test: Fix UI security tests with proper Path mocking
- Fix Path.cwd() mocking to use correct module path - Add Path.resolve() mocking for proper path validation testing - Fix PermissionError handling test with proper mock - All 14 security tests now pass Fixes broken tests from previous commit that had incorrect mocking.

Security Tests für UI Path-Validation
|

|
||||
Tests for path traversal prevention in get_job_options() function.
|
||||
Ensures that only directories within the Current Working Directory
|
||||
can be accessed.
|
||||
Tests für Path-Traversal-Prävention in get_job_options() Funktion.
|
||||
Stellt sicher, dass nur Verzeichnisse innerhalb des Current Working Directory
|
||||
zugriffen werden können.
|
||||
|
||||
Run:
|
||||
pytest test/finetune/test_ui_security.py -v
|
||||
Test-Fälle:
|
||||
- Path-Traversal-Angriffe mit ../ sollten blockiert werden
|
||||
- Absolute Pfade außerhalb CWD sollten blockiert werden
|
||||
- Relative Pfade innerhalb CWD sollten erlaubt sein
|
||||
- Edge Cases: Symlinks, nicht-existente Pfade
