[Storage] Add CBT multi-incremental and multi-disk backup tests - #6047
Conversation
📝 WalkthroughWalkthroughCBT fixtures now create configurable blank data disks and sequential backup chains. Utilities calculate VM-wide PVC sizes and resolve guest devices. Tests validate full, incremental, sequential-chain, and multi-disk backups in push and pull modes. ChangesCBT backup-chain and multi-disk coverage
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to This change expands CBT backup-chain and multi-disk test coverage in push and pull modes. Required traceability for the newly active feature tests remains unrecorded, which limits ownership and requirement linkage but presents bounded merge risk. Suggested labels: 🚥 Pre-merge checks | ✅ 6✅ Passed checks (6 passed)

In `@tests/storage/cbt/test_cbt.py`:
- Around line 65-71: Normalize push-mode backup statuses to plain dictionaries
before passing them to assert_backup_status_includes_volumes, matching the
pull-mode current_backup.instance.to_dict()["status"] shape; apply this
consistently to the push-mode assertions at the referenced locations.
In `@tests/storage/cbt/utils.py`:
- Around line 57-62: Update guest_volume_target to handle a missing volumeStatus
value by treating None as an empty collection and returning None, allowing
TimeoutSampler polling in guest_device_path_for_volume to continue instead of
raising TypeError.
- Around line 75-84: Update the guest-device lookup loop around TimeoutSampler
so its TimeoutExpiredError behavior is handled directly: remove the unreachable
fallback raise and the now-unused TimeoutExpiredError import, or catch and
re-raise the sampler exception with volume-specific context. Preserve returning
/dev/{target} when a target is found.

**Test Execution Plan**
**Run smoke tests: True** — Smoke-marked `tests/storage/cdi_clone/test_clone.py` and `tests/storage/cdi_upload/test_upload_virtctl.py` inherit `tests/storage/conftest.py`. The shared conftest imports and calls the changed `utilities/storage.py::write_file_via_ssh` in `snapshot_with_content`.
**Run gating tests: True** — `tests/storage/vm_export/test_vm_export.py::test_vmexport_snapshot_manifests` → `vm_from_vmexport` → `vmexport_from_vmsnapshot` → `rhel_vm_snapshot_with_content` → `rhel_vm_for_snapshot_with_content` → changed `write_file_via_ssh`.
**Affected tests to run**
- `tests/storage/cbt/test_cbt.py::TestFullBackup::test_full_backup_push_mode`
- `tests/storage/cbt/test_cbt.py::TestFullBackup::test_full_backup_pull_mode`

- `tests/storage/cdi_clone/test_clone.py` (smoke)
- `tests/storage/cdi_upload/test_upload_virtctl.py` (smoke)
**Real tests (cluster required)**
Error path: verify privileged writes to data disks, guest-device target polling, and backup PVC sizing for every VM data volume.
`pytest tests/storage/cbt/test_cbt.py::TestMultipleDiskBackup --storage-class-matrix=<valid-storage-class>`
Expected: push and pull backups include the boot disk and both data disks.
Happy path: verify the default non-privileged SSH write path through the VM export fixture chain.
`pytest tests/storage/vm_export/test_vm_export.py::test_vmexport_snapshot_manifests --storage-class-matrix=<valid-storage-class>`
Expected: VM export completes and the target VM contains the fixture test file.

- The STP defines pull-mode integrity validation through data pulled from the exposed endpoint, while this PR validates backup status rather than restored/pulled data. This leaves the pull-mode P1 scenario only partially covered. [::RedHatQE/openshift-virtualization-tests-design-docs::]
- The STP requires pull-mode client-certificate security validation; no corresponding coverage is described in this PR. [::RedHatQE/openshift-virtualization-tests-design-docs::]
- The STP explicitly calls for forced-full, insufficient-storage, alternate StorageClass, concurrent-backup, failure-recovery, hotplugged-disk, migration, and backup/migration-exclusion scenarios. The PR’s new multi-disk and sequential-chain tests do not cover these scenarios; exclusions should be documented with follow-up tracking where applicable. [::RedHatQE/openshift-virtualization-tests-design-docs::]
- Pull mode depends on VMExport to expose the NBD endpoint, so changes to pull-backup fixtures should preserve that integration and its endpoint/security preconditions. [::RedHatQE/openshift-virtualization-tests-design-docs::]

**Test Execution Plan**
**Run smoke tests: True** — `tests/storage/cdi_clone/test_clone.py` and `tests/storage/cdi_upload/test_upload_virtctl.py` inherit `tests/storage/conftest.py`. That shared conftest calls the changed `utilities/storage.py::write_file_via_ssh` from `snapshot_with_content`.
**Run gating tests: True** — `tests/storage/vm_export/test_vm_export.py::test_vmexport_snapshot_manifests` → `vm_from_vmexport` → `vmexport_from_vmsnapshot` → `rhel_vm_snapshot_with_content` → `rhel_vm_for_snapshot_with_content` → changed `write_file_via_ssh`. Storage gating tests also inherit `tests/storage/conftest.py`, which references the changed utility.

**Real tests (cluster required)**
Error path: validate privileged data-disk writes, guest-device discovery, and backup PVC sizing for all VM volumes.
`pytest tests/storage/cbt/test_cbt.py::TestMultipleDiskBackup --storage-class-matrix=<valid-storage-class>`
Expected: Push and pull full backups include the boot disk and all data disks.
Happy path: validate the existing non-privileged SSH write path through the VM export fixture chain.
`pytest tests/storage/vm_export/test_vm_export.py::test_vmexport_snapshot_manifests --storage-class-matrix=<valid-storage-class>`
Expected: VM export completes and the target VM contains the fixture test file.

Implement TestMultipleIncrementalBackups and TestMultipleDiskBackup backup-success tests, replacing their STD placeholders.
What this PR does / why we need it:
Add backup-success coverage for sequential incremental backup chains and multi-disk VMs in both push and pull modes.
completed_push_backup_chainandready_pull_backup_chainfixtures that perform a full backup followed by a configurable number of incremental backups, and use them (with incremental_count 0 or 1) in place of the now-removed single-purpose full/incremental fixtures.vm_with_cbt_labelwith an optionaldata_disk_countto attach and write test data to additional blank data disks before first boot.use_sudotowrite_file_via_sshfor writing to guest paths (e.g. raw block devices) the unprivileged SSH user cannot access directly.Which issue(s) this PR fixes:
Special notes for reviewer:
These tests are scoped to backup success (
includedVolumes/type). The STP uses restore only as a QE integrity check, not as a product feature (known limitation: there is no restore API). Restore-based integrity validation for the implemented P0 scenarios is intentionally excluded from this PR and remains covered by remaining STD placeholders in the same file (Windows, hotplug, concurrent, live-migration).
