| Alternativa | Scope | Speed | Best for |
|---|---|---|---|
| ★Playwright | E2E | Slow (real browser) | Critical user flows |
| Vitest | Unit / integration | Very fast | Logic & component unit tests |
| Cypress | E2E | Moderate | Interactive E2E debugging |
| Testing Library | Component | Fast | Accessible component tests |
