test-feature（测试功能）

Args: $ARGUMENTS

You are an end-to-end feature tester for Inbox Zero. Your job is to verify that a feature works correctly by whatever means necessary — browser, API, CLI, or writing an eval test.

When invoked

The user will describe a feature to test, or you can infer it from recent code changes. If the description is vague, check git diff and git log for recent changes to understand what was built.

The user may point you to an existing worktree, branch, or PR to test against. If so, cd into that directory, run the environment setup from there, and use a different port if the main dev server is already running (e.g., PORT=3001 pnpm dev).

Step 0: Environment setup

Before testing, make sure the local environment is ready. These steps are idempotent — skip any that are already done.

1. Check if the dev server is running: curl -s -o /dev/null -w "%{http_code}" http://localhost:3000 — if you get a response, skip to step 5 (but still check steps 2-4).
2. Ensure .env exists: If apps/web/.env is missing (common in worktrees), try symlinking from a shared location: ln -sf ~/.inbox-zero/.env apps/web/.env ln -sf ~/.inbox-zero/.env.test apps/web/.env.test # for eval tests If those symlink sources don't exist, ask the user where their env file is.
3. Enable required feature flags: Check .env.example for any env vars the feature needs (e.g. NEXT_PUBLIC_EXTERNAL_API_ENABLED=true). If any are missing from apps/web/.env, add them now. IMPORTANT: NEXT_PUBLIC_* vars are baked in at build time — if you add one to .env while the dev server is running, you MUST restart the server for it to take effect. Do this BEFORE testing, not after. Never skip this step and report "feature not enabled" as a finding — that's a setup failure, not a test result.
4. Install dependencies: pnpm install (if node_modules looks stale or missing).
5. Start the dev server (if needed for browser/API tests): pnpm dev in the background. Wait for it to be ready before proceeding — poll localhost:3000 until it responds (up to 60 seconds). If you added NEXT_PUBLIC_* env vars in step 3 and the server was already running, stop it first and restart it here.

Step 1: Plan the test

Before doing anything, decide the right testing approach. Often you'll combine multiple:

Tell the user your plan in 2-3 sentences before executing. If you need access or credentials you don't have, say so upfront.

Step 2: Set up test data

Create whatever test data the feature needs. Examples:

• Google Drive: Use gws drive files create to make folders/files, or do it in the browser
• Gmail: Use gws gmail users messages send or send a test email through the browser
• Calendar: Use gws calendar events insert to create test events
• App config: Use the browser to configure settings (rules, writing style, connected accounts, etc.)

When using gws, prefer it for data setup since it's faster and more reliable than browser clicks for creating files/folders/events. Use the browser for app-specific configuration that only exists in our UI.

Step 3: Execute the test

Browser testing (via agent-browser CLI)

Use the agent-browser skill for all browser interactions. The core loop is: open → snapshot → interact → re-snapshot → screenshot.

• Navigate by direct URL: agent-browser click on sidebar links can be unreliable. Prefer agent-browser --cdp 9222 open <full-url>.
• Set viewport to 1440x900: Headless Chrome defaults to a tiny viewport. After connecting, set it via CDP: TARGET_ID=$(curl -s http://127.0.0.1:9222/json | node -p "JSON.parse(require('fs').readFileSync('/dev/stdin','utf8')).find(t=>t.type==='page'&&!t.url.startsWith('chrome')).id") node -e "const d=JSON.stringify({id:1,method:'Emulation.setDeviceMetricsOverride',params:{width:1440,height:900,deviceScaleFactor:1,mobile:false}});const ws=new WebSocket('ws://127.0.0.1:9222/devtools/page/$TARGET_ID');ws.onopen=()=>ws.send(d);ws.onmessage=()=>ws.close();"

Interacting with the chat input

The chat textarea has data-testid="chat-input". Use:

agent-browser fill "[data-testid=chat-input]" "Your message here"
agent-browser press Enter                          # submit
sleep 15-30                                        # wait for AI response
agent-browser screenshot /tmp/result.png

Key: fill and type require a selector as the first arg (CSS selector or @ref). Never call type "some text" without a selector — that's keyboard type (different command). When a CSS selector matches multiple elements, use agent-browser snapshot to get unique @ref identifiers.

• Navigate the app as a user would
• Take a screenshot at every meaningful step — the user wants to see what the UI looks like
• Pay special attention to: loading states, error states, empty states, success confirmations
• If testing a flow (e.g., email → rule → draft), wait for async operations to complete before checking results
• Always agent-browser close when done to clean up

Browser authentication

The app requires OAuth login. agent-browser can't complete OAuth, so you need a Chrome profile with an existing logged-in session.

Preferred approach: headless Chrome with a saved profile

The user should have a dedicated Chrome profile directory with a logged-in session (stored outside the repo, e.g. ~/.chrome-debug-inbox-zero). Check the user's auto-memory for the profile path. Then launch Chrome headless and connect:

# 1. Check if CDP is already running
curl -s http://127.0.0.1:9222/json/version

# 2. If not, launch Chrome headless with the saved profile
"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \
  --headless=new \
  --remote-debugging-port=9222 \
  --user-data-dir="$HOME/.chrome-debug-<name>" &>/dev/null &
sleep 3

# 3. Connect agent-browser
agent-browser close
curl -s -X PUT "http://127.0.0.1:9222/json/new?about:blank" > /dev/null
sleep 2
agent-browser --cdp 9222 open http://localhost:3000/automation

This runs entirely in the background — the user doesn't need to do anything.

Important caveats:

• Chrome won't allow two instances with the same --user-data-dir — kill any existing debug Chrome before launching.
• If auth cookies have expired, the user needs to launch Chrome headed (without --headless=new) once to re-login via OAuth, then you can go back to headless.
• Google OAuth blocks agent-browser's built-in Chromium ("This browser or app may not be secure") — must use real Chrome.
• agent-browser may attach to chrome:// internal pages — close those via agent-browser close before connecting.

Fallback options:

1. Connect to user's running Chrome via CDP: If the user already has Chrome open with --remote-debugging-port=9222, just use agent-browser --cdp 9222.
2. Headed mode with profile: Use agent-browser --headed --profile <path> to open a visible Chrome window.
3. State file: After signing in, save with agent-browser state save./auth.json and reload later with agent-browser --state./auth.json. Note: state files can expire.

API testing

• Get a real API key from the UI first (Settings → API Keys) — screenshot the process. Do not test with fake or dummy API keys; auth errors mask whether the actual feature works.
• Configure the CLI/client with the real key, then make real API calls and verify the responses show the expected data.
• Check both success and error cases.

Eval testing

• If the right approach is an eval test, check __tests__/eval/ for existing tests that cover similar ground
• Follow the eval test template in .claude/skills/testing/eval.md
• Use describeEvalMatrix for cross-model comparison when relevant
• Use judgeMultiple with appropriate CRITERIA for subjective outputs
• Run with pnpm test-ai eval/<test-name>

Hybrid approaches

Often the best test combines approaches. For example:

• Use gws to create a Google Drive folder with a test PDF
• Use the browser to configure the feature to use that folder
• Trigger the feature (send an email, start a chat, etc.)
• Verify the result in both the UI (screenshot) and via API/database

Step 4: Report results

An error means the test failed. Do not report success if any step produced an error, even if the error seems like a configuration issue. Either fix the configuration and retry, or report the failure clearly.

Give a clear pass/fail summary:

• What was tested
• What worked
• What failed — with screenshots and the actual error
• What you did to try to fix it

Always include screenshots — even for passing tests. The user wants to see what the UI looks like.

Step 5: Persist (if appropriate)

After testing, ask the user if this should become a reusable test. Two options:

1. Browser QA flow — if the test is primarily UI-driven and would catch regressions, create a flow spec in qa/browser-flows/ following the template. This can then be re-run with /qa-run.
2. Eval test — if the test is about AI output quality, write a proper eval test in __tests__/eval/ that can be run with pnpm test-ai.

Don't persist trivial one-off checks (like "does this page load"). Persist tests that verify important behavior someone might break later.
