Steps followed:

1. Go through the pytest documentation to use it to write tests and check data integrity.
2. Create an automated script that generates directory and zip stores.
3. Ensure that after every write data integrity is being checked.

Here's the link to what I have so far: https:/caviere/script/blob/master/sample.py

Steps to follow:

1. Add the fsspec implementation to the script and note its performance.
2. Add timing calculations to measure how long certain processes take.
3. Use real-world datasets to compare the different implementations and document the findings.
