# XR Interaction Test

Test 12 suites covering XR interaction behaviors: entity discovery, ECS registration, ray interaction, poke/touch, dual-mode, cross-entity isolation, input mode switching, rapid poke cycles, audio, UI panel, and stability.

**Configuration:**

- EXAMPLE_DIR: `$IWSDK_REPO_ROOT/examples/poke`

**Tool calls**: every tool call is `npx iwsdk <subcommand> [--input-json '<JSON>'] [--timeout <ms>]`, run from inside the example workspace (cwd `$EXAMPLE_DIR`). The CLI auto-discovers the IWSDK app root from cwd, so no path tricks are required. Run `npx iwsdk mcp inspect` from the example to discover available tools and their CLI subcommands.

- `<JSON>` is a JSON object string. Omit `--input-json` if no arguments are needed.
- Output is JSON on stdout: `{ok, workspaceRoot, operation, result}`. Parse it to check assertions.
- Use `--timeout 20000` for operations that may take longer (reload, xr enter, xr animate-to, screenshot).

**IMPORTANT**: Run each Bash command one at a time. Parse the JSON output and verify assertions before moving to the next command. Do NOT chain multiple CLI commands together.

**IMPORTANT**: When the instructions say "wait N seconds", use `sleep N` as a separate Bash command.

---

## Step 1: Install Dependencies

```bash
cd $IWSDK_REPO_ROOT/examples/poke && npm run fresh:install
```

Wait for this to complete before proceeding.

---

## Step 2: Start Dev Server

Start the dev server as a background task using the Bash tool's `run_in_background: true` parameter:

```bash
cd $IWSDK_REPO_ROOT/examples/poke && npm run dev
```

**IMPORTANT**: This command MUST be run with `run_in_background: true` on the Bash tool — do NOT append `&` to the command itself.

Once the background task is launched, poll the output for Vite's ready message (up to 60s). You can also run `npx iwsdk dev status` from the example directory until `state.running` becomes `true`. You do not need to extract or manage the port yourself; subsequent commands resolve the active runtime through the CLI automatically.

If the server fails to start within 60 seconds, report FAIL for all suites and skip to Step 5.

---

## Step 3: Verify Connectivity

```bash
npx iwsdk ecs systems 2>/dev/null
```

This must return JSON with a list of systems. If it fails:

1. Check `/tmp/iwsdk-dev-interactions.log` for errors
2. Try killing and restarting the server (Step 2)
3. If it still fails, report FAIL for all suites and skip to Step 5

---

## Step 4: Run Test Suites

### Pre-test Setup

Run these commands in order:

1. `npx iwsdk browser reload --timeout 20000 2>/dev/null`
   Then: `sleep 3`

2. `npx iwsdk xr enter --timeout 20000 2>/dev/null`
   Then: `sleep 2`

3. `npx iwsdk browser logs --input-json '{"count":20,"level":["error"]}' 2>/dev/null`
   Assert: No error-level logs. Warnings about audio autoplay are acceptable.

---

### Suite 1: Entity Discovery

Discover all testable entities dynamically. These entity indices are used by all subsequent suites.

**Test 1.1: Find Robot Entity**

```bash
npx iwsdk ecs find --input-json '{"withComponents":["Robot"]}' 2>/dev/null
```

Assert: Exactly 1 entity. Save its `entityIndex` as `<robot>`.

**Test 1.2: Find Panel Entity**

```bash
npx iwsdk ecs find --input-json '{"withComponents":["PanelUI"]}' 2>/dev/null
```

Assert: Exactly 1 entity. Save its `entityIndex` as `<panel>`.

**Test 1.3: Get Robot World Position**

```bash
npx iwsdk scene hierarchy --input-json '{"maxDepth":3}' 2>/dev/null
```

Find the robot's Object3D UUID (match `entityIndex` = `<robot>`).
Then:

```bash
npx iwsdk scene transform --input-json '{"uuid":"<robot-uuid>"}' 2>/dev/null
```

Save `positionRelativeToXROrigin` as `<robot-pos>`. Expected near `(0, 0.95, -1.5)`.

**Test 1.4: Get Panel World Position**
Same approach — find panel's UUID from hierarchy, query transform.

```bash
npx iwsdk scene transform --input-json '{"uuid":"<panel-uuid>"}' 2>/dev/null
```

Save `positionRelativeToXROrigin` as `<panel-pos>`. Expected near `(0, 1.5, -1.4)`.

---

### Suite 2: ECS Registration

**Test 2.1: List Systems**

```bash
npx iwsdk ecs systems 2>/dev/null
```

Assert these systems are present: `RobotSystem`, `PanelSystem`, `InputSystem`, `AudioSystem`, `PanelUISystem`.

**Test 2.2: List Components**

```bash
npx iwsdk ecs components 2>/dev/null
```

Assert these components are registered:

- `Robot`
- `PanelUI` (with fields: `config`, `maxWidth`, `maxHeight`)
- `AudioSource` (with fields: `src`, `loop`, `_loaded`, `_isPlaying`, `_playRequested`)
- `RayInteractable`
- `PokeInteractable`
- `ScreenSpace`

- `downRadius: 0.02m` (2cm) — triggers auto-select (pointerdown)

**Test 4.1: Position Near Robot**

```bash
npx iwsdk xr set-transform --input-json '{"device":"controller-right","position":{"x":<robot-pos.x>,"y":<robot-pos.y>,"z":<z+0.3>},"orientation":{"pitch":0,"yaw":180,"roll":0}}' 2>/dev/null

npx iwsdk xr animate-to --input-json '{"device":"controller-right","position":{"x":<robot-pos.x>,"y":<robot-pos.y>,"z":<z-0.3>},"duration":2.5}' --timeout 20000 2>/dev/null
```

(where `<z-0.3>` = `<robot-pos.z> - 0.3`)
Then: `sleep 1.5`

```bash
npx iwsdk ecs query --input-json '{"entityIndex":<robot>,"components":["Hovered","Pressed"]}' 2>/dev/null
```

Assert: At least `Hovered` present. `Pressed` may also be present.

npx iwsdk xr animate-to --input-json '{"device":"controller-right","position":{"x":0.3,"y":1.5,"z":-0.3},"duration":0.3}' --timeout 20000 2>/dev/null
```

Then: `sleep 0.5`

```bash
npx iwsdk ecs query --input-json '{"entityIndex":<robot>,"components":["Hovered","Pressed"]}' 2>/dev/null
```

Assert: Neither `Hovered` nor `Pressed` present.

### Suite 9: Rapid Poke Cycles (Regression)

Test that multiple poke-release cycles all clean up properly (no stuck Pressed).

For each of 3 cycles:

1. Position at `{x: <robot-pos.x>, y: <robot-pos.y>, z: <robot-pos.z> + 0.4}` with yaw 180:
   ```bash
   npx iwsdk xr set-transform --input-json '{"device":"controller-right","position":{"x":<robot-pos.x>,"y":<robot-pos.y>,"z":<rz+0.4>},"orientation":{"pitch":0,"yaw":180,"roll":0}}' 2>/dev/null
   ```
2. Animate through:
   ```bash
   npx iwsdk xr animate-to --input-json '{"device":"controller-right","position":{"x":<robot-pos.x>,"y":<robot-pos.y>,"z":<rz-0.3>},"duration":1.5}' --timeout 20000 2>/dev/null
   ```
3. `sleep 1.5`, then query `<robot>` for `["Hovered","Pressed"]`. Assert: at least `Hovered` or `Pressed` present.
4. Animate back:
   ```bash
   npx iwsdk xr animate-to --input-json '{"device":"controller-right","position":{"x":<robot-pos.x>,"y":<robot-pos.y>,"z":<rz+0.5>},"duration":0.3}' --timeout 20000 2>/dev/null
   ```
5. `sleep 0.5`, then query `<robot>` for `["Hovered","Pressed"]`. Assert: neither present.

All 3 cycles must pass.

### Suite 10: Audio

**Test 10.1: Find Audio Entities**

```bash
npx iwsdk ecs find --input-json '{"withComponents":["AudioSource"]}' 2>/dev/null
```

Assert: At least 1 entity found. Use the first as `<audio>`.

**Test 10.2: Verify Audio Loaded**

```bash
npx iwsdk ecs query --input-json '{"entityIndex":<audio>,"components":["AudioSource"]}' 2>/dev/null
```

Assert: `_loaded` = `true`, `src` contains `chime.mp3`.

**Test 10.3: Trigger Playback**

```bash
npx iwsdk ecs set-component --input-json '{"entityIndex":<audio>,"componentId":"AudioSource","field":"loop","value":true}' 2>/dev/null
```

```bash
npx iwsdk ecs set-component --input-json '{"entityIndex":<audio>,"componentId":"AudioSource","field":"_playRequested","value":true}' 2>/dev/null
```

Note: `_playRequested` is consumed within one frame.

**Test 10.4: Verify Playback State**

```bash
npx iwsdk ecs query --input-json '{"entityIndex":<audio>,"components":["AudioSource"]}' 2>/dev/null
```

Assert: `_isPlaying` = `true` (loop is on).

**Test 10.5: Stop Playback**

---

### Suite 11: UI Panel Verification

**Test 11.1: Panel Loading**

```bash
npx iwsdk ecs query --input-json '{"entityIndex":<panel>,"components":["PanelUI","PanelDocument","ScreenSpace"]}' 2>/dev/null
```

Assert:

- `PanelUI.config` contains `welcome.json`
- `PanelUI.maxWidth` approximately `0.5`, `PanelUI.maxHeight` approximately `0.4`
- `PanelDocument` component IS present (proves async panel loading succeeded)
- `ScreenSpace` component IS present

**Test 11.2: Visual Confirmation**

```bash
npx iwsdk browser screenshot --timeout 20000 2>/dev/null
```

Assert: returns a `screenshotPath` (PNG file saved to /tmp).

---

### Suite 12: Stability Check

```bash
npx iwsdk browser logs --input-json '{"count":50,"level":["error","warn"]}' 2>/dev/null
```

Assert: No error-level logs. Warnings about `AudioContext` autoplay policy are acceptable. Pre-existing 404 resource errors from page load are acceptable.

---

## Step 5: Cleanup & Results

Kill the dev server:

```bash
cd $IWSDK_REPO_ROOT/examples/poke && npx iwsdk dev down
```

Output a summary table:

```
| Suite                         | Result    |
|-------------------------------|-----------|
| 1. Entity Discovery           | PASS/FAIL |
| 2. ECS Registration           | PASS/FAIL |
| 3. Ray Interaction (Robot)    | PASS/FAIL |
| 4. Poke Interaction (Robot)   | PASS/FAIL |
| 5. Ray Interaction (Panel)    | PASS/FAIL |
| 6. Dual-Mode (Panel)          | PASS/FAIL |
| 7. Cross-Entity Isolation     | PASS/FAIL |
| 8. Input Mode Switching       | PASS/FAIL |
| 9. Rapid Poke Cycles          | PASS/FAIL |
| 10. Audio                     | PASS/FAIL |
| 11. UI Panel                  | PASS/FAIL |
| 12. Stability                 | PASS/FAIL |
```

If any suite fails, include which assertion failed and actual vs expected values.

---

## Recovery

If at any point a transient error occurs (server crash, WebSocket timeout, connection refused, etc.) that is NOT caused by a source code bug:

1. Stop the dev server: `cd $IWSDK_REPO_ROOT/examples/poke && npx iwsdk dev down`
2. Restart: re-run Step 2 to start a fresh dev server
3. Re-run the Pre-test Setup (reload, accept session)
4. Retry the failed suite

Only give up after one retry attempt per suite. If the same suite fails twice, mark it FAIL and continue to the next suite.

---

## Known Issues & Workarounds

### Poke timing sensitivity

The slow animation in poke suites (2-2.5 seconds) is critical. The poke system uses a 2cm `downRadius` threshold — if the controller moves too fast, it can skip past the threshold between frames.

### Audio autoplay

Browsers block audio autoplay until user gesture. The `_playRequested` flag may silently fail. If `_isPlaying` is false, this is a browser policy issue, not a bug.

### One-shot flags consumed immediately

`_playRequested` and `_stopRequested` are processed and reset to `false` within a single frame.

### Entity indices change on reload

Never cache entity indices across page reloads. Always re-discover via `npx iwsdk ecs find`.

### Touch pointer not enabled

`toggleSubPointer('touch', true)` must be called when entities are created, not just at init time.

### Pressed stuck after poke pull-back

Fixed: `processTouchLifecycle` now dispatches `pointer.up()` when intersection is lost in SELECT state.
