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

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

/* 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
