   Actually, on second thought, be _do_ have some infrastructure for testing this, as we had to do something similar in the past for the parquet_dataset constructor. We have the following fixture for a filesystem that logs if a file get accessed:

   @Salonijain27 would you have time to take a look at this today? Otherwise I can also take a look
