…t_wffc.py (#4368)

Use DataSource instead of artifactory in test_wffc.py

https://redhat.atlassian.net/browse/CNV-83360

Currently, most storage tests use import from HTTP as the default method to deploy DataVolumes/VMs.

Switching to golden images (except for tests that explicitly validate the import workflow) will improve test stability and reduce flakiness.

Acceptance criteria:

Update storage tests to use golden image as the default deployment method.

Keep HTTP import only for tests explicitly covering import functionality.

In test_wffc.py the tests are using HTTP to create DVs which can make them fail when the requrest for the image is unsuccessful.

Don't hold out on critisism, I'm new and I want to get better.

  • Tests
  • Switched storage tests to use RHEL images and updated VM memory to match RHEL.
  • Replaced external-image/template workflow with a blank-source DataVolume flow and added reusable blank DV and DV-template fixtures.
  • Consolidated storage-class selection into a single module-scoped fixture and improved virtctl/upload wiring.
    • Simplified runtime waiting and VMI status handling.
  • Removed two obsolete registry/clone tests and updated affected test parametrization.

Test execution plan request details

CRITICAL: You MUST post an inline review comment on the first changed line of the first file.
The inline comment should contain the Test Execution Plan with the smoke tests recommendation.
Do NOT submit a formal review - just post the inline comment directly.

As an expert software testing engineer, analyze all modified files in this PR and create a targeted test execution plan.
You will post an inline review comment with the test execution plan on the first changed file.
If you fail to run or post a comment, retry.

Analysis Requirements:

  1. Examine code changes in each modified file
  2. Identify affected code paths, functions, and classes
  3. Analyze pytest-specific elements: fixtures (scope, dependencies), parametrization, markers, conftest changes
  4. Trace test dependencies through imports, shared utilities, and fixture inheritance
  5. Detect new tests introduced in the PR
  6. Smoke Test Impact Analysis: Determine if any changes could affect smoke tests by checking:
    • Changes to files/functions used by tests marked with @pytest.mark.smoke
    • Changes to fixtures or utilities imported by smoke tests
    • Changes to conftest.py files that may affect smoke test execution
    • Changes to core infrastructure code (utilities/, libs/) that smoke tests depend on

Your deliverable:
Your change request comment will be based on the following requirements:

Test Execution Plan

  • Run smoke tests: True / False (Based on your smoke test impact analysis - True if any changes may affect smoke tests)
  • path/to/test_file.py - When the entire test file needs verification
  • path/to/test_file.py::TestClass::test_method - When specific test(s) needed
  • path/to/test_file.py::test_function - When specific test(s) needed
  • -m marker - When specific marker(s) can be used to cover multiple cases.

Guidelines:

  • Include only tests directly affected by the changes
  • Use a full file path only if ALL tests in that file require verification
  • Use file path + test name if only specific tests are needed
  • If a test marker can cover multiple files/tests, provide the marker
  • Balance coverage vs over-testing - Keep descriptions minimal

Hardware-Related Checks (SR-IOV, GPU, DPDK):

When PR modifies fixtures for hardware-specific resources:

  • Collection Safety: Fixtures MUST have existence checks (return None when hardware unavailable)
  • Test Plan: MUST verify both WITH and WITHOUT hardware:
    • Run affected tests on cluster WITH hardware
    • Verify collection succeeds on cluster WITHOUT hardware

CRITICAL WORKFLOW COMPLETION RULES:

When responding to this test execution plan request, you MUST follow these rules EXACTLY:

  1. YOUR ONLY DELIVERABLE: Post an inline review comment containing the test execution plan on the first changed line
  2. THEN STOP IMMEDIATELY - Do NOT generate any additional response
  3. FALLBACK ONLY: If submitting the review fails after retrying, post as a regular PR comment
  4. SILENCE = SUCCESS: After successfully submitting the review, your task is complete. No confirmation needed.

ABSOLUTE PROHIBITIONS (violating these creates empty/meaningless reviews):

  • ❌ Do NOT post acknowledgment messages like "Test execution plan posted", "Review posted successfully", "I've successfully posted"
  • ❌ Do NOT mention review IDs, URLs, or confirmation of posting in the PR thread
  • ❌ Do NOT add any follow-up comments after submitting the review
  • ❌ Do NOT reply to confirm task completion
  • ❌ Do NOT explain what you did - just do it and stop

Remember: The pull request review is visible to users. Additional comments are redundant noise.

CRITICAL: Before setting "Run smoke tests: True", you MUST use shell scripts to:
- Trace the actual fixture dependency chain from smoke tests to changed fixtures
- Verify that smoke tests actually import/use changed utilities or functions
- Confirm the dependency path exists; do NOT assume based on scope or semantics
- Be conservative: Session-scoped fixtures or infrastructure-sounding names do NOT
automatically mean smoke test impact. Only flag smoke test impact when you can
demonstrate a concrete dependency path.
WRONG: "This session-scoped storage fixture might affect smoke tests"
RIGHT: "Smoke test X uses fixture Y, which depends on the changed fixture Z"

Timestamp: 2026-01-25T13:18:26.819Z
Learning: In the openshift-virtualization-tests repository, user jpeimer prefers to avoid nitpicky style changes (e.g., removing `.keys()` from dict membership checks) because verifying every change is expensive. Be cautious about suggesting low-impact stylistic improvements that require verification overhead.

Learning: In the openshift-virtualization-tests repository, when responding to test execution plan requests from openshift-virtualization-qe-bot-3, CodeRabbit must post ONLY an inline review comment on the Files Changed tab and then stop immediately without generating any follow-up comments in the PR discussion thread. No acknowledgment messages, no confirmation of posting, no explanation - silence after posting the inline review equals success. Additional comments create empty/meaningless reviews that clutter the PR.

Learning: In the openshift-virtualization-tests repository, when responding to test execution plan requests from openshift-virtualization-qe-bot-3, do NOT use "REQUEST_CHANGES" review type if the PR author has already marked the PR as verified (e.g., with `/verified` command). Test execution plans are informational guides, not blocking requirements. Use COMMENT event for informational test plans, or only REQUEST_CHANGES if there are actual code issues that need to be addressed before merging.

Learning: In the openshift-virtualization-tests repository, user rnetser prefers to keep refactoring PRs (like PR `#2469`) strictly focused on moving/organizing code into more granular modules without adding new functionality, error handling, or behavioral changes. Such improvements should be handled in separate PRs.

Learning: In the RedHatQE/openshift-virtualization-tests repository, when reviewing any PR with "Quarantine" in the title or a `quarantine` label, always verify compliance with docs/QUARANTINE_GUIDELINES.md:
- Category 1 (Product Bug): must use `pytest.mark.jira("CNV-XXXXX", run=False)` — the `pytest_jira` plugin conditionally skips the test when the Jira issue is open. Do NOT suggest replacing this with `xfail`.
- Category 2 (Automation Issue): must use `pytest.mark.xfail(run=False, reason=...)` — pytest itself handles the skip.
Flag any quarantine PR that uses the wrong category marker, is missing a Jira ticket reference, or uses `run=False` in the wrong context. Raising these compliance questions is always appropriate for quarantine PRs, even if the final resolution confirms the marker is correct.

File: tests/network/upgrade/test_upgrade_network.py:166-177
Timestamp: 2026-03-19T10:37:02.008Z
Learning: In the openshift-virtualization-tests repository, unused fixture parameters in test methods (e.g., `bridge_on_one_node` in `tests/network/upgrade/test_upgrade_network.py`) that exist purely for pytest dependency ordering should not be flagged for removal, and no follow-up issues need to be opened for them. This is an intentional pattern, consistent with the analogous convention for fixture definitions in this codebase.

Learning: In RedHatQE/openshift-virtualization-tests, STD (Standard Test Definition) PRs intentionally use placeholder Polarion IDs (e.g., `pytest.mark.polarion("CNV-00000")`) while test scenarios are still being agreed upon. Real Polarion IDs are filled in before or during the implementation PR. Do not flag placeholder Polarion IDs as a blocking issue in STD PRs that set `__test__ = False`.

Learning: In the openshift-virtualization-tests repository, when determining smoke test impact for test execution plans, only set "Run smoke tests: True" if there is a verified, traceable dependency path from smoke tests to the changed code. Session-scoped fixtures or infrastructure-sounding changes do NOT automatically imply smoke test impact - the dependency chain must be explicitly verified using shell scripts before recommending smoke test execution.

File: conftest.py:333-333
Timestamp: 2025-12-16T20:11:03.645Z
Learning: In the openshift-virtualization-tests repository, when determining smoke test impact for changes affecting py_config["os_login_param"], follow this verification methodology: (1) Find all smoke tests: `rg "pytest.mark.smoke" --type=py -B2 | grep "def test_"`, (2) For each smoke test file, search for VM creation patterns: `rg "VirtualMachineForTests|running_vm|VirtualMachineForTestsFromTemplate|wait_for_ssh|check_ssh_connectivity"`, (3) Trace the dependency chain: smoke test → VirtualMachineForTests/running_vm() → wait_for_ssh_connectivity() (default enabled) → vm.login_params property → py_config["os_login_param"][vm.os_flavor], (4) Check utilities/virt.py for login_params usage: `rg "os_login_param|login_params" utilities/virt.py -C3`. Any smoke test creating VMs with default SSH connectivity checks (running_vm with check_ssh_connectivity=True) depends on os_login_param, even if the test doesn't directly reference it.

Learning: In the openshift-virtualization-tests repository, when conftest.py or utilities/bitwarden.py changes affect py_config["os_login_param"], smoke test impact must be determined by: (1) finding all smoke tests using `rg "pytest.mark.smoke"`, (2) checking each for VM creation patterns (VirtualMachineForTests, running_vm, VirtualMachineForTestsFromTemplate), (3) tracing whether running_vm is called with default check_ssh_connectivity=True, which accesses vm.login_params property that reads py_config["os_login_param"][vm.os_flavor]. The dependency chain is: smoke test → VM creation → running_vm → wait_for_ssh_connectivity → vm.login_params → os_login_param. Any smoke test creating VMs with SSH connectivity (the default) depends on os_login_param.

Learning: In the openshift-virtualization-tests repository, pytest fixtures that declare other fixtures as parameters purely for dependency ordering (without referencing them in the function body) should not be modified to silence Ruff ARG001 warnings. This is an idiomatic pytest pattern for ensuring setup order, and the team prefers to leave such fixtures unchanged rather than adding defensive comments or code to suppress linter warnings.

NEVER submit test implementation without prior STD review. STD and implementation MAY be in the same PR if STD is clearly separated and reviewed first.

Learning: For PRs that only remove or modify pytest markers (like removing pytest.mark.post_upgrade) without changing test logic in openshift-virtualization-tests, collection verification using `pytest --collect-only` is sufficient.

Learning: In the RedHatQE/openshift-virtualization-tests repository, when introducing STD (Standard Test Definition) PRs that define test case structure without implementation, it's acceptable and intentional to use `__test__ = False` to block pytest collection until the tests are fully implemented in a follow-up PR. The STD workflow involves: (1) defining test structure, markers, and documentation first, (2) implementing the actual test logic and removing the collection blocker in a subsequent PR.

Learning: In OpenShift Virtualization mass machine type transition tests, the machine type glob pattern "pc-q35-rhel8.*.*" is intentionally hard-coded in the kubevirt_api_lifecycle_automation_job as it's used only once for this specific test case, with plans to update it in the future if the job needs to support other machine types.

Learning: In the RedHatQE/openshift-virtualization-tests repository, CentOS preferences follow the format "centos-stream<version>" (e.g., "centos-stream9", "centos-stream10"). The generate_instance_type_centos_os_matrix function correctly uses regex to extract numeric versions and constructs the latest version string in the same format as the input preferences for proper comparison.

Learning: In the openshift-virtualization-tests repository, `get_dv_size_from_datasource()` (from `utilities.storage`) does not require a `None`-guard on its return value when the datasource argument comes from a fixture that uses `ensure_exists=True` (e.g., `fedora_data_source_scope_module`). Such fixtures guarantee the datasource exists and has a valid size. Other usages across the repo follow the same pattern without None checks, so do not flag this as a missing fail-fast guard.

Learning: In the OpenShift Virtualization test suite (tests/virt/cluster/common_templates/utils.py), DataSource objects are pre-deployed on the cluster and validated after deployment to ensure they have source in their spec. Therefore, `data_source.source` is guaranteed to exist when checking `data_source.source.exists` in the `get_matrix_os_golden_image_data_source` function, making null-checks unnecessary.

Learning: In the openshift-virtualization-tests repo, large fixture refactoring efforts like the golden image data source migration are handled incrementally by directory/team ownership. The virt/cluster directory is handled separately from virt/node, tests/infra, tests/storage, etc., with each area managed by relevant teams in follow-up PRs.

Learning: In the openshift-virtualization-tests repo, PR `#2199` depends on PR `#2139` which adds the OS_FLAVOR attribute to the Images.Cirros class, making Images.Cirros.OS_FLAVOR available for conditional logic in tests.

Learning: In tests/infrastructure/golden_images/test_common_templates_data_volumes.py, when set_storage_class is True but get_diff_storage_class_from_matrix returns None (indicating only one storage class is available), the test should continue using the default storage class rather than being skipped. This covers special cluster architectures that only have a single storage class available.

Learning: In test_ocs_virt_default_storage_class in tests/install_upgrade_operators/product_install/test_install_openshift_virtualization.py, consecutive_checks_count=3 is sufficient for verify_boot_sources_reimported because datasources update quickly in the installation lane scenario after storage class changes.

Timestamp: 2025-10-16T12:47:04.521Z
Learning: In openshift-virtualization-tests repository, DataVolumes in the openshift-virtualization-os-images namespace are volatile resources managed by DataImportCron. They can be created/destroyed between must-gather collection listing and file retrieval, requiring FileNotFoundError exception handling in test_crd_resources to skip these volatile resources gracefully while still validating DataVolumes in other namespaces. There is no pytest_generate_tests hook that filters out datavolumes from test parametrization.

Learning: In PR `#1723`, the user rnetser clarified that updating downstream string comparisons to handle DataVolume enums from StorageClassConfig is not part of the current PR scope, which focuses only on adding conformance storage class support.

Learning: In the openshift-virtualization-tests repo, PR `#2199` depends on PR `#2139` which adds architecture-specific OS_FLAVOR attributes to the Images.Cirros class (OS_FLAVOR_CIRROS for x86_64/ARM64, OS_FLAVOR_FEDORA for s390x), enabling conditional logic based on the underlying OS flavor in tests.
