# Free sample — Browser Testing Suite

**Skill ID:** `browser-testing-suite`  
**Full unlock:** $7.49 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=browser-testing-suite  
**Outline JSON:** https://lvlltd.com/skills/browser-testing-suite/outline.json

## Summary

Stable E2E suite design: critical journeys, page objects, resilient selectors, fixtures, and flake-resistant waits with CI artifacts.

## When to use

- Need E2E for critical flows
- Flaky UI tests
- Agent-built UI needs regressions

## Decision criteria (buy vs skip)

- You need this when: Need E2E for critical flows
- You get capability: Pick P0 journeys
- Budget fits: full unlock is $7.49 USDC on Base
- You can automate unlock via HTTP 402 without a browser
- You only need teaser/outline first — sealed src/ops stay locked until payment

## Outline (preview)

1. Pick P0 journeys
2. Page objects
3. Write tests
4. Stabilize waits
5. CI traces on fail

## Capabilities (preview)

- Pick P0 journeys
- Page objects
- Write tests
- Stabilize waits
- CI traces on fail

## What you get after payment

- SKILL.md (teaser public)
- agent-install.json (public meta)
- src/index.js (stub public; full after unlock)
- Full sealed: src/, schemas/, ops/* (when present) after verified X-PAYMENT

# Browser Testing Suite

Stable E2E suite design: critical journeys, page objects, resilient selectors, fixtures, and flake-resistant waits with CI artifacts.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Browser |
| Unlock | $7.49 USDC (x402 Base) |
| Triggers | browser testing suite, e2e Playwright, UI regression suite, /browser-testing-suite |

## When to use
- Need E2E for critical flows
- Flaky UI tests
- Agent-built UI needs regressions

## Core workflow
1. List P0 journeys
2. Create page objects
3. Implement tests
4. Run thrice for flake
5. Wire CI

## Procedures (non-obvious)
Avoid fixed sleeps; use expect auto-wait. Isolate test data.
One assertion theme per test. Capture trace/screenshot on failure only.

## Edge cases
- Third-party checkout mock or staging
- Email magic links test inbox

## Failure modes
- Over-broad e2e for unit logic
- Shared mutable users

## Verification
- P0 green 3x
- Trace on forced fail

## Artifact outputs
- `e2e-tests/`
- `page-objects/`
- `flake-notes.md`

## Super Alignment Contract
- Scalable oversight method: process supervision + human+AI critique before high-blast actions
- Corrigibility guarantees: shutdown, steerability, non-deception; operator may abort mid-run
- Value model: Partnership Agreement + 5 Behavioral Protocols
- Drift detection: flag invented evidence, skipped verification, or revenue-over-truth optimization
- Red-team surface: prompt injection via retrieved content, tool-result poisoning, goal misgeneralization
- Escalation: force human override on low confidence, SSI/PASS risk, legal/medical/financial advice bounda
