+// TestGetHCFSStatus tests various scenarios of the GetHCFSStatus method.
+// This test verifies the logic of retrieving HCFS status, covering the following cases:
+// 1. In the normal case, it should correctly return the expected endpoint and filesystem version.
+// 2. When the service is not registered, GetHCFSStatus should return an appropriate error.
+// 3. When an error occurs during configuration retrieval, GetHCFSStatus should return the error.
+// The test uses mocks of kubeclient.ExecCommandInContainerWithFullOutput to simulate different outputs.
