+# Use Vitest for Vue 3 Testing - Recommended by Vue Team
+
+**Impact: MEDIUM** - Vitest is created and maintained by Vue/Vite team members and shares the same configuration and transform pipeline as Vite. Using Jest or other test runners with Vite-based projects requires additional configuration and can result in slower test execution and compatibility issues.
+
+Use Vitest for new Vue 3 projects. Only consider Jest if migrating an existing test suite.
+
+## Task Checklist
+
+- [ ] Install Vitest and related packages for Vue testing
+- [ ] Configure vitest in vite.config.js or vitest.config.js
+- [ ] Set up proper test environment (happy-dom or jsdom)
+- [ ] Add test scripts to package.json
+- [ ] Configure globals if desired for cleaner test syntax
+- [ ] Use @vue/test-utils for component mounting
+
+## Quick Setup
+
+```bash
+# Install required packages
+npm install -D vitest @vue/test-utils happy-dom
+# or with jsdom
+npm install -D vitest @vue/test-utils jsdom
+```
+
+**vite.config.js:**
+```javascript
+import { defineConfig } from 'vite'
+import vue from '@vitejs/plugin-vue'
+
+export default defineConfig({
+  plugins: [vue()],
+  test: {
+    // Enable global test APIs (describe, it, expect)
+    globals: true,
+    // Use happy-dom for faster tests (or 'jsdom' for better compatibility)
+    environment: 'happy-dom',
+    // Optional: Setup files for global configuration
+    setupFiles: ['./src/test/setup.js']
+  }
+})
+```
+
+**package.json:**
+```json
+{
+  "scripts": {
+    "test": "vitest",
+    "test:run": "vitest run",
+    "test:coverage": "vitest run --coverage"
+  }
+}
+```
+
+**tsconfig.json (if using TypeScript):**
+```json
+{
+  "compilerOptions": {
+    "types": ["vitest/globals"]
+  }
+}
+```
+
+## Test File Example
+
+```javascript
+// src/components/Counter.test.js
+import { describe, it, expect, beforeEach } from 'vitest'  // optional with globals: true
+import { mount } from '@vue/test-utils'
+import Counter from './Counter.vue'
+
+describe('Counter', () => {
+  let wrapper
+
+  beforeEach(() => {
+    wrapper = mount(Counter)
+  })
+
+  it('renders initial count', () => {
+    expect(wrapper.find('[data-testid="count"]').text()).toBe('0')
+  })
+
+  it('increments when button clicked', async () => {
+    await wrapper.find('[data-testid="increment"]').trigger('click')
+    expect(wrapper.find('[data-testid="count"]').text()).toBe('1')
+  })
+})
+```
+
+## Vitest vs Jest Comparison
+
+| Feature | Vitest | Jest |
+|---------|--------|------|
+| Vite Integration | Native | Requires config |
+| Speed | Very fast (ESM native) | Slower with Vite |
+| Watch Mode | Excellent | Good |
+| Vue SFC Support | Works with Vite | Needs vue-jest |
+| Config Sharing | Same as vite.config | Separate |
+| API | Jest-compatible | Standard |
+
+## Using with Testing Library
+
+```bash
+npm install -D @testing-library/vue @testing-library/jest-dom
+```
+
+```javascript
+// src/test/setup.js
+import { expect } from 'vitest'
+import * as matchers from '@testing-library/jest-dom/matchers'
+
+expect.extend(matchers)
+```
+
+```javascript
+// Component.test.js
+import { render, screen, fireEvent } from '@testing-library/vue'
+import UserCard from './UserCard.vue'
+
+test('displays user name', () => {
+  render(UserCard, {
+    props: { name: 'John Doe' }
+  })
+
+  expect(screen.getByText('John Doe')).toBeInTheDocument()
+})
+```
+
+## Advanced Configuration
+
+```javascript
+// vitest.config.js (separate file if preferred)
+import { defineConfig } from 'vitest/config'
+import vue from '@vitejs/plugin-vue'
+
+export default defineConfig({
+  plugins: [vue()],
+  test: {
+    globals: true,
+    environment: 'happy-dom',
+    include: ['**/*.{test,spec}.{js,ts,jsx,tsx}'],
+    exclude: ['node_modules', 'dist', 'e2e'],
+    coverage: {
+      provider: 'v8',
+      reporter: ['text', 'json', 'html'],
+      exclude: ['node_modules', 'test']
+    },
+    // Helpful for debugging
+    reporters: ['verbose'],
+    // Run tests in sequence in CI
+    poolOptions: {
+      threads: {
+        singleThread: process.env.CI === 'true'
+      }
+    }
+  }
+})
+```
+
+## Common Patterns
+
+### Mocking Modules
+```javascript
+import { vi } from 'vitest'
+
+vi.mock('@/api/users', () => ({
+  fetchUser: vi.fn().mockResolvedValue({ name: 'John' })
+}))
+```
+
+### Testing with Fake Timers
+```javascript
+import { vi, beforeEach, afterEach } from 'vitest'
+
+beforeEach(() => {
+  vi.useFakeTimers()
+})
+
+afterEach(() => {
+  vi.restoreAllMocks()
+})
+
+test('debounced search', async () => {
+  const wrapper = mount(SearchBox)
+  await wrapper.find('input').setValue('vue')
+
+  vi.advanceTimersByTime(300)
+  await flushPromises()
+
+  expect(wrapper.emitted('search')).toBeTruthy()
+})
+```
