## 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. ✅ Check screenshot in test-results/
2. ✅ Watch video of test execution
3. ✅ Review trace file in Playwright inspector
4. ✅ Check console logs and errors
5. ✅ Verify element selectors are correct
6. ✅ Check for race conditions (use proper waits)
7. ✅ Verify viewport/device configuration
8. ✅ Check network conditions
9. ✅ Review recent code changes
10. ✅ Run test in isolation to confirm
## Getting Help
### Run with verbose logging
```bash
DEBUG=pw:api npx playwright test
```
