 ##### Integration tests
 
-<!--
-Integration tests are contained in https://git.k8s.io/kubernetes/test/integration.
-Integration tests allow control of the configuration parameters used to start the binaries under test.
-This is different from e2e tests which do not allow configuration of parameters.
-Doing this allows testing non-default options and multiple different and potentially conflicting command line options.
-For more details, see https://github.com/kubernetes/community/blob/master/contributors/devel/sig-testing/testing-strategy.md

-This question should be filled when targeting a release.
-For Alpha, describe what tests will be added to ensure proper quality of the enhancement.
-
-For Beta and GA, document that tests have been written,
-have been executed regularly, and have been stable.
-This can be done with:
-- permalinks to the GitHub source code
-- links to the periodic job (typically https://testgrid.k8s.io/sig-release-master-blocking#integration-master), filtered by the test name
-- a search in the Kubernetes bug triage tool (https://storage.googleapis.com/k8s-triage/index.html)
--->
+**Alpha:**
 
 1. With the feature gate enabled, test that Services can be created with both new and previous validation
 1. With the feature gate disabled, test that Services can be created with the previous validation, and fail when using the new validation
 1. Disable the feature gate and ensure that the Service can be edited without a validation error being returned
 
+**Beta:**

+Tests have been written: https://github.com/kubernetes/kubernetes/blob/v1.34.0/test/integration/service/service_test.go#L1219-L1309

+Yes, using the following steps:
+
+1. Installed a 1.34 Kubernetes cluster with the `RelaxedServiceNameValidation` feature gate disabled
+1. Attempted to create a service with a name starting in a digit - it failed as expected
+1. Upgraded to a custom built 1.35 Kubernetes cluster with the `RelaxedServiceNameValidation` feature gate enabled
+1. Attempted to create a service with a name starting in a digit - it succeeded as expected
+1. Downgraded back to 1.34 with the `RelaxedServiceNameValidation` feature gate disabled
+1. Edited that same service, and it succeeded as expected
 
 ###### Is the rollout accompanied by any deprecations and/or removals of features, APIs, fields of API types, flags, etc.?
