# Playwright Testing

A skill that uses the browsing-with-playwright skill to visually test the portfolio website, take screenshots, check responsive design, and verify UI across different devices and viewports.

## Trigger Phrases

This skill activates when the user wants to test the website visually:
- "test the website"
- "take screenshots"
- "check responsive design"
- "test on mobile/desktop"
- "test responsive layout"
- "visual regression test"
- "check UI on different devices"

## Instructions

When this skill is invoked, use the browsing-with-playwright skill to perform visual testing:

### Step 1: Determine Test Scope

Ask the user (if not already specified):

1. **URL to test**: Local file path (file:///...) or deployed URL
2. **Test type**:
   - Full site test (all pages/sections)

   - Responsive design test
   - Screenshot capture only
3. **Viewports**: Which devices to test (mobile, tablet, desktop, all)
4. **What to verify**: Layout, colors, typography, spacing, dark mode, etc.

### Step 2: Set Up Common Viewports

Use these standard viewport sizes for responsive testing:

#### Mobile Devices
- **iPhone SE**: 375x667 (small mobile)

## Common Visual Issues to Check For

### Layout Issues
- **Horizontal scrolling**: Content wider than viewport
- **Overlapping elements**: Elements positioned on top of each other
- **Broken grid**: Grid items not aligning properly
- **Incorrect spacing**: Inconsistent margins/padding
- **Text overflow**: Text extending beyond container
- **Missing breakpoints**: Layout not adapting at viewport changes

### Responsive Issues
- **No mobile menu**: Desktop nav on mobile viewport
- **Small touch targets**: Buttons/links too small on mobile
- **Text too small**: Font size not readable on mobile
- **Images not scaling**: Fixed-width images breaking layout
- **Horizontal scroll**: Content not fitting mobile viewport
- **Incorrect orientation**: Layout breaking in landscape mode

### Color & Theme Issues
- **Low contrast**: Text hard to read on background
- **Wrong colors**: Not using design system colors
- **Dark mode not working**: Elements not adapting to dark theme
- **Missing hover states**: No visual feedback on hover
- **Invisible elements**: Elements same color as background

### Typography Issues
- **Text cut-off**: Headings or content truncated
- **Wrong font sizes**: Not following typography scale
- **Poor line height**: Text cramped or too spaced
- **Alignment issues**: Text not aligned properly
- **Font not loading**: Fallback font being used

### Component Issues
- **Broken buttons**: Buttons not displaying correctly
- **Card layout issues**: Cards misaligned or wrong size
- **Form problems**: Inputs not aligned or styled properly
- **Navigation issues**: Nav not working on mobile
- **Image problems**: Images not loading or broken aspect ratio

## Best Practices for Visual Testing

### Testing Strategy
1. **Test early and often**: Don't wait until the end
2. **Test on real devices**: Emulation is good, but real devices are better
3. **Test both themes**: Always check light and dark modes
4. **Test all breakpoints**: Mobile, tablet, desktop, and in-between sizes
5. **Test interactions**: Hover, focus, active, disabled states
6. **Test with real content**: Use realistic text lengths and image sizes

### Screenshot Best Practices
1. **Consistent naming**: Use clear, descriptive filenames
2. **Organize by viewport**: Group screenshots by device size
3. **Include both themes**: Take screenshots in light and dark modes
4. **Capture interactions**: Screenshot hover/focus states
5. **Full page vs component**: Take both full page and component shots
6. **Annotate issues**: Mark up screenshots to highlight problems

### Using browsing-with-playwright
1. **Start simple**: Begin with basic navigation and screenshots
2. **Be specific**: Give clear instructions (viewport size, URL, action)
3. **Wait for load**: Ensure page fully loads before screenshots
4. **Test interactions**: Click, hover, scroll to test UI
5. **Check console**: Look for JavaScript errors
6. **Verify elements**: Check that elements exist before interacting

## Viewport Breakpoint Strategy

Based on the portfolio project's responsive design:

### CSS Breakpoints
```css
/* Mobile: default styles (< 768px) */

/* Tablet */
@media (min-width: 768px) {
  /* Tablet styles */
}

/* Desktop */
@media (min-width: 1024px) {
  /* Desktop styles */
}

/* Large Desktop */
@media (min-width: 1440px) {
  /* Large desktop styles */
}
```

### Test at These Specific Widths
- **320px**: Minimum mobile width (iPhone SE)
- **375px**: Standard mobile (iPhone 12/13)
- **767px**: Just below tablet breakpoint
- **768px**: Tablet breakpoint start
- **1023px**: Just below desktop breakpoint
- **1024px**: Desktop breakpoint start
- **1439px**: Just below large desktop breakpoint
- **1440px**: Large desktop breakpoint start
- **1920px**: Standard desktop

## Notes

- Always use the `browsing-with-playwright` skill for actual browser automation
- Don't suggest installing Playwright MCP - use the skill instead
- Test local files with `file:///` protocol
- Test deployed sites with `https://` protocol
- Visual testing catches issues automated tests miss
- Real device testing is important for touch interactions
- Screenshots are valuable for visual regression testing
- Keep screenshots organized for easy comparison
- Document any visual inconsistencies found
- Prioritize fixes based on severity and viewport usage
- Mobile-first approach means mobile testing is critical
