Release: v1.20
Testname: NetworkPolicies API
Description:
- The networking.k8s.io API group MUST exist in the /apis discovery document.
- The networking.k8s.io/v1 API group/version MUST exist in the /apis/networking.k8s.io discovery document.
- The NetworkPolicies resources MUST exist in the /apis/networking.k8s.io/v1 discovery document.
- The NetworkPolicies resource must support create, get, list, watch, update, patch, delete, and deletecollection.
