Fix Windows path compatibility using tmp_path fixture

The previous fix still failed on Windows because Path() objects created
from Unix-style paths (/tmp/file) are not equal to Path objects created
from Windows-style paths (D:\tmp\file), even when comparing Path objects.

Solution: Use pytest's tmp_path fixture to create platform-appropriate
absolute paths for testing. This ensures the test works correctly on all
platforms (Windows, Linux, macOS) by using real absolute paths from the
filesystem.

The test now verifies:
1. The path returned equals the path provided (using actual absolute paths)
2. The path is absolute (using path.is_absolute())

This approach is more robust and platform-agnostic.
