Test-lib README now declares its public surface (M.run_tests) so the doc-convention lint passes structural validation. Brings parity with maps-test which already has this section. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# lib-core.command-test
|
|
|
|
Test-lib for `lib-core.command` (Tests-as-Libs per ADR-0037).
|
|
|
|
**Version:** 0.1.0
|
|
**Lib-ID:** lib-core.command-test
|
|
**Requires:** lib-core.command v>=0.1.0, lib-core.input v>=0.4.0, lib-core.camera v>=0.3.0
|
|
**Tags:** test, command
|
|
|

## API
|
|
|
|
### `run_tests(ctx)`
|
|
**Syntax:** `M.run_tests(ctx)` -> void
|
|
|
|
**Description:** Test-runner entrypoint. Executes 25 assertions against
|
|
`lib-core.command`. Called automatically by the engine's
|
|
`--test-libs=` orchestrator. Exits via `engine.exit(engine.test.failures())`.
|
|
|
|
## Coverage Statement
|
|
|
|
Per Fault-Injection-Audit-Convention (2026-05-16):
|
|
|
|
| Section | Assertion-Count | Coverage |
|
|
|---|---|---|
|
|
| Register / Unregister | 3 | `register` handle, `count_registered` after register/unregister |
|
|
| Move-Issue + State-Query | 3 | `move_to`, `current` returns move-data, `is_moving` true after issue, false for idle |
|
|
| State-Query (idle) | 2 | `current` returns nil for idle, `is_moving` false for unknown handle |
|
|
| Update-step | 2 | `update` moves 10px in 0.1s @ 100 px/s, y unchanged for horizontal move |
|
|
| Arrival-snap | 2 | Snap to target.x when step >= dist, `current` cleared after arrival |
|
|
| Cancel + cancel_all | 5 | `cancel(h2)` clears h2 only, `cancel_all` clears remaining; cancel_all clears 2-unit batch |
|
|
| Speed-Setter | 2 | `speed` from register, `set_speed` updates |
|
|
| Arrive-Threshold + Enabled | 3 | Default threshold = 2, `set_arrive_threshold` writes, `enabled` toggle |
|
|
| Error-Handling | 2 | `register` with non-function errors, `move_to` with unknown handle errors |
|
|
| **TOTAL** | **24** | |
|
|
|
|
### Tested-Surface
|
|
- `command.register`, `command.unregister`, `command.count_registered`
|
|
- `command.move_to`, `command.current`, `command.is_moving`
|
|
- `command.cancel`, `command.cancel_all`
|
|
- `command.speed`, `command.set_speed`
|
|
- `command.arrive_threshold`, `command.set_arrive_threshold`
|
|
- `command.enabled`, `command.set_enabled`
|
|
- `command.update` (step + arrival-snap)
|
|
|
|
### Fault-Injection Audit (2026-05-16)
|
|
|
|
Verified via deliberate-mutation in fixture-mirror; mutations reverted after observation.
|
|
|
|
#### Caught Mutations
|
|
|
|
| # | Mutation | Caught by |
|
|
|---|---|---|
|
|
| M1 | `M.move_to` prefixed with `do return end` (complete no-op) | 6 assertions fail: `current returns move-command data`, `is_moving true after move_to`, `update moves 10px`, `arrival snap to target.x`, `cancel doesn't affect h3`, `move_to with unknown handle errors` |
|
|
| M2 | `M.is_moving` prefixed with `do return false end` (always false) | `is_moving true after move_to` fails |
|
|
|
|
#### Uncaught Mutations (Gaps) — Cheap-Fill Applied
|
|
|
|
| # | Original Gap | Fill | Re-Inject Verifies |
|
|
|---|---|---|---|
|
|
| M3 | `M.cancel_all` rewritten to break after first entry | Added 2-unit batch scenario; asserts h2 + h3 both nil after `cancel_all` | ✓ |
|
|
|
|
### Structurally Untestable
|
|
- None identified at headless level — entire surface exercisable via mocked-unit closure-state helper.
|
|
|
|
### Deferred
|
|
- Multi-frame integration with `lib-core.player_control` consumer flow (covered indirectly by player_control-test).
|
|
|
|
## Running
|
|
|
|
Via `--test-libs=lib-core.command-test` (Smoke P0-S-batch Stage):
|
|
|
|
```bash
|
|
Sporel.exe --libs-dir=<libs-path> --test-libs=lib-core.command-test
|
|
```
|
|
|
|
Output is TAP version 13 on stdout; exit-code = failure-count (0 = all pass).
