Environment System Test

Run 6 test suites covering default lighting verification, system registration, component registration, scene hierarchy, ECS data modification, 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, 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.

IMPORTANT: Boolean values in ecs set-component must be actual JSON booleans (value: true), NOT strings (value: "true"). Strings silently fail to coerce.

Step 1: Install Dependencies

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:

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

npx iwsdk ecs systems 2>/dev/null

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

1. Check the dev server output 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","warn"]}' 2>/dev/null Assert: No error-level logs.

Suite 1: Default Lighting Verification

Test 1.1: Find LevelRoot Dynamically

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

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

Test 1.2: LevelRoot Has Environment Components

npx iwsdk ecs query --input-json '{"entityIndex":<root>,"components":["DomeGradient","IBLGradient"]}' 2>/dev/null

Assert: Both components present with default values:

DomeGradient defaults:

IBLGradient defaults:
