                void statusChanged(ProgressEvent event) {
                    if (event instanceof TestMetadataEvent) {
                        if (event instanceof TestFileAttachmentMetadataEvent) {
                            // Do something with file attachment
                        } else if (event instanceof TestKeyValueMetadataEvent) {
                            // Do something with key-values
                        } else {
                            // ignore unrecognized events
                        }
                    }
                }
