-## Jest Configuration
-
-```javascript
-// jest.config.js
-const nextJest = require('next/jest');
-
-const createJestConfig = nextJest({
- dir: './',
-});
-
-const customJestConfig = {
- setupFilesAfterEnv: ['<rootDir>/jest.setup.js'],
- testEnvironment: 'jest-environment-jsdom',
- moduleNameMapper: {
- '^@/(.*)$': '<rootDir>/src/$1',
- },
- testPathIgnorePatterns: ['<rootDir>/.next/', '<rootDir>/node_modules/'],
- moduleDirectories: ['node_modules', '<rootDir>/'],
- collectCoverageFrom: [
- 'app/**/*.{js,jsx,ts,tsx}',
- 'src/**/*.{js,jsx,ts,tsx}',
- '!**/*.d.ts',
- '!**/node_modules/**',
- '!**/.next/**',
- ],
-};
-
-module.exports = createJestConfig(customJestConfig);
-```
-
-```javascript
-// jest.setup.js
-import '@testing-library/jest-dom';
-
-// Mock Next.js modules
-jest.mock('next/navigation', () => ({
- useRouter: () => ({
- push: jest.fn(),
- replace: jest.fn(),
- prefetch: jest.fn(),
- }),
- useSearchParams: () => ({
- get: jest.fn(),
- }),
- usePathname: () => '/test-path',
-}));
-```
-
-## Vitest Configuration
-
-```typescript
-// vitest.config.ts
-import { defineConfig } from 'vitest/config';
-import react from '@vitejs/plugin-react';
-import path from 'path';
-
-export default defineConfig({
- plugins: [react()],
- test: {
- environment: 'jsdom',
- setupFiles: ['./vitest.setup.ts'],
- globals: true,
- css: true,
- },
- resolve: {
- alias: {
- '@': path.resolve(__dirname, './src'),
- },
- },
-});
-```
-
-## Testing Client Components
-
-```typescript
-// __tests__/Button.test.tsx
-import { render, screen, fireEvent } from '@testing-library/react';
-import { Button } from '@/components/Button';
-
-describe('Button', () => {
- it('renders with text', () => {
- render(<Button>Click me</Button>);
- expect(screen.getByRole('button')).toHaveTextContent('Click me');
- });
-
- it('handles click events', () => {
- const handleClick = jest.fn();
- render(<Button onClick={handleClick}>Click me</Button>);
-
- fireEvent.click(screen.getByRole('button'));
- expect(handleClick).toHaveBeenCalledTimes(1);
- });
-
- it('can be disabled', () => {
- render(<Button disabled>Click me</Button>);
- expect(screen.getByRole('button')).toBeDisabled();
- });
-});
-```
-
-## Testing Server Components (Limited)
-
-```typescript
-// Server Components have limitations in unit tests
-// Test the logic separately or use E2E tests
-
-// lib/data.ts
-export async function getProducts() {
- const res = await fetch('https://api.example.com/products');
- return res.json();
-}
-
-// __tests__/data.test.ts
-import { getProducts } from '@/lib/data';
-
-// Mock fetch
-global.fetch = jest.fn();
-
-describe('getProducts', () => {
- it('fetches products successfully', async () => {
- const mockProducts = [{ id: 1, name: 'Product 1' }];
-
- (fetch as jest.Mock).mockResolvedValueOnce({
- json: async () => mockProducts,
- });
-
- const products = await getProducts();
- expect(products).toEqual(mockProducts);
- });
-});
-```
-
-## Testing Server Actions
-
-```typescript
-// __tests__/actions.test.ts
-import { createUser } from '@/app/actions';
-import { db } from '@/lib/db';
-
-jest.mock('@/lib/db');
-jest.mock('next/cache', () => ({
- revalidatePath: jest.fn(),
-}));
-jest.mock('next/navigation', () => ({
- redirect: jest.fn(),
-}));
-
-describe('createUser Server Action', () => {
- it('creates user with valid data', async () => {
- const formData = new FormData();
- formData.append('email', 'test@example.com');
- formData.append('name', 'Test User');
-
- (db.user.create as jest.Mock).mockResolvedValueOnce({
- id: '1',
- email: 'test@example.com',
- name: 'Test User',
- });
-
- await createUser({}, formData);
-
- expect(db.user.create).toHaveBeenCalledWith({
- data: {
- email: 'test@example.com',
- name: 'Test User',
- },
- });
- });
-
- it('returns errors for invalid data', async () => {
- const formData = new FormData();
- formData.append('email', 'invalid-email');
- formData.append('name', '');
-
- const result = await createUser({}, formData);
-
- expect(result.errors).toBeDefined();
- expect(result.errors.email).toBeDefined();
- expect(result.errors.name).toBeDefined();
- });
-});
-```
-
-## Playwright E2E Testing
-
-```typescript
-// playwright.config.ts
-import { defineConfig, devices } from '@playwright/test';
-
-export default defineConfig({
- testDir: './e2e',
- fullyParallel: true,
- forbidOnly: !!process.env.CI,
- retries: process.env.CI ? 2 : 0,
- workers: process.env.CI ? 1 : undefined,
- reporter: 'html',
- use: {
- baseURL: 'http://localhost:3000',
- trace: 'on-first-retry',
- },
- projects: [
- {
- name: 'chromium',
- use: { ...devices['Desktop Chrome'] },
- },
- ],
- webServer: {
- command: 'npm run dev',
- url: 'http://localhost:3000',
- reuseExistingServer: !process.env.CI,
- },
-});
-```
-
-```typescript
-// e2e/app.spec.ts
-import { test, expect } from '@playwright/test';
-
-test.describe('Navigation', () => {
- test('should navigate to about page', async ({ page }) => {
- await page.goto('/');
-
- await page.click('text=About');
- await expect(page).toHaveURL('/about');
- await expect(page.locator('h1')).toContainText('About');
- });
-});
-
-test.describe('Form Submission', () => {
- test('should submit form successfully', async ({ page }) => {
- await page.goto('/contact');
-
- await page.fill('input[name="email"]', 'test@example.com');
- await page.fill('input[name="message"]', 'Test message');
- await page.click('button[type="submit"]');
-
- await expect(page.locator('.success-message')).toBeVisible();
- });
-});
-```
-
-## Cypress Integration Testing
-
-```javascript
-// cypress.config.js
-const { defineConfig } = require('cypress');
-
-module.exports = defineConfig({
- e2e: {
- baseUrl: 'http://localhost:3000',
- supportFile: 'cypress/support/e2e.js',
- specPattern: 'cypress/e2e/**/*.cy.{js,jsx,ts,tsx}',
- },
- component: {
- devServer: {
- framework: 'next',
- bundler: 'webpack',
- },
- specPattern: 'cypress/component/**/*.cy.{js,jsx,ts,tsx}',
- },
-});
-```
-
-```typescript
-// cypress/e2e/navigation.cy.ts
-describe('Navigation', () => {
- it('should navigate between pages', () => {
- cy.visit('/');
-
- cy.contains('About').click();
- cy.url().should('include', '/about');
-
- cy.contains('Products').click();
- cy.url().should('include', '/products');
- });
-});
-```
-
-## Testing Hooks
-
-```typescript
-// __tests__/hooks/useCounter.test.ts
-import { renderHook, act } from '@testing-library/react';
-import { useCounter } from '@/hooks/useCounter';
-
-describe('useCounter', () => {
- it('increments counter', () => {
- const { result } = renderHook(() => useCounter());
-
- act(() => {
- result.current.increment();
- });
-
- expect(result.current.count).toBe(1);
- });
-});
-```
-
-## Testing API Routes
-
-```typescript
-// __tests__/api/hello.test.ts
-import { GET } from '@/app/api/hello/route';
-import { NextRequest } from 'next/server';
-
-describe('/api/hello', () => {
- it('returns hello message', async () => {
- const request = new NextRequest('http://localhost/api/hello');
- const response = await GET(request);
- const data = await response.json();
-
- expect(response.status).toBe(200);
- expect(data).toEqual({ message: 'Hello, World!' });
- });
-});
-```
-
-## Test Commands
-
-```json
-// package.json
-{
- "scripts": {
- "test": "jest",
- "test:watch": "jest --watch",
- "test:coverage": "jest --coverage",
- "test:e2e": "playwright test",
- "test:e2e:ui": "playwright test --ui",
- "test:cypress": "cypress open",
- "test:cypress:headless": "cypress run"
- }
-}
-```
-
-## CI/CD Integration
-
-```yaml
-# .github/workflows/test.yml
-name: Tests
-on: [push, pull_request]
-
-jobs:
- test:
- runs-on: ubuntu-latest
- steps:
- - uses: actions/checkout@v3
- - uses: actions/setup-node@v3
- with:
- node-version: '20'
- - run: npm ci
- - run: npm run test:coverage
- - run: npx playwright install
- - run: npm run test:e2e
-```
-
-## Best Practices
-
-1. Test user behavior, not implementation details
-2. Use data-testid for reliable element selection
-3. Mock external dependencies appropriately
-4. Write E2E tests for critical user journeys
-5. Keep unit tests fast and focused
-6. Use proper async handling in tests
-7. Test error states and edge cases
-8. Maintain good test coverage (aim for 80%+)
-
-Always ensure tests are deterministic, isolated, and provide clear failure messages.
