Adapt test_metric_kubevirt_vm_disk_allocated_size_bytes to filesystem storageClass

[OhadRevah]

test_metric_kubevirt_vm_disk_allocated_size_bytes fails on filesystem-backed
storage classes (e.g., gcnv-flex on GCP) because get_pvc_size_bytes() returns
the raw PVC capacity while the Prometheus metric reports usable space after
filesystem overhead (~6%).

Modified get_pvc_size_bytes() to check the PVC volumeMode and, when set to
Filesystem, subtract the filesystem overhead from CDIConfig
(per-storage-class lookup with global fallback). Block PVCs remain unchanged.
Updated both Linux and Windows test call-sites to pass the cdi_config fixture.

Summary by CodeRabbit

• Tests
  • Updated disk allocated size metric tests to accept injected storage-config data so expected values account for storage-class or global filesystem overhead. This makes metric expectations more accurate across different storage configurations and improves test alignment with real provisioned VM disk capacities.

tests/**/test_*.py: New feature tests must follow the STD-first workflow: (1) STP (Software Test Plan) reviewed and approved, (2) STD (Software Test Description) placeholder tests with docstrings and __test__ = False reviewed, (3) Implementation only after STD review. Never submit test implementation without prior STD review.
Every new feature test file must include an STP link in the module, class, or test docstring. If there is no STP, the module, class, or test docstring must include a link to the RFE or Jira epic (not support cases) for coverage tracking.
All new tests must have markers. Check pytest.ini for available markers. Tier marker semantics: tier1 = operator/infrastructure tests, tier2 = customer use case tests, tier3 = complex/hardware/platform-specific/time-consuming tests. Assign the correct tier based on what the test validates. tier2 is implicit and added automatically to all tests without exclusion markers—do NOT add it explicitly. Team markers (network, storage, virt, iuo, observability, infrastructure, data_protection, chaos) are implicit based on directory location—do NOT add them explicitly.
Each test must verify ONE aspect only with a single purpose. Tests must be independent. Use pytest-dependency only when test B requires side effects from test A (e.g., cluster-wide configuration). For resource dependencies, use shared fixtures instead. When using @pytest.mark.dependency, include a comment explaining WHY the dependency exists.
Always use @pytest.mark.usefixtures when fixture return value is not used by test. This is REQUIRED.
__test__ = False is ALLOWED only for STD placeholder tests that contain only docstrings describing expected behavior with no implementation code (no assertions, no test logic). Once a test has implementation code (assertions, test logic, setup/teardown), __test__ = False must be removed.

This enables future extensibility for configuring secondary interfaces' IP addresses without changing call sites. Apply this pattern to all Python test files under tests.

Learning: In the openshift-virtualization-tests repository, when using VirtualMachine objects from ocp-resources in tests, if vm.ready is True, vm.vmi is guaranteed to exist. Therefore, you can access vm.vmi.instance.status or vm.vmi attributes without additional defensive checks (e.g., if vm.vmi: ...). Do not rely on vm.vmi being present when vm.ready may be False; guard those code paths accordingly. This guideline applies to tests under tests/ (notably in virt/upgrade/conftest.py and related test modules) and should be followed for any code paths that assume vm.vmi exists only when vm.ready is True.

Learning: In integration/functional tests located under the tests/ directory, require assertion failure messages using the pattern: assert condition, "descriptive message". For unit tests under utilities/unittests/, rely on pytest's assertion introspection and descriptive test names; explicit failure messages are not required. This guidance helps maintain clear diagnostics for integration tests while keeping unit tests concise and leveraging pytest's built-in introspection.

Apply this guidance to all Python tests under tests/, including tests/network/localnet/test_non_udn_localnet.py, ensuring tier3 designation is reserved for genuine platform-specific or complex scenarios rather than general networking infra necessities.

Learning: In this repo’s OpenShift virtualization tests, it is a standard pattern to call `to_dict()` on `ocp-resources` objects (e.g., `DataVolume`) without using its return value. The call is used only to populate the object’s `res` attribute, which is then read or mutated (e.g., `dv.res[...] = ...`). Do not flag this as an unused return value and do not request adding an inline comment just to justify it, since maintainers treat this behavior as consistent and intentional across the codebase.

Learning: In this repository’s pytest suite, some STD (Standard Definition) placeholder tests under the `tests/` directory are intentionally implemented as docstring-only functions. They must be marked with `__test__ = False` immediately after the function definition (e.g., `test_x.__test__ = False`) to prevent pytest from collecting/executing them until the real test body exists. During code review, do not flag these as missing executable coverage and do not recommend removing or changing the `__test__ = False` setting when the placeholder pattern matches this accepted STD approach.

Those fixtures guarantee the datasource exists and provides a valid size, and other repo usages follow the same pattern without additional fail-fast/`None` checks; therefore, reviewers should not flag missing `None` guarding in this specific fixture-driven scenario.

Specifically: (1) For Category 1 (Product Bug), require `pytest.mark.jira("CNV-XXXXX", run=False)` and do not suggest replacing it with `xfail` (the `pytest_jira` plugin conditionally skips when the Jira issue is open). (2) For Category 2 (Automation Issue), require `pytest.mark.xfail(run=False, reason=...)` (pytest handles the skip). During review, flag quarantine PRs that use the wrong marker/category, omit a Jira ticket reference for Category 1, or use `run=False` in an incorrect context; raise these compliance questions even if later resolution confirms the marker was correct.

Learning: In this codebase, when using `retry` imported from `timeout_sampler`, the decorated function must indicate success by returning a truthy value. The decorator retries until it encounters a truthy `sample` (i.e., it does `if sample: return sample`). Therefore, ensure `retry`-decorated functions include `return True` (or another truthy value) on success; avoid removing/altering it on the assumption that the caller ignores the return value. If the function returns `None` (or has no return statement), it will keep retrying and typically end in `TimeoutExpiredError`.

These `# noqa: PID001` comments are intentional and effective, commonly used on base-class `test_*` methods where the Polarion markers are defined on subclass overrides.

Learning: When reviewing Python code in this repository, do NOT flag short loop variables like `i` (or other short names) as non-descriptive when they are used as the index in a simple `enumerate()` loop where the variable’s role is immediately obvious from context and the loop body is a single straightforward statement (e.g., `for i, addresses in enumerate(ip_addresses): ethernets[f"eth{i + 1}"] = ...`). In these cases, keep the short index variable and do not recommend renaming it to a longer form like `interface_index`.

When reviewing lints such as `ARG002` (unused argument), do not flag that `param_name` as unused if it only exists to trigger indirect fixtures or to drive other fixtures via the fixture dependency chain— even if the test body never references the value directly.

Learning: In this repo’s test suite, the `hco_namespace` pytest fixture (defined in `tests/conftest.py`) returns an OpenShift `Namespace` Resource object created by `utilities.hco.get_hco_namespace(...)`. When a function receives `hco_namespace` as a fixture argument, it is valid to access `hco_namespace.name` and it will be the namespace name string. Code review should not flag `hco_namespace.name` as a potential `AttributeError` when the value originates from the `hco_namespace` fixture (i.e., passed in via the fixture parameter); only warn if the value was assigned/derived from something other than the fixture.

Learning: When reviewing Python code in this repository for Ruff/linter rule rollouts, do not treat temporary suppression comments as violations in the specific migration scenario where a PR enables a new Ruff rule (e.g., PLC0415) and the PR description explicitly documents that all *pre-existing* violations are being annotated with `# noqa: <RULE>` as a short-lived measure. In that case, only flag `# noqa: <RULE>` suppressions that are newly introduced on code that did not previously violate the rule—i.e., verify via the PR diff against the prior state (and/or prior Ruff findings) that the suppressed line was already violating before the rule was enabled. Ignore suppressions that are covering violations that existed before the new rule rollout and were intentionally bulk-added for cleanup in follow-up PRs.

Learning: When reviewing Python code in RedHatQE/openshift-virtualization-tests, avoid flagging Ruff `# noqa: <RULE>` suppressions as issues if they were intentionally added as a temporary measure to keep CI green after a PR enables a new Ruff/lint rule (e.g., PLC0415) and the PR description documents this under "Special notes for reviewer". Treat these suppressions as deferred technical debt. Only flag `# noqa: PLC0415` (and similar rule-specific suppressions) when they are newly introduced without an accompanying documented intent in the PR (and thus appear to be masking a new violation rather than a pre-existing one).

Learning: In this repository (RedHatQE/openshift-virtualization-tests), do not flag missing return type annotations or missing argument type annotations as Ruff “ANN” rule violations (e.g., ANN001/ANN002/ANN201/ANN202). The repo’s Ruff configuration does not enable ANN rules and only uses `extend-select = ["PLC0415"]`, so missing type annotations should not be treated as ANN lint failures during code review.

Learning: When using Kubernetes API models like `NodeSelectorRequirement` or `LabelSelectorRequirement` with operators `Exists` or `DoesNotExist`, the `values` field must not be non-empty. It is valid for `values` to be omitted / left as `None` (Python) / passed as `null`—Kubernetes rejects non-empty `values` for these operators, but does not require the field to be present or explicitly set to an empty list. In code reviews, do not treat missing `values=[]` for `Exists`/`DoesNotExist` as a validation issue; only flag cases where `values` is provided with actual elements.

Learning: When constructing Kubernetes `NodeSelectorRequirement` (or `LabelSelectorRequirement`) objects in code, do not treat `values` being omitted, `None`, or an empty list as an API-validation problem when the requirement’s operator is `Exists` or `DoesNotExist`. Per the Kubernetes API spec, these operators only require that the `values` array is not non-empty (i.e., it must be empty); they do not require the field to be explicitly present as `[]`. Therefore, reviewers should not flag `values=None`/missing `values` for `Exists`/`DoesNotExist`.

Learning: For Python files in this repo, don’t raise review findings for missing type hints or missing/Google-style docstrings on an existing function when the PR’s only functional change is adding one or more new parameters to that function and the PR does not otherwise refactor or substantially rewrite its body/signature. Treat type-annotation/docstring improvements as out of scope for focused parameter-add PRs and defer them to a follow-up. Only raise missing type-hint or docstring issues when the PR introduces an entirely new function or substantially rewrites an existing one.

Learning: In tests/observability/metrics/test_vms_metrics.py, for the vm_in_starting_state fixture, prefer using a fixed time.sleep(30) after vm.start() to capture the kubevirt_vm_starting_status_last_transition_timestamp_seconds metric during a transient window, instead of polling with TimeoutSampler. This is preferred because: 1) different storage classes behave differently and the exact status is not relevant, 2) the metric should be captured within a time window regardless of status, and 3) 30 seconds is sufficient and more efficient than waiting up to 3 minutes for a specific status.

Learning: During review of PRs that are lint cleanups or tooling/version bumps, do not flag code-quality issues for patterns that pre-existed before the PR. Specifically, if the diff does not introduce/modify constructs such as nested `if` blocks or unnecessary list comprehensions, treat them as known/deferred and leave them for dedicated follow-up cleanup PRs. Only raise issues when the PR itself adds, changes, or refactors the problematic code.

Learning: In this repo’s test suite (under `tests/`), module-level triple-quoted string blocks used as STD documentation for shared preconditions (e.g., a `"""Preconditions: ..."""` block placed after `pytestmark`) are intentional. Do not flag them as dead code and do not suggest moving them into module/class docstrings or deleting them, as they are a consistent documentation convention across STD test modules.

📝 Walkthrough

Walkthrough

Tests now pass a cdi_config fixture into PVC size calculation. get_pvc_size_bytes accepts an optional cdi_config and, when present and PVC volumeMode is "Filesystem", reduces the requested size by CDI filesystem overhead (per-storage-class, with global fallback).

Changes

PVC size utils & tests

Layer / File(s)	Summary
Filesystem-overhead-aware PVC size helper tests/observability/metrics/utils.py	Adds CDIConfig import and changes `get_pvc_size_bytes(vm, cdi_config: CDIConfig
Update metrics tests to pass cdi_config tests/observability/metrics/test_vms_metrics.py	Two disk-allocated-size tests (Linux and Windows) now accept a cdi_config fixture and pass it into get_pvc_size_bytes when computing expected_value.

PersistentVolumeClaim size parsing: in the assignment to raw_size_bytes that
uses bitmath.parse_string_unsafe(...).Byte.bytes, drop the intermediate .Byte
and use .bytes directly (i.e., call bitmath.parse_string_unsafe(...).bytes) so
raw_size_bytes becomes an int of the numeric byte value; keep the rest of the
logic (pvc, cdi_config check, and return) unchanged.
