# Verify / Webapp Testing Skill

Use when: asked to run the app, verify a fix works, test a feature end-to-end, or confirm behavior before shipping.

## Steps

1. **Identify what to verify** — restate the specific behavior or fix being confirmed.

2. **Start the app** — find the run command (check package.json scripts, README, or ask):
   - `npm run dev`, `npm start`, `python manage.py runserver`, etc.
   - Note the URL/port it starts on.

3. **Define test cases** before opening the browser:
   - Happy path (expected normal use)
   - Edge cases (empty input, max length, no data)
   - Error path (invalid input, network failure if testable)

4. **Execute each test case** — use browser tools or curl:
   - Screenshot or describe what you see
   - Check console for errors (browser devtools or server logs)
   - Verify network requests return expected status/data

5. **Check regression** — does anything that worked before still work?

6. **Report results** clearly:
   - ✅ PASS / ❌ FAIL for each test case
   - Include exact error messages for failures
   - Screenshots or response bodies as evidence

## Rules
- Never mark something as verified without actually running it.
- If the app won't start, fix that first and document what was wrong.
- If a test fails, diagnose root cause before declaring done.
- Log file checks count as verification for server-side behavior.
