We use ESLint to maintain code quality and catch errors early.

To check for linting errors:

npm run lint

We recommend adopting the following stack for future testing implementation:

1. Vitest: Fast unit test runner, compatible with Vite.
2. React Testing Library: For testing components in a way that resembles user usage.
3. Cypress or Playwright: For End-to-End (E2E) testing.

1. Install: npm i -D vitest @testing-library/react jsdom
2. Configure vite.config.ts: add test environment.
3. Run: npx vitest

Until automated tests are fully in place, please manually verify:

1. Authentication Flow: Login, Register, Logout.
2. Responsiveness: Check UI on Mobile vs Desktop.
3. Forms: Validation errors appear correctly on invalid input.
4. Theme: Dark/Light mode toggle (if applicable).
