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.
