# validation/pathValidation - **normalizes Windows paths correctly** – tests that Windows-style paths are normalized for comparison. - **normalizes Unix paths correctly** – ensures Unix paths remain consistent when normalized. - **normalizes GitBash paths correctly** – converts `/c/` style paths to a Windows format for validation. - **validates Windows paths with Windows shell** – allowed directories pass and disallowed ones throw errors. - **validates WSL paths with WSL shell** – confirms that `/mnt/<drive>` paths are checked against allowed entries. - **validates GitBash paths with GitBash shell** – ensures GitBash-specific paths are accepted when within allowed paths. - **allows any path when restriction is disabled** – verifies disabling restrictWorkingDirectory bypasses checks. - **handles empty allowed paths** – when no paths are configured validation should fail with a helpful message.
