Explain end-to-end testing using Cypress or Selenium.
Pyramid in 2026: many unit tests (pure logic, Vitest/Jest), more integration tests than people expect (component + MSW mocked network, React Testing Library), small E2E suite for top-3 user journeys (Playwright). Test behavior not implementation. Visual regression on key screens. Run the right suite at the right gate — unit pre-push, integration on PR, E2E on main/staging.
