+# End-to-End Testing with Playwright
+
+This guide explains how to set up and run end-to-end tests for the ArkEnv website using Playwright.
+
+## Setup
+
+The E2E testing setup includes:
+
+1. **Playwright Configuration** (`playwright.config.ts`) - Configures test execution across multiple browsers
+2. **Test Scripts** (package.json) - Convenient commands for running tests
+3. **Test Files** (`e2e/*.spec.ts`) - Actual test implementations
+
+## Test Files
+
+### Homepage Tests (`e2e/homepage.spec.ts`)
+- Tests main page loading and content
+- Verifies navigation links work correctly
+- Checks responsive design
+- Validates external links
+
+### Documentation Tests (`e2e/documentation.spec.ts`)
+- Tests documentation page navigation
+- Verifies sidebar functionality
+- Checks search functionality if present
+- Tests responsive design for docs
+
+### Global Tests (`e2e/global.spec.ts`)
+- Tests global features like meta tags
+- Checks 404 error handling
+- Tests theme toggle functionality
+- Validates accessibility features
+- Tests JavaScript error handling
+- Validates banner functionality
+
+## Running Tests
+
+```bash
+# Install Playwright browsers (one-time setup)
+pnpm e2e:install
+
+# Run all E2E tests
+pnpm e2e
+
+# Run tests with browser UI visible
+pnpm e2e:headed
+
+# Run tests with Playwright UI mode
+pnpm e2e:ui
+```
+
+## Configuration
+
+The Playwright configuration is set up to:
+
+- Run tests across Chromium, Firefox, and WebKit browsers
+- Start the development server automatically before tests
+- Capture traces on test failures for debugging
+- Use parallel execution for faster test runs
+- Provide HTML reports for test results
+
+## Test Structure
+
+Each test file follows this pattern:
+
+1. **Import** necessary Playwright functions
+2. **Describe** test groups with `test.describe()`
+3. **Write** individual tests with `test()`
+4. **Use** page object patterns for better maintainability
+
+## Best Practices
+
+1. **Use semantic selectors** - Prefer `getByRole()`, `getByText()` over CSS selectors
+2. **Test user flows** - Focus on what users actually do
+3. **Keep tests focused** - Each test should verify one specific behavior
+4. **Use proper waits** - Wait for elements to be visible/loaded before assertions
+5. **Test responsive design** - Verify layout works on different screen sizes
+
+## CI Integration
+
+The E2E tests are designed to run in CI environments:
+
+- Tests run in headless mode by default
+- Retries are configured for CI environments
+- HTML reports are generated for debugging failures
+- Tests can be run in parallel for faster execution
+
+## Troubleshooting
+
+If tests fail:
+
+1. Check the HTML report generated after test runs
+2. Use `pnpm e2e:headed` to see tests run in browser
+3. Check that the development server is running correctly
+4. Verify environment variables are set properly
+
+## Environment Variables
+
+Tests may require these environment variables:
+
+- `NEXT_PUBLIC_GITHUB_URL` - GitHub repository URL
+- `NEXT_PUBLIC_SENTRY_DSN` - Sentry configuration (optional)
+
+## Future Enhancements
+
+Potential improvements to the E2E testing setup:
+
+1. **Visual regression testing** - Compare screenshots across test runs
+2. **API testing** - Test search API endpoints
+3. **Performance testing** - Measure page load times
+4. **Accessibility testing** - Automated a11y checks
+5. **Mobile testing** - Test on mobile device emulations
