Summary

Triggered by: @pelikhan
Workflow Run: https://github.com/githubnext/gh-aw/actions/runs/20407814676
Date: 2025-12-21
Status: ⚠️ Unable to complete - Technical limitation

Build Status

✅ Documentation Build: Successfully completed

• Generated 121 lab workflows
• Built 68 pages with Mermaid diagrams
• Created search index with Pagefind
• All internal links validated

✅ Preview Server: Successfully started

• Running at: `(redacted)
• Server confirmed responsive via curl
• Build artifacts ready for testing

Testing Plan

The comprehensive multi-device testing plan included:

Mobile Devices

• iPhone 12 (390×844)
• iPhone 12 Pro Max (428×926)
• Pixel 5 (393×851)
• Galaxy S21 (360×800)

Tablet Devices

• iPad (768×1024)
• iPad Pro 11 (834×1194)
• iPad Pro 12.9 (1024×1366)

Desktop Devices

• HD (1366×768)
• FHD (1920×1080)
• 4K (2560×1440)

Test Coverage

For each device, the plan included:

• ✅ Layout responsiveness testing
• ✅ Navigation functionality
• ✅ Search feature testing
• ✅ Interactive element verification
• ✅ Accessibility audits
• ✅ Visual rendering checks
• ✅ Screenshot capture

Technical Limitation

❌ Playwright Network Isolation Issue

The Playwright MCP server cannot connect to localhost services:

Error: page.goto: net::ERR_CONNECTION_REFUSED at (redacted)

Root Cause: The Playwright browser instance runs in a sandboxed environment that blocks access to localhost network services, even though:

• The preview server is confirmed running (PID verified)
• Server responds successfully to curl requests
• Server is bound to 127.0.0.1:4321

Attempted Solutions:

1. ✅ Server restart with explicit host binding
2. ✅ Alternative localhost addresses (localhost, 127.0.0.1)
3. ✅ Playwright viewport configuration
4. ✅ Direct browser navigation and code execution
5. ❌ All attempts resulted in ERR_CONNECTION_REFUSED

Recommendations

Option 1: Deploy to Test Environment (Recommended)

Deploy the documentation to a publicly accessible URL (e.g., GitHub Pages preview, Netlify deploy preview) where Playwright can access it without localhost restrictions.

Option 2: Alternative Testing Tools

Consider using testing tools that support localhost access:

• Puppeteer with custom launch options
• Selenium WebDriver
• Cypress (if it supports the testing requirements)

Option 3: Docker Network Bridge

Configure Playwright to run in a Docker container with proper network bridge configuration to access host services.

Option 4: Manual Testing

Perform manual testing across devices using:

• Browser DevTools device emulation
• Real device testing via BrowserStack/Sauce Labs
• Responsive design testing tools

Files Generated

The documentation build generated:

• dist/ - Static site ready for deployment (69 pages)
• dist/pagefind/ - Search index
• public/slides/ - Presentation slides
• Multiple Mermaid diagrams rendered

Next Steps

1. Deploy preview: Set up a temporary deployment for testing
2. Rerun workflow: Execute multi-device tests against deployed URL
3. Document findings: Create comprehensive test report with screenshots
4. Fix issues: Address any responsive design or accessibility issues found

Technical Details

Environment:

• Node.js build: ✅ Successful
• Astro v5.15.9: ✅ Running
• Preview server: ✅ Active (PID: 8402)
• Playwright: ⚠️ Network isolation

Build Output:

• Total pages: 68
• Indexed words: 5,167
• Build time: 18.84s
• Link validation: ✅ All valid

Would you like me to:

1. Set up a GitHub Pages preview deployment?
2. Generate a manual testing checklist?
3. Explore alternative testing configurations?

Q Investigation Complete ✅

I've analyzed the Playwright configuration issue reported in this issue and created a comprehensive fix.

Problem Identified

Root Cause: Playwright MCP runs in a Docker container with isolated networking. When workflows start local preview servers on localhost:4321, the Playwright container cannot access them because from inside Docker, localhost refers to the container itself, not the host machine.

Solution Implemented

Created PR with fixes for 4 affected workflows:

1. Multi-Device Docs Tester - Updated to perform static analysis with deployment-based testing recommendations
2. Documentation Noob Tester - Fixed to use host.docker.internal with proper server binding
3. Slide Deck Maintainer - Fixed to use host.docker.internal for layout detection
4. Unbloat Docs - Fixed server binding and Playwright URL configuration

New Documentation

Created comprehensive guide at .github/workflows/shared/playwright-localhost-limitation.md covering:

• Why the issue occurs (Docker network isolation)
• Three solution approaches (deploy to URL, use host.docker.internal, or static analysis)
• Complete working examples for each approach
• Common pitfalls and best practices

Key Changes

For workflows needing Playwright:

# Bind server to all interfaces (not just localhost)
npm run preview -- --host 0.0.0.0

# Access from Playwright using special Docker hostname
await page.goto('(redacted)

For workflows where testing isn't critical:

• Document the limitation
• Recommend deployment-based testing
• Provide static analysis alternatives

This fix enables proper Playwright functionality while maintaining security and providing clear guidance for future workflows.
