might be a good idea to declare 1024 as a constant as it is used more than once

I think this's not needed as I only used twice and the 1024 indicates the number of bytes

Why aren't there test cases for the zmount and qsfs workload type?

why do you only have tests for workload type zmachine when there are other types we can test as well? I think we should write more tests that test workload types other than zmachine for a more extensive test coverage.
