preservation — but the plan is explicitly scoped to single-namespace restores (multi-namespace is Out of Scope, L148) and defines no cross-cluster/cross-namespace scenario. Per AGENTS.md, claims in requirements/use cases need matching goals and Section III scenarios.
Suggest narrowing the use case to same-cluster / same-namespace disaster recovery, or adding scenarios that cover the claimed migration path.

This acceptance criterion ("Data written to a stopped VM before backup is present after restore") is ambiguous — data can't be written to a powered-off VM. It should state that data is written while the VM is running, then the VM is stopped before backup, so the test actually proves the source VM was stopped at backup time.

The requirement says restore must recreate a stopped VM, but the acceptance criterion and the matching Section III scenarios only verify the VM "can be started." A restore that incorrectly auto-starts the VM would still pass — so preservation of the powered-off state (the whole point of the template / maintenance-window use cases) isn't actually tested.
Suggest asserting the VM is powered off immediately after restore, then explicitly starting it and validating data. Apply the same ordering to both stopped-VM P0 scenarios and the stopped-VM WFFC scenario.

There was a problem hiding this comment.
This scenario asserts the restored volume's zone matches the source zone ("provisioned in the expected topology zone"; the requirement at L39/L47 and this scenario all treat source-zone preservation as required). However, L60 states zone-topology requirements are still to be confirmed with the Storage Ecosystem team, and source-zone preservation isn't inherently guaranteed for this backup path — so a valid restore that lands the VM and its storage co-located in a different compatible zone would fail this criterion.
Suggest confirming with the Storage Ecosystem / OADP team whether source-zone restore is a real product guarantee. If yes, the scenario must state how the restore is constrained to that zone (otherwise the test is non-deterministic). If no, relax the criterion to zone-consistency with the scheduled VM rather than equality with the source zone.

There was a problem hiding this comment.
This NFR is stated in terms of test-harness internals ("existing test timeout thresholds (8-10 minutes per operation)"). Per AGENTS.md, STPs describe user-observable expectations, not the test framework's timeout configuration.
Suggest either stating a justified, customer-facing performance target for backup/restore of a single VM, or removing the timeout-threshold language and deferring it to the STD (consistent with how Performance is already handled as out of scope for this test-debt task).

"Target: all scenarios automated and integrated into nightly CI before CNV v5.0.0 code freeze" is release-policy/process content. Per AGENTS.md, Test Strategy should describe what is tested and how, not code-freeze timing or delivery process.
Suggest dropping the code-freeze phrasing and keeping the automation description focused on coverage (framework, CI lane, what runs).
