Which function do you want to add comments to?
I added comments to function called "TestSyncMetadataWithoutMaster" in pkg/ddc/alluxio/metadata_test.go.
What comments do you want to add?
My comments(notation actually) are as folllows:
// TestSyncMetadataWithoutMaster tests the SyncMetadata method of AlluxioEngine when no master node is available.
// It verifies that runtime phases (Master/Worker/Fuse) and dataset phase are correctly updated to NotReady/Failed states.
// Paramaters:
// - t (*testing.T): Go testing framework's test handler for reporting failures and logging
// Returns:
// - None (test assertions are made through t.Errorf/t.Fatal on failure)
