What comments do you want to add?
// TestGetDaemonset is a unit test for the AlluxioEngine.getDaemonset method.
// It uses a fake Kubernetes client to simulate an AlluxioRuntime and a corresponding DaemonSet object,
// verifying whether getDaemonset correctly retrieves the expected DaemonSet based on the provided name and namespace.
// The test checks both the returned object and error status to ensure functional correctness and robustness.
