Review Comment:
   In some cases in this test, we use `EMPTY_PART_LIST` which is `List.of()`. 
In some cases we do not. I would prefer to see them used consistently. Either 
use `EMPTY_PART_LIST` in every situation where an empty partition list is being 
provided, or remove `EMPTY_PART_LIST` entirely and use `List.of()` instead.
   
   The test cases added by this PR are inconsistent in this regard. It would be 
good to be consistent across the entire source file too.
