Stratégie de Tests React 19 + Compiler 1.0

Versions : React 19.2+ | React Compiler 1.0 | Vitest 4.1+ | Playwright

React Compiler 1.0 (auto-memoization) est transparent pour les tests — tester le comportement visible, jamais les optimisations internes.

Stack recommandée 2026

Type	Outil	Usage
Unit/Composants	Vitest 4.1+ Browser Mode	Chromium/Firefox/WebKit natif
Component Testing	Playwright CT	Alternative à RTL — browser réel
E2E	Playwright	Flows utilisateur complets
Mutation	Stryker	Qualité des tests (score >= 80%)
Property-based	fast-check	Génération de cas de test

Abandonner : JSDOM (lourd, incomplet) et React Testing Library (remplacé par Playwright CT).
