Test Strategy for Modern Web Apps (2025)
Pyramid That Works
- Unit: fast and isolated—pure functions and hooks.
- Integration: component + data boundary (mock network, not logic).
- E2E: critical user journeys only.
Keep It Fast
- Run unit/integration in Vitest; E2E in Playwright on CI only.
- Parallelize by folder; cache
node_modulesand Vite.
What Not To Test
- Library internals; test your behavior, not their code.
- Implementation details; focus on outcomes and accessibility.
Less noise, more confidence.
