2. Test Infrastructure Restructuring (60% Complete)

Objective: Align core package tests with the successful UI test pattern that uses file:// URLs and fixture HTML files. Completed:

✅ Restructured test-utils.mjs to use file:// URLs (matches UI pattern)
✅ Created test fixture HTML files:

- tests/fixtures/basic-pan-bus.html - PAN Bus test fixture - tests/fixtures/pan-client-test.html - PAN Client test fixture

✅ Rewrote pan-bus.test.mjs following UI test pattern:

- Manual browser lifecycle management (beforeAll/afterAll) - Navigate to fixture files instead of setContent() - Import chromium directly

✅ Updated playwright.config.js (removed web server requirement)
✅ Created 8 comprehensive tests for pan-bus:

- Component registration - Configuration via attributes - Message publishing & delivery - Wildcard subscriptions - Topic validation Blocked:

⏳ Module loading not working in file:// context
⏳ Tests timeout waiting for modules to load
⏳ Page crashes before test execution

Root Cause: ES module imports may have Cross-Origin restrictions in file:// URLs. The UI tests work because they use a different import pattern or have a web server running.

🟡 Remaining Work

1. Fix Test Module Loading (CRITICAL)

Problem: Tests cannot execute because ES modules aren't loading in the file:// URL context. Possible Solutions: Option A: Use Playwright's built-in web server (recommended)

// playwright.config.js
webServer: {
  command: 'python3 -m http.server 8080 --directory .',
  url: 'http://localhost:8080',
  reuseExistingServer: true,
  timeout: 120000,
}

// test-utils.mjs
export function fileUrl(relativePath) {
  return `http://localhost:8080/${relativePath}`;
}

Option B: Use data: URLs for inline modules (complex) Option C: Bundle modules for testing (requires build step) Option D: Check UI test setup more carefully

The UI tests claim to use file:// URLs successfully
May have different project structure or module resolution
Should investigate actual UI test execution

Recommendation: Go with Option A - it's the most straightforward and matches Playwright best practices.

2. Complete Test Suite

Once module loading is fixed:

✅ pan-bus.test.mjs (restructured, needs execution)
⏳ pan-client.test.mjs (needs restructuring)
⏳ pan.test.mjs (needs restructuring)
⏳ features.test.mjs (needs creation)
⏳ Integration tests (needs creation)

Estimated Effort: 2-4 hours once blocking issue resolved

3. API Stability Audit

Tasks:

[ ] Review all exported APIs in core package
[ ] Document stability guarantees
[ ] Create API compatibility tests
[ ] Freeze APIs for v1.x
[ ] Update SEMVER.md with specific API commitments

Estimated Effort: 4-6 hours

4. Integration Test Suite

Tasks:

[ ] Create end-to-end workflow tests
[ ] Test component interaction patterns
[ ] Test error recovery
[ ] Test performance under load
[ ] Test browser compatibility

Estimated Effort: 8-12 hours

5. CI/CD Integration

Tasks:

[ ] Set up GitHub Actions workflow
[ ] Configure cross-browser testing
[ ] Add coverage reporting
[ ] Set up automated deployment
[ ] Configure security scanning

Estimated Effort: 4-6 hours

Notes

What Went Well

Documentation was comprehensive and well-structured
Following UI test pattern was the right approach
Clear understanding of what's needed for production

Challenges

Module loading in file:// context is tricky
Test configuration more complex than expected
Need to better understand UI test setup

Lessons Learned

Start with working reference implementation (UI tests)
Test infrastructure first, then write tests
Module resolution differs between file:// and http:// contexts
