+npm run test:comprehensive
+
+# Run specific test suites against production
+npm run test:comprehensive-production
+npm run test:individual-pages  
+npm run test:cross-browser
+
+# Run all production tests together
+npm run test:production-all
+```
+
+### Focused Test Categories
+```bash
+# Test accessibility compliance
+npm run test:accessibility
+
+# Test responsive design
+npm run test:responsive
+
+# Test performance metrics
+npm run test:performance
+```
+
+### Local Development Tests
+```bash
+# Run tests against local development server
+npm run test:e2e
+
+# Run with browser visible (debugging)
+npm run test:e2e-headed
+
+# Interactive test runner
+npm run test:e2e-ui
+```
+
+### Real Network Tests
+```bash
+# Test with real Solana network data
+npm run test:realnet
+
+# Real network tests with browser visible
+npm run test:realnet-headed
+```
+
+## 🎛️ Configuration
+
+### Environment Variables
+```bash
+# Test against specific URL
+export PLAYWRIGHT_BASE_URL="https://svmseek.com"
+
+# Enable real network tests
+export REALNET_TESTS="true"
+
+# Set specific device for testing
+export DEVICE_NAME="iPhone 12"
+```
+
+### Test Configuration
+The tests are configured in `playwright.config.ts`:
+- **Production URL**: `https://svmseek.com` (configurable via env var)
+- **Timeout**: 30 seconds for production network calls
+- **Retries**: 2 retries on CI, 0 locally
+- **Browsers**: Chromium, Firefox, WebKit
+- **Devices**: Desktop, tablet, mobile variants
+
+## 📊 Test Reports
+
+### HTML Reports
+After running tests, view detailed HTML reports:
+```bash
+npx playwright show-report
+```
+
+### Screenshots
+All test failures and key interactions are automatically captured:
+- Saved to `/tmp/screenshots/`
+- Uploaded as GitHub Actions artifacts
+- Available in HTML reports
+
+### Performance Metrics
+Tests capture and validate:
+- Page load times (< 15 seconds on production)
+- DOM Content Loaded (< 10 seconds)
+- First Paint / First Contentful Paint
+- Memory usage patterns
+
+## 🔧 GitHub Actions Integration
+
+### Automated Testing
+The comprehensive test suite runs automatically on:
+- **Push to main/master**: Full test matrix
+- **Pull Requests**: Comprehensive validation
+- **Daily Schedule**: Production health checks
+- **Manual Trigger**: On-demand testing
+
+### Test Matrix
+```yaml
+Strategy:
+  Browser: [chromium, firefox, webkit]  
+  Shard: [1, 2, 3, 4]                  # Parallel execution
+  Device: [iPhone 12, Pixel 5, iPad Pro, etc.]
+```
+
+### Artifacts
+All test runs generate:
+- ✅ HTML test reports
+- ✅ Screenshot galleries  
+- ✅ Performance metrics
+- ✅ Error logs and debugging info
+- ✅ Consolidated test summaries
+
+## 🛡️ Quality Gates

+
+## 🐛 Debugging Failed Tests
+
+### Local Debugging
+```bash
+# Run specific test with browser visible
+npx playwright test e2e/comprehensive-production.spec.ts --headed --grep "wallet creation"
+
+# Debug mode with inspector
+npx playwright test --debug
+
+# Generate trace for analysis
+npx playwright test --trace on
+```
+
+### CI/CD Debugging
+1. **Download artifacts** from failed GitHub Actions run
+2. **View HTML reports** in browser
+3. **Examine screenshots** for visual issues
+4. **Check console logs** in test output
+5. **Analyze performance metrics** if available
+
