# Command Tests :: `.model`

### Scope

- **Purpose**: Integration test cases for the `.model` get/set command.
- **Source**: `docs/cli/command/007_model.md`, `docs/feature/035_model_command.md`
- **Covers**: AC-01 through AC-13

### Test Cases

| IT | AC | Scenario | Source fn |
|----|----|-----------|-|
| IT-01 | AC-01 | Get: settings.json has `{"model":"opus"}` → prints `model: opus` | `ft01_get_model_opus` |
| IT-02 | AC-02 | Get: settings.json has `{"model":"sonnet"}` → prints `model: sonnet` | `ft02_get_model_sonnet` |
| IT-03 | AC-03 | Get: model key absent → prints `model: (unset)` | `ft03_get_model_unset_key_absent` |
| IT-04 | AC-04 | Get: settings.json does not exist → prints `model: (unset)` | `ft04_get_model_unset_file_absent` |
| IT-05 | AC-05 | `set::opus` → writes `claude-opus-4-6` to settings.json | `ft05_set_opus_writes_full_id` |
| IT-06 | AC-06 | `set::sonnet` → writes `claude-sonnet-4-6` | `ft06_set_sonnet_writes_full_id` |
| IT-07 | AC-07 | `set::haiku` → writes `claude-haiku-4-5-20251001` | `ft07_set_haiku_writes_full_id` |
| IT-08 | AC-08 | `set::default` → removes model key; other keys preserved | `ft08_set_default_removes_key_preserves_others` |
| IT-09 | AC-09 | `set::bad` → exit 1, stderr names all 4 valid values | `ft09_set_bad_value_exits_1` |
| IT-10 | AC-10 | Set on absent settings.json → file created with model key | `ft10_set_creates_file_when_absent` |
| IT-11 | AC-11 | Set on settings.json with other keys → all keys preserved | `ft11_set_preserves_existing_keys` |
| IT-12 | AC-12 | Get `format::json` → `{"model":"opus"}` or `{"model":null}` | `ft12_get_json_format` |
| IT-13 | AC-13 | `.model` appears in `clp .help` output | `it13_model_listed_in_help_output` |

### Notes

- All IT cases are integration tests in `tests/cli/model_test.rs`.
- IT-03 and IT-04 require an isolated `~/.claude/` home fixture without a model key.
- IT-08 and IT-11 require seeded `settings.json` with pre-existing keys.
- IT-09 does not require a credential store — parameter validation fires first.
