PeriodicTimer in BackgroundService does it belong to unit tests?

public sealed class DataSyncBackgroundService : BackgroundService
{
    private readonly IServiceScopeFactory _scopeFactory;
    private readonly ILogger<DataSyncBackgroundService> _logger;

    public DataSyncBackgroundService(
        IServiceScopeFactory scopeFactory,
        ILogger<DataSyncBackgroundService> logger)
    {
        _scopeFactory = scopeFactory;
        _logger = logger;
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        using var timer = new PeriodicTimer(TimeSpan.FromSeconds(30));

        do
        {
            try
            {
                using var scope = _scopeFactory.CreateScope();
                var syncService = scope.ServiceProvider.GetRequiredService<IDataSyncService>();
                await syncService.SyncAsync(stoppingToken);
            }
            catch (Exception ex) when (ex is not OperationCanceledException)
            {
                _logger.LogError(ex, "Data sync failed");
            }
        }
        while (await timer.WaitForNextTickAsync(stoppingToken));
    }
}
