Business Context
A data governance team is stress-testing the CAS environment to ensure system integrity and security. They must verify that the `addCaslibSubdir` action fails gracefully and provides clear error messages when used with invalid parameters or in unauthorized ways.
Data Preparation
Setup of a base caslib for testing. A subdirectory 'existing_folder' is also created to test behavior when attempting to create a directory that already exists.

| 1 | PROC CAS; |
| 2 | caslib govTest path='/cas/data/gov' dataSource={srcType='path'}; |
| 3 | TABLE.addCaslibSubdir / caslib='govTest' path='existing_folder'; |
| 4 | RUN; |
Étapes de réalisation
1
Attempt to create a subdirectory in a caslib that does not exist. This should result in an error.
Copied!
| 1 | |
| 2 | PROC CAS; |
| 3 | TABLE.addCaslibSubdir / caslib='nonExistentCaslib' path='should_fail'; |
| 4 | RUN; |
| 5 |
2
Attempt to create a subdirectory using an invalid permission string. The action should reject the unknown value.
Copied!
| 1 | |
| 2 | PROC CAS; |
| 3 | TABLE.addCaslibSubdir / caslib='govTest' path='invalid_perms' permission='ALLOW_ALL'; |
| 4 | RUN; |
| 5 |
3
Attempt to create a subdirectory that already exists. The system should return a specific error or warning indicating the conflict.

| 2 | PROC CAS; |
| 3 | TABLE.addCaslibSubdir / caslib='govTest' path='existing_folder'; |
| 4 | RUN; |

4
Attempt to create a directory using a path that tries to escape the caslib's root (directory traversal). This should be blocked for security.
Copied!
| 1 | |
| 2 | PROC CAS; |
| 3 | TABLE.addCaslibSubdir / caslib='govTest' path='../attempted_escape'; |
| 4 | RUN; |
| 5 |
Expected Result
Each test step is expected to fail. The SAS log for each step should contain a clear ERROR or WARNING message explaining the reason for failure: caslib not found, invalid permission value, directory already exists, or invalid path. The file system should remain unchanged by these failed attempts, demonstrating the action's robustness and security.
