+# End-to-End Test Suite for PromptAid Vision
+
+This directory contains comprehensive end-to-end tests that validate the complete user experience through the entire application stack.
+
+## 🎯 Overview
+
+These are **true E2E tests** that:
+- ✅ Hit the running app over HTTP via real browsers
+- ✅ Test complete user workflows from start to finish
+- ✅ Validate frontend, backend, and database integration
+- ✅ Use real browser automation with Playwright
+- ✅ Run against containerized services
+
+## 🏗️ Architecture

+```
+
+## 🚀 Quick Start
+
+### Prerequisites
+- Docker and Docker Compose
+- Python 3.8+
+- Git
+
+### Run E2E Tests
+
+```bash
+# Option 1: Use the automated script
+chmod +x run_e2e_tests.sh
+./run_e2e_tests.sh
+
+# Option 2: Manual steps
+docker-compose -f docker-compose.e2e.yml up -d --build
+pip install -r requirements.txt
+playwright install
+pytest -m e2e -v
+docker-compose -f docker-compose.e2e.yml down -v
+```
+
+## 🧪 Test Categories
+
+### 1. Upload Flow Tests (`upload_flow_spec.py`)
+- **Complete upload workflow**: File selection → Analysis → Success
+- **Invalid file handling**: Error messages for wrong file types
+- **Large file handling**: Performance with large images
+
+### 2. Admin Settings Tests (`admin_settings_spec.py`)
+- **Authentication flow**: Login/logout with correct/incorrect credentials
+- **Schema management**: Admin interface for schema configuration
+- **Model configuration**: VLM service configuration
+- **System monitoring**: Health checks and monitoring
+
+### 3. Export Tests (`export_spec.py`)
+- **Filtered data export**: Export with applied filters
+- **Bulk export workflow**: Export multiple selected items
+- **Export format validation**: Different export formats
+- **Performance testing**: Export with large datasets
+
+## 🔧 Environment Setup
+
+### Docker Services
+- **PostgreSQL 16**: Test database with health checks
+- **MinIO**: S3-compatible storage for file uploads
+- **Backend**: FastAPI with mock VLM provider
+- **Frontend**: React application with Vite
+
+### Health Checks
+- Backend: `http://localhost:7860/health`
+- Frontend: `http://localhost:3000`
+- Database: PostgreSQL connection check
+- MinIO: S3 health endpoint
+
+## 📊 Test Metrics
+
+### What We Measure
+- **Flakiness rate**: Test stability and reliability
+- **Test duration**: Median and 95th percentile times
+- **Critical path coverage**: Key user workflows
+- **Failure triage speed**: Debug information availability
+
+### What We Don't Measure
+- ❌ Code coverage (not relevant for E2E)
+- ❌ Individual test duration targets
+- ❌ UI element coverage percentages
+
+## 🎭 Playwright Configuration
+
+### Browser Settings
+- **Viewport**: 1920x1080
+- **Video recording**: Enabled for all tests
+- **Screenshots**: On failure
+- **Traces**: Available for debugging
+
+### Auto-wait Strategy
+- No explicit `sleep()` calls
+- Uses Playwright's built-in auto-wait
+- Relies on `expect().toBeVisible()` assertions
+- URL-based navigation verification
+
+## 📁 Test Data Management
+
+### Data Isolation
+- **Per-test reset**: `/test/reset` endpoint (E2E mode only)
+- **Volume cleanup**: `docker-compose down -v` after suite
+- **Namespaced data**: Unique filenames per test
+
+### Test Fixtures
+- Sample images for upload testing
+- Test schemas for validation
+- Mock data for various scenarios
+
+## 🚨 Troubleshooting
+
+### Common Issues
+
+1. **Services not ready**
+   ```bash
+   # Check service health
+   curl http://localhost:7860/health
+   curl http://localhost:3000
+   ```
+
+2. **Browser installation issues**
+   ```bash
+   # Reinstall Playwright browsers
+   playwright install
+   ```
+
+3. **Test failures with traces**
+   ```bash
+   # View test traces
+   playwright show-trace test-results/trace.zip
+   ```
+
+### Debug Mode
+```bash
+# Run tests with headed browser
+pytest -m e2e --headed --slowmo=1000
+
+# Run specific test with debugging
+pytest specs/upload_flow_spec.py::TestUploadFlow::test_complete_upload_flow -v --headed
+```
+

+          path: e2e/test-results/
+```
+
+## 📋 Test Results
+
+### Output Locations
+- **Videos**: `test-results/videos/`
+- **Screenshots**: `test-results/screenshots/`
+- **Traces**: `test-results/har/`
+- **Reports**: Playwright HTML report
+
+### Success Criteria
+- All critical user paths covered
+- <5% flakiness rate
+- <5 minutes total suite duration
+- Clear failure debugging information
+
+## 🔄 Maintenance
+
+### Regular Tasks
+- Update test selectors when UI changes
+- Refresh test data periodically
+- Monitor flakiness trends
+- Update dependencies
+
+### Best Practices
+- Use stable `data-testid` selectors
+- Keep page objects thin and focused
+- Write descriptive test names
+- Maintain test data isolation

+# Testing Guide
+
+This project uses Vitest for unit testing with React Testing Library for component testing.
+
+## Available Scripts
+
+- `npm test` - Run tests in watch mode
+- `npm run test:run` - Run tests once
+- `npm run test:ui` - Run tests with UI (requires @vitest/ui)
+- `npm run test:coverage` - Run tests with coverage report
+
+## Test File Structure
+
+- Test files should be named `ComponentName.test.tsx` or `ComponentName.spec.tsx`
+- Place test files alongside the components they test
+- Use the `src/test/` directory for test utilities and setup
+
+## Writing Tests
+
+### Basic Component Test
+```tsx
+import { render, screen } from '../test/test-utils'
+import { describe, it, expect } from 'vitest'
+import MyComponent from './MyComponent'
+
+describe('MyComponent', () => {
+  it('renders without crashing', () => {
+    render(<MyComponent />)
+    expect(screen.getByText('Hello')).toBeInTheDocument()
+  })
+})
+```
+
+### Testing User Interactions
+```tsx
+import { fireEvent } from '../test/test-utils'
+
+it('responds to button clicks', () => {
+  render(<MyComponent />)
+  const button = screen.getByRole('button')
+  fireEvent.click(button)
+  expect(screen.getByText('Clicked!')).toBeInTheDocument()
+})
+```
+
+### Testing with Context
+Use the custom `render` function from `test-utils.tsx` to automatically wrap components with necessary providers.
+
+## Mocking
+
+### Mocking External Dependencies
+```tsx
+vi.mock('react-router-dom', () => ({
+  useNavigate: () => vi.fn(),
+  Link: ({ children, to }: { children: React.ReactNode; to: string }) => (
+    <a href={to}>{children}</a>
+  ),
+}))
+```
+
+### Mocking API Calls
+```tsx
+vi.mock('../services/api', () => ({
+  fetchData: vi.fn(() => Promise.resolve({ data: 'test' }))
+}))
+```
+
+## Best Practices
+
+1. Test behavior, not implementation
+2. Use semantic queries (getByRole, getByLabelText) over getByTestId
+3. Write tests that resemble how users interact with your app
+4. Keep tests focused and isolated
+5. Use descriptive test names that explain the expected behavior
+
+## Running Specific Tests
+
+```bash
+# Run tests matching a pattern
+npm test -- --grep "FilterBar"
+
+# Run tests in a specific file
+npm test HeaderNav.test.tsx
+
+# Run tests with verbose output
+npm test -- --reporter=verbose
+```

+# Frontend Integration Tests
+
+This directory contains integration tests that verify how different components work together in the PromptAid Vision frontend application.
+
+## 🎯 What are Integration Tests?
+
+Integration tests verify that:
+- **Components interact correctly** with each other
+- **Context providers** work with their consumers
+- **Routing** functions properly between components
+- **State management** flows correctly through the app
+- **User workflows** work end-to-end across multiple components
+
+## 📁 Test Files
+
+### 1. **FilterBarWithFilterContext.test.tsx** (4 tests)
+Tests the integration between `FilterBar` component and `FilterContext`:
+- Filter updates trigger context changes
+- Clear button resets context
+- Loading states are properly displayed
+- Current filters are shown from context
+
+### 2. **HeaderNavWithRouting.test.tsx** (5 tests)
+Tests the integration between `HeaderNav` component and routing:
+- Logo click navigates to explore page
+- Help link navigation works
+- Admin link visibility based on user role
+- Current page highlighting
+
+### 3. **ExportModalWithAdminContext.test.tsx** (8 tests)
+Tests the integration between `ExportModal` component and `AdminContext`:
+- Admin-only features visibility
+- Image selection handling
+- Export button states
+- Modal interactions
+
+### 4. **HelpPageWithRouting.test.tsx** (7 tests)
+Tests the integration between `HelpPage` component and routing:
+- All help sections are displayed
+- Back button navigation
+- Admin-specific help visibility
+- Contact information display
+
+### 5. **AppWorkflow.test.tsx** (6 tests)
+Tests complete application workflows:
+- Complete user workflow (navigate, filter, export)
+- Admin workflow (access admin features)
+- Filter workflow (apply and clear filters)
+- Navigation workflow (page transitions)
+- Context integration (filters and admin state)
+- Error handling workflow
+
+## 🚀 Running Integration Tests
+
+### Run All Integration Tests
+```bash
+npm run test:integration
+```
+
+### Run Specific Integration Test
+```bash
+npx vitest run src/test/integration/FilterBarWithFilterContext.test.tsx
+```
+
+### Run in Watch Mode
+```bash
+npx vitest src/test/integration --reporter=verbose
+```
+
+## 🧪 Test Structure
+
+Each integration test follows this pattern:
+
+```typescript
+describe('Component + Context Integration', () => {
+  beforeEach(() => {
+    // Setup mocks and reset state
+  });
+
+  test('Specific integration scenario', async () => {
+    // Render components with providers
+    // Simulate user interactions
+    // Verify component interactions
+    // Check context state changes
+  });
+});
+```
+
+## 🔧 Mocking Strategy
+
+Integration tests use strategic mocking:
+
+- **Context Hooks**: Mock `useFilterContext` and `useAdminContext`
+- **Routing**: Mock `useNavigate` and `useLocation`
+- **External Libraries**: Mock `jszip` for export functionality
+- **Component Dependencies**: Mock child components when needed
+
+## 📊 Test Coverage
+
+Integration tests cover:
+
+| Component | Context Integration | Routing Integration | Workflow Integration |
+|-----------|-------------------|-------------------|-------------------|
+| FilterBar | ✅ FilterContext | ❌ | ❌ |
+| HeaderNav | ✅ AdminContext | ✅ React Router | ❌ |
+| ExportModal | ✅ AdminContext | ❌ | ❌ |
+| HelpPage | ✅ AdminContext | ✅ React Router | ❌ |
+| App Workflow | ✅ All Contexts | ✅ React Router | ✅ Complete Workflows |
+
+## 🎭 Test Scenarios
+
+### User Workflows
+1. **Filter and Export**: Apply filters → Select images → Export data
+2. **Navigation**: Move between pages → Use back buttons → Logo navigation
+3. **Admin Access**: Login → Access admin features → Manage data
+
+### Component Interactions
+1. **FilterBar ↔ FilterContext**: State updates, loading states
+2. **HeaderNav ↔ AdminContext**: Role-based visibility
+3. **ExportModal ↔ AdminContext**: Feature access control
+4. **HelpPage ↔ Routing**: Navigation and page state
+
+### Error Handling
+1. **Empty States**: Handle missing data gracefully
+2. **Loading States**: Show appropriate loading indicators
+3. **Access Control**: Hide features based on user permissions
+
+## 🚨 Common Issues
+
+### Mock Configuration
+- Ensure all context hooks are properly mocked
+- Verify routing mocks return expected values
+- Check that component props match expected interfaces
+
+### Async Operations
+- Use `await userEvent.setup()` for user interactions
+- Wait for state updates with `waitFor`
+- Handle async context changes properly
+
+### Component Rendering
+- Wrap components with necessary providers
+- Mock external dependencies (JSZip, etc.)
+- Ensure test environment supports all required APIs
+
+## 🔍 Debugging Tips
+
+1. **Check Mock Returns**: Verify mocked functions return expected values
+2. **Component Props**: Ensure components receive required props
+3. **Provider Wrapping**: Check that all necessary context providers are included
+4. **Async Timing**: Use `waitFor` for state changes and async operations
+
+## 📈 Adding New Integration Tests
+
+To add a new integration test:
+
+1. **Identify Integration Points**: Determine which components interact
+2. **Choose Test Scope**: Decide on the level of integration to test
+3. **Mock Dependencies**: Mock external services and context hooks
+4. **Test User Flows**: Focus on realistic user interactions
+5. **Verify State Changes**: Check that state flows correctly between components
+
+## 🎯 Best Practices
+
+- **Test Real Interactions**: Focus on actual user workflows
+- **Minimize Mocking**: Only mock what's necessary for isolation
+- **Verify Integration**: Ensure components actually work together
+- **Test Edge Cases**: Include error states and boundary conditions
+- **Keep Tests Focused**: Each test should verify one integration aspect
+
+Integration tests ensure that your components work together as expected, providing confidence that the application functions correctly as a whole system.

+## Test Categories
+
+### Component Tests
+- **HeaderNav.test.tsx**: Tests navigation rendering, logo display, and button presence
+- **FilterBar.test.tsx**: Tests filter controls, input rendering, and loading states
+- **ExportModal.test.tsx**: Tests export modal functionality, bulk/single modes, and user interactions
+
+### Context Tests

+
+### Page Tests
+- **HelpPage.test.tsx**: Tests help page content, sections, and action buttons
+
+## Running Unit Tests
+
+```bash
+# Run all unit tests
+npm run test:unit
+
+# Run unit tests in watch mode
+npm run test:unit:watch
+
+# Run unit tests with coverage
+npm run test:unit:coverage
+```
+
+## Test Patterns
+
+### Component Testing
+```typescript
+import { render, screen } from '@testing-library/react'
+import { describe, it, expect, vi } from 'vitest'
+import ComponentName from '../../components/ComponentName'
+
+describe('ComponentName', () => {
+  it('renders without crashing', () => {
+    render(<ComponentName />)
+    expect(screen.getByText('Expected Text')).toBeInTheDocument()
+  })
+})
+```
+
+### Context Testing
+```typescript
+import { render, screen, fireEvent } from '@testing-library/react'
+import { describe, it, expect, vi } from 'vitest'
+import { ContextProvider } from '../../contexts/ContextName'
+import { useContextName } from '../../hooks/useContextName'
+
+// Test component to access context
+const TestComponent = () => {
+  const context = useContextName()
+  return <div data-testid="context-value">{context.value}</div>
+}
+```
+
+### Mocking
+```typescript
+// Mock external dependencies
+vi.mock('react-router-dom', () => ({
+  useNavigate: () => vi.fn(),
+  useLocation: () => ({ pathname: '/' }),
+}))
+
+// Mock hooks
+vi.mock('../../hooks/useHookName', () => ({
+  useHookName: () => ({
+    value: 'test',
+    setValue: vi.fn(),
+  }),
+}))
+```
+
+## Best Practices
+
+1. **Test individual components in isolation**
+2. **Mock external dependencies**
+3. **Test user interactions and state changes**
+4. **Use descriptive test names**
+5. **Keep tests focused and simple**
+6. **Test both success and error cases**
+
+## Coverage Goals
+
+- **Components**: 90%+ coverage
+- **Contexts**: 95%+ coverage  
+- **Pages**: 85%+ coverage
+- **Overall**: 90%+ coverage
