| Expected result | success when no violation is found; error when the rule is violated. |
| Fuzzing logic | Inspects the OpenAPI contract without sending HTTP requests and reports violations of this rule. |

| HTTP methods that will be skipped | N/A — no HTTP requests are sent. |
| Reporting | Reports error if no versioning information is found, or success otherwise. |
