+ - Use env(safe-area-inset-*)
+
+5. **Verify Touch Targets**
+ - 44px minimum (WCAG)
+ - 8px spacing
+ - No overlaps
+
+6. **Test Real Scenarios**
+ - Interrupted by call/SMS
+ - App backgrounding
+ - Network switching

+# Manual test on Android
+# (Or use emulator)
+```
+
+### Day 5: Process Implementation (30 min)
+- Add QA checklist to your process
+- Train team on Android testing
+- Setup pre-release verification
+
+## ๐ Key Concepts
+
+### Consistency, Not Replication
+**Same features, adapted layout:**
+- Desktop: Horizontal nav
+- Android: Vertical menu or hamburger
+- **Result:** Same routes, same functionality
+
+### Touch-First, Not Afterthought
+**Requirements:**
+- 44px ร 44px minimum buttons
+- 8px spacing between targets
+- Safe areas respected
+- Keyboard-friendly
+
+### Performance Targets
+- Desktop: < 3 seconds
+- Android: < 5 seconds
+- Both: < 100ms interaction response
+
+### Documentation Parity
+- All docs mention Android
+- Mobile-specific instructions
+- Mobile screenshots
+- Mobile troubleshooting

+
+## Debugging Android Issues
+
+### No Horizontal Scroll Issue
+```typescript
+const overflow = await page.evaluate(() =>
+ Math.max(document.documentElement.scrollWidth - window.innerWidth, 0)
+);
+console.log("Horizontal overflow:", overflow);
+```
+
+### Button Not Tappable
+```typescript
+const box = await button.boundingBox();
+console.log("Button size:", box.width, "x", box.height);
+// Should be >= 44x44
+```
+
+### Text Cut Off
+```typescript
+const overflow = await element.evaluate(el =>
+ el.scrollWidth > el.clientWidth || el.scrollHeight > el.clientHeight
+);
+console.log("Text overflow:", overflow);
+```
+
+### Keyboard Issues
+```typescript
+const input = page.locator("input");
+await input.click();
+console.log("Input type:", await input.getAttribute("type"));
+// Should trigger appropriate keyboard
+```
+
+## Integration with Documentation
+
+All documentation in `/docs` folder should reflect Android UI consistency:
+
+1. **Screenshots** - Include Android versions
+2. **Instructions** - Use "tap" instead of "click"
+3. **Features** - Clarify mobile availability
+4. **Setup** - Include mobile setup steps
+5. **Troubleshooting** - Add mobile issues
+
+## Summary
+
+The UI **MUST** work identically on Android as on desktop with these adaptations:
+- Navigation reorganized but all routes accessible
+- Forms and inputs adapted for touch
+- Layout optimized for 393px width
+- Typography sized for readability
+- Touch targets 44px minimum
+- No horizontal scrolling
+- Performance optimized for mobile networks
+
+All documentation should reflect Android as a primary platform, not secondary.

+# Playwright Test Debugging Guide
+
+## Quick Debug Commands
+
+### View test report after running
+```bash
+npx playwright show-report
+```
+
+### Run tests with browser visible (headed mode)
+```bash
+npx playwright test --headed
+```
+
+### Step through tests interactively
+```bash
+npx playwright test --debug
+```
+
+### View test execution with timeline
+```bash
+npx playwright test --headed --workers=1
+```
+
+### See trace of test execution
+```bash
+npx playwright test --trace on
+```
+
+### Run single test by name pattern
+```bash
+npx playwright test -g "button focus state"
+```
+
+### Run specific test file
+```bash
+npx playwright test tests/e2e/visual-regression.spec.ts
+```
+
+### Run specific test group
+```bash
+npx playwright test -g "Mobile Touch"
+```
+
+### Update snapshots (for visual regression)
+```bash
+npx playwright test --update-snapshots
+```
+
+## Debugging Failed Tests
+
+### 1. Screenshot Inspection
+Failed tests automatically capture screenshots in:
+```
+test-results/[test-name]/test-failed-1.png
+```
+
+### 2. Video Playback
+Videos of failed tests are saved in:
+```
+test-results/[test-name]/video.webm
+```
+
+### 3. Trace Files
+Debug traces are at:
+```
+test-results/[test-name]/trace.zip
+```
+
+Open with: `npx playwright show-trace test-results/[test-name]/trace.zip`
+
+### 4. Console Output
+View full output with:
+```bash
+npx playwright test --reporter=list
+```
+
+## Common Issues and Solutions
+
+### Issue: Tests timeout on CI but work locally
+**Solution**: Check network speed
+```bash
+# Run with slower network simulation
+npx playwright test --headed --workers=1
+```
+
+### Issue: Intermittent test failures
+**Solution**: Add more wait conditions
+```typescript
+await page.waitForLoadState('networkidle')
+await page.waitForTimeout(500)
+```
+
+### Issue: Visual regression snapshot mismatch
+**Solution**: Update baseline if changes are intentional
+```bash
+npx playwright test --update-snapshots
+```
+
+### Issue: Touch/mobile tests fail on desktop
+**Solution**: Tests should skip appropriately. Check:
+```typescript
+test.skip(!testInfo.project.name.includes("mobile"), "mobile-only")
+```
+
+### Issue: Memory leak detection
+**Solution**: Run with memory profiling
+```bash
+npx playwright test --headed --workers=1
+```
+
+## Test Modification Tips
+
+### Add debug logging to test
+```typescript
+test("my test", async ({ page }) => {
+ console.log("Current URL:", page.url());
+ console.log("Page title:", await page.title());
+
+ // Add pause for inspection
+ await page.pause(); // Browser will wait for you to continue
+
+ // Your test...
+});
+```
+
+### Inspect element in debug mode
+```typescript
+test("inspect element", async ({ page }) => {
+ await page.goto("/");
+ await page.pause();
+
+ // Browser devtools will open, inspect the element
+ const element = page.locator("button").first();
+ console.log(await element.boundingBox());
+});
+```
+
+### Check computed styles
+```typescript
+const styles = await element.evaluate(el => {
+ const computed = window.getComputedStyle(el);
+ return {
+ color: computed.color,
+ background: computed.backgroundColor,
+ fontSize: computed.fontSize,
+ };
+});
+console.log("Computed styles:", styles);
+```
+
+### Network interception for debugging
+```typescript
+// See all network requests
+page.on("request", request => {
+ console.log("Request:", request.url(), request.method());
+});
+
+page.on("response", response => {
+ console.log("Response:", response.url(), response.status());
+});
+```
+
+## Performance Profiling
+
+### Check page metrics
+```typescript
+const metrics = await page.metrics();
+console.log(`Memory: ${metrics.JSHeapUsedSize / 1048576 | 0} MB`);
+console.log(`Layout count: ${metrics.LayoutCount}`);
+console.log(`Recalc style count: ${metrics.RecalcStyleCount}`);
+```
+
+### Measure navigation timing
+```typescript
+const timing = await page.evaluate(() => {
+ const nav = performance.getEntriesByType("navigation")[0];
+ return {
+ loadTime: nav.loadEventEnd - nav.loadEventStart,
+ domReady: nav.domContentLoadedEventEnd - nav.loadEventStart,
+ transfer: nav.responseEnd - nav.requestStart,
+ };
+});
+console.log("Timing:", timing);
+```
+
+## Viewport and Device Testing
+
+### Test specific resolution
+```bash
+# Run only on desktop
+npx playwright test --project=chromium-desktop
+
+# Run only on mobile
+npx playwright test --project=chromium-mobile
+```
+
+### Test custom viewport
+```typescript
+const context = await browser.newContext({
+ viewport: { width: 1920, height: 1080 },
+});
+```
+
+## Accessibility Debugging
+
+### Check ARIA attributes
+```typescript
+const role = await element.getAttribute("role");
+const label = await element.getAttribute("aria-label");
+const expanded = await element.getAttribute("aria-expanded");
+
+console.log({ role, label, expanded });
+```
+
+### Verify keyboard navigation
+```typescript
+// Tab through elements
+for (let i = 0; i < 10; i++) {
+ await page.keyboard.press("Tab");
+ const focused = await page.evaluate(() => document.activeElement?.tagName);
+ console.log(`Tab ${i}:`, focused);
+}
+```
+
+## Test Report Customization
+
+### Generate detailed JSON report
+```bash
+npx playwright test --reporter=json > report.json
+```
+
+### Generate HTML report
+```bash
+npx playwright test --reporter=html
+```
+
+### Custom report format
+```bash
+npx playwright test --reporter=junit
+```
+
+## Debugging Tips by Test Type
+
+### Visual Regression Tests
+1. Save baseline images locally
+2. Compare pixel-by-pixel differences
+3. Check for animation timing issues
+4. Verify screenshot size matches viewport
+
+### Functionality Tests
+1. Check for console errors with `page.on("console")`
+2. Monitor network requests for failures
+3. Verify state changes after interactions
+4. Check DOM mutations after actions
+
+### Mobile Tests
+1. Verify touch events register properly
+2. Check viewport dimensions in browser
+3. Test safe area and notch handling
+4. Verify input type matches mobile keyboard
+
+### Performance Tests
+1. Check metrics before and after actions
+2. Monitor heap size growth
+3. Track layout recalculation count
+4. Measure script execution time
+
+## Useful Playwright Methods for Debugging
+
+```typescript
+// Get element information
+await element.boundingBox(); // Position and size
+await element.getAttribute("class"); // Class names
+await element.isVisible(); // Visibility
+await element.isEnabled(); // Enabled state
+
+// Page inspection
+await page.content(); // Full HTML
+await page.textContent(); // All text
+await page.title(); // Page title
+await page.url(); // Current URL
+
+// Console/error monitoring
+page.on("console", msg => console.log(msg));
+page.on("pageerror", err => console.log(err));
+
+// Performance data
+await page.metrics(); // Performance metrics
+```
+
+## Test Failure Checklist
+
+When a test fails:
+1. โ
Check screenshot in test-results/
+2. โ
Watch video of test execution
+3. โ
Review trace file in Playwright inspector
+4. โ
Check console logs and errors
+5. โ
Verify element selectors are correct
+6. โ
Check for race conditions (use proper waits)
+7. โ
Verify viewport/device configuration
+8. โ
Check network conditions
+9. โ
