+- Yarn or npm
+
+### Installation
+
+```bash
+yarn install
+# or
+npm install
+```
+
+### Available Scripts
+
+- `npm run dev` - Start development server
+- `npm run build` - Build for production
+- `npm run lint` - Run ESLint
+- `npm run preview` - Preview production build
+- `npm test` - Run unit tests
+- `npm run test:ui` - Run unit tests with UI
+- `npm run test:e2e` - Run E2E tests (requires Playwright browsers)
+
+## Testing
+
+This project includes comprehensive test coverage:
+
+- **Unit Tests**: Using Vitest and React Testing Library
+- **E2E Tests**: Using Playwright
+
+For detailed testing documentation, see [TESTING.md](./TESTING.md).

+# Testing Guide
+
+This project includes both unit tests and E2E tests.
+
+## Unit Tests
+
+Unit tests are written using [Vitest](https://vitest.dev/) and [React Testing Library](https://testing-library.com/react).
+
+### Running Unit Tests
+
+```bash
+# Run tests once
+npm test
+
+# Run tests in watch mode
+npm test -- --watch
+
+# Run tests with UI
+npm run test:ui
+
+# Run tests with coverage
+npm run test:coverage
+```
+
+### Test Files
+
+- `src/App.test.tsx` - Tests for the main App component and cellRender function
+
+### Writing Unit Tests
+
+Unit tests should be placed next to the components they test, with a `.test.tsx` extension.
+
+Example:
+```typescript
+import { describe, it, expect } from 'vitest'
+import { render, screen } from '@testing-library/react'
+import MyComponent from './MyComponent'
+
+describe('MyComponent', () => {
+  it('renders correctly', () => {
+    render(<MyComponent />)
+    expect(screen.getByText('Expected Text')).toBeInTheDocument()
+  })
+})
+```
+
+## E2E Tests
+
+E2E tests are written using [Playwright](https://playwright.dev/).
+
+### Running E2E Tests
+
+First, install the Playwright browsers:
+
+```bash
+npx playwright install
+```
+
+Then run the tests:
+
+```bash
+# Run E2E tests
+npm run test:e2e
+
+# Run E2E tests with UI
+npm run test:e2e:ui
+```
+
+### Test Files
+
+- `e2e/app.spec.ts` - E2E tests for the calendar application
+
+### Writing E2E Tests
+
+E2E tests should be placed in the `e2e/` directory with a `.spec.ts` extension.
+
+Example:
+```typescript
+import { test, expect } from '@playwright/test'
+
+test('should display the page', async ({ page }) => {
+  await page.goto('/optimax-prime/')
+  await expect(page.getByText('Expected Text')).toBeVisible()
+})
+```
+
+## Test Configuration
+
+- `vitest.config.ts` - Configuration for Vitest unit tests
+- `playwright.config.ts` - Configuration for Playwright E2E tests
+- `src/test/setup.ts` - Test setup file for Vitest
+
+## Continuous Integration
+
+Both unit tests and E2E tests can be run in CI/CD pipelines. The E2E tests will automatically build and serve the application before running the tests.
