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"

BODY="## Test Execution Plan

- **Run smoke tests: False**
  - Changes to \`utilities/console.py\` add a new \`kubeconfig\` parameter to console functions (new capability, not modifying existing signatures used by smoke tests).
  - \`write_file\` in \`utilities/storage.py\` is used only by CCLM/storage-migration/OADP fixtures — no confirmed dependency chain to any \`@pytest.mark.smoke\` test.

### Tests to run:

- \`-m cclm\` — covers all cross-cluster live migration tests including new boot_id verification and post-migration validation tests
- \`tests/storage/vm_export/test_vm_export.py\` — conftest and constants were modified
- \`utilities/unittests/test_console.py\` — new unit tests for console utility changes"

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, 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 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.

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: 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. Full test execution is not required to verify marker-only changes.

Learning: In the openshift-virtualization-tests repository, when posting test execution plan inline review comments using GitHub API, the full test execution plan content must go in the `comments[].body` field (which appears on Files Changed tab), NOT in the top-level `body` field (which appears in PR discussion thread). The top-level `body` field should be omitted or left empty to avoid posting redundant comments in the PR discussion thread.

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: The test execution plan for PR `#1904` focuses on cluster-type conditional logic where nmstate functionality is bypassed on cloud clusters (Azure/AWS) but fully functional on bare-metal/PSI clusters, requiring different test strategies for each environment type.

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 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.

Timestamp: 2026-02-19T15:36:12.585Z
Learning: In cross-cluster live migration (CCLM) tests in tests/storage/cross_cluster_live_migration/utils.py, boot time verification uses console-based access (get_vm_boot_time_via_console) because SSH connectivity to VMs in the remote cluster is not available. In contrast, storage migration tests in tests/storage/storage_migration/utils.py use SSH-based access (get_vm_boot_time) since VMs remain in the same cluster. This difference in access methods justifies having separate verify_vms_boot_time_after_migration and verify_vms_boot_time_after_storage_migration functions.

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.

Learning: In tests/storage/cross_cluster_live_migration/utils.py, the `parse_boot_time_from_console_output` function intentionally uses minute-level precision (matching `who -b` output like "system boot YYYY-MM-DD HH:MM") for boot-time comparison in CCLM tests. This is acceptable because a file-write operation is performed on each VM between initial boot and migration start, making it practically impossible for the full migration cycle to complete within the same minute as the initial boot. Do not flag minute-level precision as insufficient for boot-time comparison in this context.

Learning: In the openshift-virtualization-tests repository, when configuring SSH on VMs for IPv6 single-stack clusters, use cloud-init's `cloud-init-per always <id> <command>` utility in runcmd (not bootcmd) to restart SSH on every boot. This ensures the command runs after network configuration is applied during cloud-init's proper phase, avoiding early-boot timing issues that prevent guest agent connection.

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.

Timestamp: 2025-06-23T19:18:12.275Z
Learning: In OpenShift Virtualization machine type transition tests, the kubevirt_api_lifecycle_automation_job updates VM machine types to the latest version based on a MACHINE_TYPE_GLOB pattern, and subsequent fixtures may intentionally revert the machine type to test bidirectional transition behavior.
