+## Testing
+
+QueryWeaver includes a comprehensive test suite with both unit and End-to-End (E2E) tests.
+
+### Quick Start
+
+```bash
+# Set up test environment
+./setup_e2e_tests.sh
+
+# Run all tests
+make test
+
+# Run only unit tests
+make test-unit
+
+# Run E2E tests (headless)
+make test-e2e
+
+# Run E2E tests with visible browser
+make test-e2e-headed
+```
+
+### Test Types
+
+- **Unit Tests**: Test individual components and functions
+- **E2E Tests**: Test complete user workflows using Playwright
+  - Basic functionality (page loading, UI structure)
+  - Authentication flows (OAuth integration)
+  - File upload and processing
+  - Chat interface and query handling
+  - API endpoint testing
+
+See [tests/e2e/README.md](tests/e2e/README.md) for detailed E2E testing documentation.
+
+### CI/CD

+# E2E Testing with Playwright
+
+This directory contains End-to-End (E2E) tests for QueryWeaver using Playwright. These tests verify the application's functionality from a user's perspective, testing the complete user workflows.
+
+## Overview
+
+The E2E test suite covers:
+
+- **Basic Functionality**: Page loading, UI structure, responsive design
+- **Authentication Flow**: Login/logout processes (OAuth integration)
+- **File Upload**: CSV, JSON file processing and data loading
+- **Chat Interface**: Query submission and response handling
+- **API Endpoints**: Direct API testing and error handling
+
+## Test Structure
+
+```
+tests/e2e/
+├── pages/              # Page Object Model classes
+│   ├── base_page.py   # Base page with common functionality
+│   └── home_page.py   # Home/chat page interactions
+├── fixtures/          # Test data and utilities
+│   └── test_data.py   # Sample data generators
+├── test_basic_functionality.py  # Core app functionality tests
+├── test_file_upload.py          # File upload feature tests
+├── test_chat_functionality.py   # Chat interface tests
+└── test_api_endpoints.py        # Direct API endpoint tests
+```
+
+## Quick Start
+
+### Prerequisites
+
+1. Python 3.12+
+2. pipenv
+3. Docker (for FalkorDB, optional for basic tests)
+
+### Setup
+
+Run the setup script:
+```bash
+./setup_e2e_tests.sh
+```
+
+Or manually:
+```bash
+# Install dependencies
+pipenv sync --dev
+
+# Install Playwright browsers
+pipenv run playwright install chromium
+
+# Copy environment file
+cp .env.example .env
+# Edit .env with your settings
+```
+
+### Running Tests
+
+```bash
+# Run all tests
+make test
+
+# Run only E2E tests (headless)
+make test-e2e
+
+# Run E2E tests with visible browser
+make test-e2e-headed
+
+# Run specific test file
+pipenv run pytest tests/e2e/test_basic_functionality.py -v
+
+# Run with debugging
+make test-e2e-debug
+```
+
+## Test Categories
+
+### ✅ Basic Functionality Tests
+These tests run without authentication and verify:
+- Application loads correctly
+- UI structure is present
+- Responsive design works
+- Error handling for invalid routes
+
+### ⏸️ Authentication Tests
+Currently skipped (require OAuth setup):
+- Google OAuth login flow
+- GitHub OAuth login flow
+- Session management
+- Authenticated user interface
+
+### ⏸️ File Upload Tests
+Currently skipped (require authentication):
+- CSV file upload and processing
+- JSON file upload and processing
+- Invalid file handling
+- File processing feedback
+
+### ⏸️ Chat Functionality Tests
+Currently skipped (require authentication + data):
+- Query submission
+- Response streaming
+- Multiple query handling
+- Graph selection
+
+### ✅ API Endpoint Tests
+These test the API directly:
+- Health checks
+- Authentication-protected endpoints
+- Static file serving
+- Error responses
+
+## Configuration
+
+### Environment Variables
+
+Key environment variables for testing:
+```bash
+# Required for Flask
+FLASK_SECRET_KEY=your-secret-key
+FLASK_DEBUG=False
+
+# Database connection (optional for basic tests)
+FALKORDB_HOST=localhost
+FALKORDB_PORT=6379
+
+# OAuth (required for full E2E tests)
+GOOGLE_CLIENT_ID=your-google-client-id
+GOOGLE_CLIENT_SECRET=your-google-client-secret
+GITHUB_CLIENT_ID=your-github-client-id
+GITHUB_CLIENT_SECRET=your-github-client-secret
+```
+
+### Test Markers
+
+Tests use pytest markers for organization:
+- `@pytest.mark.skip()`: Tests requiring setup
+- Can add custom markers like `@pytest.mark.auth` for authenticated tests
+
+## CI/CD Integration
+
+### GitHub Actions
+
+The E2E tests run automatically in CI via `.github/workflows/tests.yml`:
+
+- **Unit Tests**: Run first to catch basic issues
+- **E2E Tests**: Run after unit tests pass
+- **Services**: Automatically starts FalkorDB container
+- **Artifacts**: Saves screenshots and reports on failure
+
+### Running Locally with Docker
+
+Start FalkorDB for full testing:
+```bash
+make docker-falkordb
+make test-e2e
+make docker-stop
+```
+
+## Debugging Tests
+
+### Screenshots and Videos
+
+Failed tests automatically capture:
+- Screenshots at failure point
+- Video recordings (in CI)
+- Browser console logs
+
+### Running in Debug Mode
+
+```bash
+# Run with visible browser and slow motion
+make test-e2e-debug
+
+# Run specific test with debugging
+pipenv run pytest tests/e2e/test_basic_functionality.py::TestBasicFunctionality::test_home_page_loads -v --headed
+```
+
+### Common Issues
+
+1. **Port Conflicts**: Ensure port 5000 is available
+2. **Browser Installation**: Run `pipenv run playwright install chromium`
+3. **FalkorDB Connection**: Check if FalkorDB is running on port 6379
+4. **Environment Variables**: Verify `.env` file is configured
+
+## Extending Tests
+
+### Adding New Tests
+
+1. **Create Test File**: Follow naming convention `test_*.py`
+2. **Use Page Objects**: Extend existing page objects or create new ones
+3. **Add Test Data**: Use fixtures in `tests/e2e/fixtures/`
+4. **Mark Appropriately**: Use `@pytest.mark.skip()` for tests requiring setup
+
+### Page Object Example
+
+```python
+from tests.e2e.pages.base_page import BasePage
+
+class NewPage(BasePage):
+    BUTTON_SELECTOR = "#my-button"
+
+    def click_button(self):
+        self.page.click(self.BUTTON_SELECTOR)
+```
+
+### Test Example
+
+```python
+def test_new_functionality(page_with_base_url):
+    page_obj = NewPage(page_with_base_url)
+    page_obj.navigate_to("/new-route")
+    page_obj.click_button()
+    assert page_obj.get_page_title() == "Expected Title"
+```
+
+## Future Improvements
+
+- [ ] Add authentication setup for full E2E testing
+- [ ] Add performance testing with Playwright
+- [ ] Add visual regression testing
+- [ ] Add mobile device testing
+- [ ] Add accessibility testing
+- [ ] Add database state verification
+- [ ] Add test data management utilities
+
+## Contributing
+
+When adding new tests:
+
+1. Follow the existing Page Object Model pattern
+2. Add appropriate test markers
+3. Update this README if adding new test categories
+4. Ensure tests can run in CI environment
+5. Add proper cleanup for any test data created
