### Question:
SyncNotifications { public void showFetchingMailNotification(Account account, Folder folder) { String accountName = account.getDescription(); String folderName = folder.getId(); Context context = controller.getContext(); String tickerText = context.getString(R.string.notification_bg_sync_ticker, accountName, folderName); String title = context.getString(R.string.notification_bg_sync_title); String text = accountName + context.getString(R.string.notification_bg_title_separator) + folderName; int notificationId = NotificationIds.getFetchingMailNotificationId(account); PendingIntent showMessageListPendingIntent = actionBuilder.createViewFolderPendingIntent( account, folderName, notificationId); NotificationCompat.Builder builder = controller.createNotificationBuilder() .setSmallIcon(R.drawable.ic_notify_check_mail) .setWhen(System.currentTimeMillis()) .setOngoing(true) .setTicker(tickerText) .setContentTitle(title) .setContentText(text) .setContentIntent(showMessageListPendingIntent) .setVisibility(NotificationCompat.VISIBILITY_PUBLIC) .setCategory(NotificationCompat.CATEGORY_SERVICE); if (NOTIFICATION_LED_WHILE_SYNCING) { controller.configureNotification(builder, null, null, account.getNotificationSetting().getLedColor(), NOTIFICATION_LED_BLINK_FAST, true); } getNotificationManager().notify(notificationId, builder.build()); } SyncNotifications(NotificationController controller, NotificationActionCreator actionBuilder); void showSendingNotification(Account account); void clearSendingNotification(Account account); void showFetchingMailNotification(Account account, Folder folder); void clearFetchingMailNotification(Account account);  }### Answer:
@Test public void testGetFetchingMailNotificationId() throws Exception { Folder folder = createFakeFolder(); int notificationId = NotificationIds.getFetchingMailNotificationId(account); syncNotifications.showFetchingMailNotification(account, folder); verify(notificationManager).notify(eq(notificationId), any(Notification.class)); verify(builder).setSmallIcon(R.drawable.ic_notify_check_mail); verify(builder).setTicker("Checking mail: " + ACCOUNT_NAME + ":" + FOLDER_NAME); verify(builder).setContentTitle("Checking mail"); verify(builder).setContentText(ACCOUNT_NAME + ":" + FOLDER_NAME); verify(builder).setContentIntent(contentIntent); verify(builder).setVisibility(NotificationCompat.VISIBILITY_PUBLIC); }
