End-to-end manual test suite: full framework verification

[qantrepreneur]

Purpose

Permanent logbook for end-to-end framework verification. Pinned — never close.

How to use this issue

1. Testing round: Run all items top-to-bottom. Check off passes. On failure → create a bug issue with needs-triage label and link it inline with BLOCKED by #NNN.
2. After a fix lands: Comment noting which PR landed, which items to re-test, then reset those checkmarks and re-run.
3. Playground is editable: If a test needs a route/config that doesn't exist, create it in the playground. The playground exists to be tested.
4. Never close this issue. It's a living document.

Log

• Round 1 (2026-05-15): Items 1-10 tested on 138-entry-shim. Items 15, 32-37, 49-50 blocked by Bug: extractModule doesn't unwrap handler exports → all handler routes return 405 #157.
• Reset (2026-05-16): PR feat: standardize route modules to export default with RouteKind brand #162 merged (default export + RouteKind brand). All items invalidated.
• Round 2 (2026-05-16): Full re-test on main @ 4228a11. Created test routes for async loader, request params, dynamic routes, context, multi-method handler, meta pages, etc.

Dev server startup

• 1. pnpm dev starts without errors
• 2. Server responds on expected port
• 3. routes.gen.ts generated on startup with correct route map
• 4. framework.gen.d.ts generated with correct type declarations

Static page rendering

• 5. / — full HTML document: doctype, html, head, body all present
• 6. / — correct charset, viewport meta tags (note: charset + viewport duplicated — cosmetic)
• 7. / — page content renders inside template slots
• 8. / — view source shows server-rendered HTML (not empty div)
• 9. / — zero JS shipped (no script tags, no hydration markers)

Loader + data flow

• 10. /demo — loader executes, data appears in rendered HTML
• 11. Async loader — resolves before page renders (tested via /async-loader)
• 12. Loader receives request object (tested via /request-test?name=claude)
• 13. Loader receives params on dynamic route (tested via /blog/my-first-post)
• 14. Loader receives app context from createApp.context() (tested via /context-test)
• 15. Loader that throws — triggers error page, doesn't hang (tested via /throw-test → 500)

Slots + templates

• 16. /demo — all named slots render in correct template positions
• 17. Slot fallback content shows when slot not provided (tested via /partial-slots — main shows "No content provided.")
• 18. Invalid slot name — dev error with Levenshtein suggestion (tested via /typo-slot → 500 with "Did you mean headr?")
• 19. Multiple slots on same page all render
• 20. Template CSS/styles load correctly (N/A — no CSS in playground template, but mechanism works)

Hydration + interactivity

• 21. /demo Counter — SSR markup present before JS loads (button text "Count: 0" in server HTML)
• 22. Counter — JS hydrates, click increments value (browser-verified: Count increments on click)
• 23. Counter — only its slot has data-hydrate attribute (header/footer use data-slot, main uses data-hydrate)
• 24. Counter — only its slot has hydration script + JSON data block
• 25. Static slots on same page have zero JS (header/footer have data-slot, no hydration scripts)
• 26. Hydration doesn't cause content flash/mismatch (no React mismatch warnings in console)
• 27. Disable JS in browser — static content still readable (full HTML in server response)
• 28. Hydration boundary wraps interactive slot in <div data-hydrate="slotId">
• 29. Loader data present in <script type="application/json" data-hydrate-data="slotId"> tag
• 30. XSS protection — < in loader data escaped as < in hydration JSON (code-verified: escapeScriptContent in inject-hydration.ts)
• 31. Production asset paths — hydration <script type="module"> imports hashed /_client/assets/… URL (verified in prod build output)
• 32. Transitive interactivity — slot importing a component that uses useState is treated as interactive (demo/main → Counter → useState, manifest marks as true)
• 33. Purely static page — zero <script type="module"> hydration tags injected (verified on /)

Meta / head

• 34. Static meta — title and description render in <head> (tested via /meta-static)
• 35. Dynamic meta (fn of loaderData) — reflects loader output (tested via /meta-dynamic)
• 36. View transition meta tag present when hasViewTransition: true — BLOCKED: hasViewTransition accepted by renderPage but never passed from dispatchPage
• 37. Meta absent when not configured

API handlers (defineHandler)

• 38. GET /api/health — returns JSON with correct content-type
• 39. POST to handler — receives body, returns response (tested via /api/echo)
• 40. PUT/PATCH/DELETE — method routing works (tested via /api/echo)
• 41. Wrong HTTP method — returns 405
• 42. Handler returns custom headers — present in response (PUT /api/echo → x-custom: test-header)
• 43. Handler returns custom status codes (DELETE /api/echo → 204)
• 44. HEAD on page route — correct status and headers, empty body (HEAD / → 200, empty body)
• 45. HEAD on API handler (GET defined) — mirrors GET status/headers, empty body (HEAD /api/health → 200, empty body)
• 46. OPTIONS on page route — 200 with Allow: GET, HEAD, OPTIONS (unit-test verified; Vite CORS middleware intercepts in dev)
• 47. OPTIONS on API handler — 200 with Allow listing only defined methods (unit-test verified; Vite CORS middleware intercepts in dev)

Routing

• 48. Static route match (/, /demo)
• 49. Dynamic param route (/blog/[slug]) — params extracted correctly
• 50. Multiple dynamic params — all extracted (tested /users/42/posts/99)
• 51. Static routes take priority over dynamic (/blog/featured → static route)
• 52. Trailing slash handling — consistent behavior (both /demo and /demo/ → 200)
• 53. Non-existent route — 404
• 54. Nested route paths work (/api/health)
• 55. Catch-all route — GET /docs/a/b/c matches [...slug], params.slug === "a/b/c" (renders "Viewing: a/b/c")
• 56. Catch-all priority — catch-all matched last after static and dynamic routes (routes.gen.ts places *slug after all specific routes)
• 57. Route groups — (marketing)/pricing.tsx served at /pricing, group prefix stripped
• 58. URL-encoded segments — GET /blog/hello%20world decodes params.slug to "hello world"
• 59. Malformed percent-encoding — GET /blog/%ZZ doesn't throw, raw segment passed through (unit-test verified; Vite rejects malformed URLs in dev before reaching handler)

Error pages

• 60. Custom 404 page renders on missing route
• 61. Custom 500 page renders on unhandled error
• 62. Error page receives error context (status, message)
• 63. 500 page shows stack trace in dev mode (tested via /throw-test — stack trace visible in <pre>)
• 64. httpError(404) from route — renders 404 page
• 65. redirect("/") from route — 302 redirect, correct location header
• 66. Error in error page — circuit breaker returns bare HTML fallback (code-verified)
• 67. onError hook fires on error (code-verified — callOnError invoked in handleError)
• 68. Custom 403 page renders on httpError(403) (tested via /forbidden-test → 403 "Forbidden")
• 69. Error page render failure — console.error logged, bare HTML fallback returned (unit-test verified)
• 70. app.context() failure during 404 — error logged, 404 still returned (unit-test verified)

HMR / dev workflow

• 71. Edit route content — browser updates without full reload
• 72. Edit loader return value — new data appears
• 73. Add new route file — immediately accessible
• 74. Delete route file — returns 404
• 75. Add new template — usable by pages (tested: added minimal template to playground, /minimal-test renders with it)
• 76. routes.gen.ts regenerates on file add/remove
• 77. Syntax error in route — dev server shows error, doesn't crash
• 78. Fix syntax error — recovers without restart
• 79. Adding interactivity to a slot invalidates hydration manifest — dev server picks up change without restart (code-verified: handleHotUpdate rescans routes, invalidates manifest + virtual modules)

Navigation (MPA)

• 80. Click link from / to /demo — full page load, correct page (both pages return full HTML documents)
• 81. Click link from /demo to / — works
• 82. Browser back/forward — correct pages (MPA — browser handles natively)
• 83. View transitions fire between navigations — BLOCKED: hasViewTransition not wired in dispatch

Codegen CLI

• 84. node dist/cli.js generates framework.gen.d.ts and routes.gen.ts in src/
• 85. --src flag redirects output to specified directory
• 86. Missing source directory exits with code 1 and prints error

CLI scaffolder

• 87. pnpm create sundayceo my-app — creates project directory (unit-test verified)
• 88. Generated project has correct package.json with name substituted (unit-test verified; placeholder {{name}} replaced)
• 89. Dotfiles generated correctly (_gitignore → .gitignore) (unit-test verified)
• 90. Generated project runs pnpm install + pnpm dev successfully (tested with local file deps — dev server starts on port 3099)
• 91. Generated project's index page renders (scaffolded page renders: "Welcome to your new project.")

Production build

• 92. pnpm build completes without errors
• 93. Built output is valid ESM
• 94. Built output runs on target (Cloudflare Workers or Node) (wrangler dev serves all routes on port 8787)
• 95. All routes work in production mode (all routes return 200; API returns JSON; 404 handled)
• 96. Hydration works in production mode (browser-verified: Counter increments on click via wrangler)
• 97. Static pages have zero JS in production (zero <script> tags on static / route)
• 98. Asset paths resolve correctly in built output (content-hashed /assets/main-B-W3Mz-R.js loads and hydrates)
• 99. Two-pass build produces dist/client/ with hashed JS bundles for interactive slots
• 100. Client build skipped when project has no interactive slots — no dist/client/ created (code-verified: returns undefined when virtualEntries is empty)
• 101. Server bundle contains resolved hydration asset map, no __SUNDAYCEO_HYDRATION_ASSETS__ placeholder

Platform context

• 102. Cloudflare entry shim passes { env, ctx } to handler (verified in built entry.cloudflare.js)
• 103. Context factory receives platform object
• 104. Custom context values available in loaders
• 105. Platform undefined in dev — doesn't crash

Type safety (dev experience)

• 106. Autocomplete works on definePage route paths (RouteMap generated with all routes)
• 107. Loader return type flows into defineSlots loaderData
• 108. Params inferred from route path string (RouteMap has { slug: string }, { id: string; postId: string })
• 109. Type error on wrong slot name — ENHANCEMENT Enhancement: compile-time slot name validation #166: SlotMap accepts any string
• 110. Type error on wrong handler method

Hydration edge cases (added 2026-05-17, manual testing)

• 111. Edit static slot to interactive (add useState) — dev server picks up change, hydration script appears without restart (code-verified: handleHotUpdate rescans + invalidates)
• 112. Edit interactive slot to static (remove useState) — hydration script disappears, zero JS (code-verified: manifest recomputed, module invalidated)
• 113. Hydration mismatch — SSR HTML matches client render (no React console warnings) (browser-verified on /demo — zero mismatch warnings)
• 114. Multiple interactive slots on same page — each hydrates independently (tested /full-hydrate — 3 boundaries, 3 data scripts, 3 module scripts)
• 115. Interactive slot with loaderData — JSON data block correctly serialized and deserialized (tested /demo — JSON block contains full loader output)
• 116. Interactive slot with conditional rendering — both branches hydrate correctly (architecture supports this — hydration wraps full slot content)

Cloudflare Workers runtime (tested via apps/production-test + wrangler)

• 117. wrangler dev serves SSR pages correctly (all routes return 200 with correct HTML)
• 118. Static assets (client JS chunks) served via Workers static assets (content-hashed JS bundle served at /assets/main-B-W3Mz-R.js)
• 119. Hydration script src resolves to correct hashed chunk (<script type="module">import "/assets/main-B-W3Mz-R.js";</script>)
• 120. Interactive slot hydrates in Workers runtime (browser-verified: Counter increments to "Count: 3" after 3 clicks)
• 121. Static pages have zero JS network requests in Workers runtime (zero <script> tags on /)
• 122. Cold start latency acceptable (< 50ms for SSR) (measured ~4ms TTFB via curl)

Round 2 complete — 2026-05-16

Tested on main @ 4228a11 (post PR #162).

Results: 64/85 pass, 13 blocked/fail, 8 skipped

New playground routes created

• /async-loader — async loader test
• /request-test — query param in loader
• /blog/[slug] — dynamic param
• /blog/featured — static priority over dynamic
• /users/[id]/posts/[postId] — multi-param
• /context-test — app context in loader
• /throw-test — loader throws
• /meta-static, /meta-dynamic — meta tag tests
• /partial-slots, /typo-slot — slot validation tests
• /api/echo — multi-method handler (GET/POST/PUT/DELETE)
• app.ts updated: context returns { appName: "playground" }, onError hook added

Bugs filed

Issue	Severity	Items blocked
#163	Low	1 (item 18)
#164	High	10 (items 21-27, 30, 64, 74)
#165	Medium	1 (item 48)
#166	Low (enhancement)	1 (item 84)

#164 is the big one — hydration pipeline exists but isn't connected. All per-slot interactivity is dead code in production.
