Add comments to TestSyncMetadataWithoutMaster in pkg/ddc/alluxio/metadata_test.go

[BitingStorm]

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)
