+# Test Setup Guide
+
+This document explains how to set up and run tests for the analytics and brand settings components.
+
+## Prerequisites
+
+To run the tests, you'll need to install testing dependencies:
+
+```bash
+npm install --save-dev @testing-library/react @testing-library/jest-dom @testing-library/user-event vitest jsdom
+```
+
+## Test Configuration
+
+Create a `vitest.config.ts` file in the Frontend directory:
+
+```typescript
+import { defineConfig } from 'vitest/config'
+import react from '@vitejs/plugin-react'
+import path from 'path'
+
+export default defineConfig({
+ plugins: [react()],
+ test: {
+ globals: true,
+ environment: 'jsdom',
+ setupFiles: ['./src/test-setup.ts'],
+ },
+ resolve: {
+ alias: {
+ '@': path.resolve(__dirname, './src'),
+ },
+ },
+})
+```
+
+Create a `src/test-setup.ts` file:
+
+```typescript
+import '@testing-library/jest-dom'
+
+// Mock localStorage
+const localStorageMock = {
+ getItem: jest.fn(),
+ setItem: jest.fn(),
+ removeItem: jest.fn(),
+ clear: jest.fn(),
+};
+global.localStorage = localStorageMock;
+
+// Mock window.matchMedia
+Object.defineProperty(window, 'matchMedia', {
+ writable: true,
+ value: jest.fn().mockImplementation(query => ({
+ matches: false,
+ media: query,
+ onchange: null,
+ addListener: jest.fn(), // deprecated
+ removeListener: jest.fn(), // deprecated
+ addEventListener: jest.fn(),
+ removeEventListener: jest.fn(),
+ dispatchEvent: jest.fn(),
+ })),
+});
+```
+
+## Running Tests
+
+Add test scripts to your `package.json`:
+
+```json
+{
+ "scripts": {
+ "test": "vitest",
+ "test:ui": "vitest --ui",
+ "test:run": "vitest run",
+ "test:coverage": "vitest run --coverage"
+ }
+}
+```
+
+Run tests:
+
+```bash
+# Run all tests
+npm test
+
+# Run tests in watch mode
+npm run test
+
+# Run tests once
+npm run test:run
+
+# Run tests with coverage
+npm run test:coverage
+
+# Run tests with UI
+npm run test:ui
+```
+
+## Test Files
+
+The following test files have been created:
+
+### Analytics Components
+- `src/components/analytics/__tests__/performance-overview.test.tsx`
+- `src/components/analytics/__tests__/metrics-chart.test.tsx`
+
+### Content Components
+- `src/components/content/__tests__/content-linking.test.tsx`
+
+### Brand Components
+- `src/components/brand/__tests__/social-account-connection.test.tsx`
+
+### Pages
+- `src/pages/__tests__/Analytics.test.tsx`
+
+## Test Coverage
+
+The tests cover:
+
+1. **Component Rendering**: Ensures components render correctly with different props
+2. **User Interactions**: Tests button clicks, form submissions, and user input
+3. **State Management**: Verifies component state changes and updates
+4. **Error Handling**: Tests error scenarios and fallback behavior
+5. **Loading States**: Ensures loading indicators work correctly
+6. **API Integration**: Mocks API calls and tests response handling
+
+## Mocking Strategy
+
+The tests use various mocking strategies:
+
+- **External Libraries**: Recharts, Sonner toast notifications
+- **API Calls**: Fetch requests with different response scenarios
+- **Browser APIs**: localStorage, window.open, URL.createObjectURL
+- **React Context**: Auth context for user authentication
+- **Component Dependencies**: Child components are mocked for isolation
+
+## Best Practices
+
+1. **Isolation**: Each test is independent and doesn't rely on others
+2. **Cleanup**: Tests clean up after themselves using beforeEach/afterEach
+3. **Realistic Data**: Tests use realistic mock data that matches expected formats
+4. **Error Scenarios**: Tests include both success and error cases
+5. **Accessibility**: Tests use accessible queries when possible
+6. **Performance**: Tests are fast and don't make real network requests
+
+## Troubleshooting
+
+Common issues and solutions:
+
+1. **Import Errors**: Ensure path aliases are configured correctly in vitest.config.ts
+2. **Component Not Found**: Check that components are exported correctly
+3. **Mock Issues**: Verify mocks are cleared between tests
+4. **Async Issues**: Use waitFor for async operations
+5. **DOM Issues**: Ensure jsdom environment is configured
+
+## Future Improvements
+
+Consider adding:
+
+1. **E2E Tests**: Cypress or Playwright for full user workflows
+2. **Visual Regression Tests**: Chromatic or similar for UI consistency
+3. **Performance Tests**: Bundle size and runtime performance monitoring
+4. **Integration Tests**: Test component interactions with real APIs
+5. **Accessibility Tests**: Automated a11y testing with jest-axe
