# Web Testing Skill

Comprehensive web testing: unit, integration, E2E, load, security, visual regression, accessibility.

## Quick Start

```bash
npx vitest run                    # Unit tests
npx playwright test               # E2E tests
npx playwright test --ui          # E2E with UI
k6 run load-test.js               # Load tests
npx @axe-core/cli https://example.com  # Accessibility
npx lighthouse https://example.com     # Performance
```
