* Fix: trim prefix slash in ListObjectVersionsHandler
* Add test for ListObjectVersions prefix handling
Test validates that prefix normalization works correctly with and without
leading slashes, ensuring the fix for /Veeam/Archive/ style prefixes.
* Simplify prefix test to validate normalization logic
The test now validates that the prefix normalization (TrimPrefix) works
correctly and that normalized prefixes match paths as expected. This is
a focused unit test that validates the core fix without requiring complex
mocking of the filer client.
* Enhance prefix test with full matchesPrefixFilter logic
Added test cases for directory traversal including:
- Directory matching with trailing slash
- canDescend logic for recursive directory search
- Full simulation of matchesPrefixFilter behavior
This provides more comprehensive coverage of the prefix normalization
fix and ensures it works correctly for both files and directories.
