cloudpathlib.local¶
This module implements "Local" classes that mimic their associated cloudpathlib
non-local
counterparts but use the local filesystem in place of cloud storage. They can be used as drop-in
replacements, with the intent that you can use them as mock or monkepatch substitutes in your
tests. See "Testing code that uses cloudpathlib" for usage
examples.
