📝 Walkthrough

Walkthrough

Renamed and simplified storage utility API: assert_hotplugvolume_nonexist_optional_restart(vm, restart: bool) → assert_hotplugvolume_nonexist(vm). Tests updated to import and call the new function (removed explicit restart handling).

Changes

Cohort / File(s)	Summary
Tests — hotplug & upgrade tests/storage/test_hotplug.py, tests/storage/upgrade/test_upgrade_storage.py	Updated imports and calls to use assert_hotplugvolume_nonexist(vm) instead of assert_hotplugvolume_nonexist_optional_restart(vm, restart=...). Removed explicit restart argument from three call sites.
Utilities — storage API utilities/storage.py	Replaced assert_hotplugvolume_nonexist_optional_restart(vm, restart: bool = True) with assert_hotplugvolume_nonexist(vm) and removed restart-related logic and messaging.

i see assert_hotplugvolume_nonexist_optional_restart is also used in windows test and in storage upgrade. should the restart be removed there as well?

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

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"

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 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.

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, 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.

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.

Timestamp: 2025-06-23T19:24:28.327Z
Learning: In OpenShift Virtualization machine type transition tests, the test_machine_type_transition_without_restart method with restart_required=false parameter validates that VM machine types do NOT change when the lifecycle job runs with restart disabled, so the assertion should check against the original machine type rather than the target machine type.

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.

File: conftest.py:333-333
Timestamp: 2025-12-16T15:09:49.597Z
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.

The top-level `body` field should be omitted or left empty to avoid posting redundant comments in the PR discussion thread.

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 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.
