Create reusable data builders (user, quiz, course) and mock utilities (session, router, axios) to reduce duplication in future tests.
Remove duplicate MockEventSource from useGenerationProgress test and use the shared one from setup.ts. Add instance tracking and simulateProgressEvent helper to the shared mock.
Add GitHub Actions workflow that runs unit tests on PRs and posts a sticky coverage comment via vitest-coverage-report-action. Add json-summary reporter and expanded coverage exclusions to vitest config. Add test:ci script for non-watch CI execution.
…nd improve caching
Lucide icons inside <label> elements were polluting accessible names, preventing screen readers and Playwright from matching label text correctly.
… job - Fix selectors to match actual UI (getByRole, getByPlaceholder) - Remove conditional tests and arbitrary waits - Fix routes to match real app structure - Add E2E job to CI workflow (build + chromium + report artifact) - Move permissions to job level (SonarQube compliance) - Configure Playwright for CI (pnpm start instead of dev)
- quiz: shuffleArray immutability, shuffleQuiz answer preservation (11 tests) - subscription-helpers: getSubscriptionStatus all branches, formatSubscriptionDate (12 tests) - role-permissions: canUserModifyTicket/canUserReopenTicket per role (11 tests) - auth-utils: isTokenExpired, getCurrentUserId id/_id fallback, isAuthenticated, getAuthHeaders (15 tests)
- useUserStatistics: stats computation, score distribution, trend, streaks, weekly activity, period filtering (23 tests) - useQuizPlayer: initialization, answer submission, navigation, restart, insight creation, edge cases (17 tests)
ResizeObserver mock needed for Radix UI components in jsdom. user-event enables realistic user interaction testing in RTL.
Reference implementations for the team to follow when adding component tests: - AuthGuard: conditional rendering based on hook state (6 tests) - SigninForm: form validation, submit flow, password toggle, callbacks (11 tests) - SignupForm: registration validation, password requirements, error handling (9 tests) Each file documents the RTL pattern used (mock hooks, userEvent.setup, waitFor).
- docs/TESTING.md: architecture, patterns for each test type, commands - README.md: add test commands section with link to guide

Summary
Set up the complete testing infrastructure for the project: Vitest + React Testing Library for unit/component tests, Playwright for E2E, and a CI workflow to run everything automatically. Includes reference test examples for each category (pure functions, hooks, components, E2E) to serve as a base for the team.
