Business Context
An R&D engineer is attempting to archive an experimental model to a local filesystem for offline analysis. They are unfamiliar with the API and omit the mandatory directory path, allowing us to test the robustness of parameter validation.
Data Preparation
Train a simple dummy model for quick iteration.
Copied!
| 1 | |
| 2 | DATA casuser.dummy; |
| 3 | x=1; |
| 4 | y=1; |
| 5 | OUTPUT; |

| 7 | RUN; |
| 8 | |
| 9 | PROC CAS; |
| 10 | LOADACTIONSET 'regression'; |
| 11 | regression.glm / TABLE='dummy' target='y' inputs={'x'} store={name='dummy_reg', replace=true}; |
| 12 | LOADACTIONSET 'aStore'; |
| 13 | aStore.save / rstore={name='dummy_reg'} TABLE={name='archive_table', replace=true}; |

Étapes de réalisation
1
Attempt to copy to FILESYSTEM without specifying the 'modelDir' parameter.
Copied!
| 1 | |
| 2 | PROC CAS; |
| 3 | modelPublishing.copyModelExternal / modelTable={name='archive_table', caslib='casuser'} modelName='dummy_reg' externalCaslib='fs_repo' externalOptions={extType='FILESYSTEM'}; |
| 4 | /* Missing modelDir */ |
| 5 | RUN; |
| 6 |
2
Attempt to copy without specifying the 'modelName' parameter.
Copied!
| 1 | |
| 2 | PROC CAS; |
| 3 | modelPublishing.copyModelExternal / modelTable={name='archive_table', caslib='casuser'} externalCaslib='fs_repo' externalOptions={extType='FILESYSTEM', modelDir='/tmp/models'}; |
| 4 | /* Missing modelName */ |
| 5 | RUN; |
| 6 |
Expected Result
The action should fail gracefully in both steps. Step 1 must return an error indicating that 'modelDir' is required for FILESYSTEM type. Step 2 must return an error stating that 'modelName' is a required parameter. The system should not crash.
