mdr-operator: add MDRT negative validation test (RHWA-1249) - #88
Conversation
Validates that the API server rejects MachineDeletionRemediationTemplate CRs with invalid metadata: non-existent namespace (-2) returns NotFound, invalid name (-1-invalid-value) returns RFC 1123 validation error. Ported from ocp-edge-auto test_mdr_cli.py TestMDRNegativeScenarios. RHWA-1249 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The change adds negative validation coverage, but one assertion should use the structured Kubernetes invalid-error reason rather than matching rendered text to remain stable across message-format changes.

structured Kubernetes reason via k8serrors.IsInvalid(err) instead of matching
rendered error text; if validation must be limited to the resource name,
additionally inspect the StatusCause.Field value for metadata.name.

For k8s.io/apimachinery v0.35.2, does pkg/api/errors.IsInvalid classify Kubernetes API responses with reason Invalid?
💡 Result:
Yes, for k8s.io/apimachinery v0.35.2, the function pkg/api/errors.IsInvalid classifies Kubernetes API responses with the reason Invalid [1][2]. The IsInvalid function determines if an error indicates a resource is invalid by checking two conditions [1]: 1. It checks if the error's reason is equal to metav1.StatusReasonInvalid (which corresponds to the string "Invalid") [1]. 2. It also returns true if the error's HTTP status code is http.StatusUnprocessableEntity (422) and the reason is not a known reason, ensuring broader compatibility with API responses that may not explicitly include the "Invalid" reason string [1][2]. This dual-check approach allows the function to identify "Invalid" errors even in scenarios where the explicit reason field might be missing or different, provided the HTTP status code correctly identifies the response as an unprocessable entity [1][2].

k8s.io/apimachinery v0.35.2 pkg/api/errors IsInvalid StatusError Details Causes source
💡 Result:
In the k8s.io/apimachinery library (version v0.35.2), the StatusError type, its validation methods, and the associated error details are located in the pkg/api/errors package [1][2]. StatusError Structure The StatusError type is defined as a struct that wraps a metav1.Status object [3][4]: type StatusError struct { ErrStatus metav1.Status } APIStatus Interface The package provides an APIStatus interface, which is implemented by StatusError to allow access to the underlying metav1.Status [3][4]: type APIStatus interface { Status metav1.Status } Validation and Details The IsInvalid function determines if an error indicates that a resource is invalid by checking if the StatusReason matches metav1.StatusReasonInvalid [1][5]. The Details field within the Status object is of type *metav1.StatusDetails, which contains a Causes field [1][6]. The Causes field is a slice of metav1.StatusCause objects, each containing: - Type: The type of the cause (e.g., CauseTypeFieldValueInvalid, CauseTypeFieldValueRequired) [7]. - Message: A human-readable description of the error [1]. - Field: The specific field path that caused the error [1][7]. Creation The NewInvalid function is commonly used to create these errors. It accepts a qualified kind, a name, and a list of field errors (field.ErrorList), transforming them into the StatusDetails structure with the appropriate Causes [1][5]: func NewInvalid(qualifiedKind schema.GroupKind, name string, errs field.ErrorList) *StatusError Source Code The source code for this package is managed within the main Kubernetes repository under the staging/src/k8s.io/apimachinery directory and is synced to the standalone k8s.io/apimachinery repository [8][2]. You can inspect the implementation in the pkg/api/errors/errors.go file within that repository [1].

Use the structured Kubernetes error reason.
Replace the rendered-message check with k8serrors.IsInvalid(err). If name-specific validation is required, inspect StatusCause.Field for metadata.name.

Tested on AWS OCP 4.22 nightly (cluster-bot, 3 masters + 3 workers): OCP-60889: MDRT with invalid namespace (-2) rejected with NotFound, MDRT with invalid name (-1-invalid-value) rejected with RFC 1123 error. Controller pod verified running after test. |

- Fix DeferCleanup for invalid-namespace case to delete via the original object reference (correct namespace), not cleanupMDRT - Change test namespace from "-2" (syntactically invalid) to "mdr-test-nonexistent-ns" (valid but non-existent) to guarantee NotFound response across K8s versions - Replace string matching for RFC 1123 error with k8serrors.IsInvalid() - Remove ComponentController label (test validates K8s API server admission, not MDR controller behavior) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Thanks for addressing my comments, looks much better 👍🏻
- Add By() and error logging to DeferCleanup for invalid-namespace MDRT (can't use cleanupMDRT here -- it hardcodes OperatorNs, but this MDRT was created in a different namespace) - Remove AfterAll pod-running assertion from README pass criteria (AfterAll failures don't attach to OCP-60889's Polarion JUnit result) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

@razo7 , can you please re-approve ? |
Fix the two APIClient.Create calls (lines 70, 93) that still used context.TODO(); the rest of the MDR suite uses context.Background(). Addresses razo7 follow-up on PR medik8s#88. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
