# FT — Feature 035: Dedicated Model Get/Set Command

### Scope

- **Purpose**: Test cases for the `.model` get/set command.
- **Source**: `docs/feature/035_model_command.md`
- **Covers**: AC-01 through AC-12

### Test Cases

| FT | AC | Scenario | Source fn |
|----|----|----------|-----------|
| FT-01 | AC-01 | Get: `{"model":"opus"}` in settings.json → prints `model: opus` | ✅ `ft01_get_model_opus` |
| FT-02 | AC-02 | Get: `{"model":"sonnet"}` in settings.json → prints `model: sonnet` | ✅ `ft02_get_model_sonnet` |
| FT-03 | AC-03 | Get: model key absent → prints `model: (unset)` | ✅ `ft03_get_model_unset_key_absent` |
| FT-04 | AC-04 | Get: settings.json absent → prints `model: (unset)` | ✅ `ft04_get_model_unset_file_absent` |
| FT-05 | AC-05 | `set::opus` → writes `claude-opus-4-6` | ✅ `ft05_set_opus_writes_full_id` |
| FT-06 | AC-06 | `set::sonnet` → writes `claude-sonnet-4-6` | ✅ `ft06_set_sonnet_writes_full_id` |
| FT-07 | AC-07 | `set::haiku` → writes `claude-haiku-4-5-20251001` | ✅ `ft07_set_haiku_writes_full_id` |
| FT-08 | AC-08 | `set::default` → removes model key; other keys preserved | ✅ `ft08_set_default_removes_key_preserves_others` |
| FT-09 | AC-09 | `set::bad` → exit 1, stderr names all four valid values | ✅ `ft09_set_bad_value_exits_1` |
| FT-10 | AC-10 | Set on absent settings.json → file created with model key | ✅ `ft10_set_creates_file_when_absent` |
| FT-11 | AC-11 | Set on settings.json with other keys → all keys preserved | ✅ `ft11_set_preserves_existing_keys` |
| FT-12 | AC-12 | Get `format::json` → `{"model":"opus"}` or `{"model":null}` | ✅ `ft12_get_json_format` |

### Notes

- All FT cases are integration tests in `tests/cli/model_test.rs`.
- AC-13 (`.model` listed in `clp .help`) is verified at the command level (IT-13 in `tests/docs/cli/command/17_model.md`) — no dedicated feature-level test.
- AC-14 (no-duplication) is an architectural constraint verified by code review — no dedicated runtime test.
- FT-03 and FT-04 require an isolated `~/.claude/` home fixture without a model key.
- FT-08 and FT-11 require seeded `settings.json` with pre-existing keys (e.g., `{"theme":"dark"}`).
- FT-09 does not require a credential store (parameter validation fires before any store access).

- **When:** `clp .model`
- **Then:** Stdout is `model: (unset)\n`. Exits 0.
- **Exit:** 0
- **Source fn:** ✅ `ft04_get_model_unset_file_absent`
- **Source:** [035_model_command.md AC-04](../../../docs/feature/035_model_command.md)

---

### FT-05: `set::opus` writes `claude-opus-4-6`

- **Given:** Any `settings.json` state (may or may not exist).
- **When:** `clp .model set::opus`
- **Then:** `~/.claude/settings.json` contains `"model": "claude-opus-4-6"`. Exits 0.
