Three rename + one substantial test rewrite:
- "tool calling tests" -> "Tool calling Tests"
- "Chat UI smoke (Playwright + Chromium)" -> "Chat UI Tests"
- "install.sh + `unsloth studio update --local`" -> "Studio Updating Tests"
Chat UI Tests was a 4-second pass-through (fill new password, send one
message, reload). Rewrote into a 15-section flow that runs ~30 seconds
locally and exercises the full Studio chat surface a real user touches:
1. Login form (username is hardcoded HIDDEN_LOGIN_USERNAME in
auth-form.tsx, so we only fill #password)
2. Composer mounts after auth
3. Composer toolbar (Send + Add Attachment)
4. Three distinct user turns with non-empty deterministic
assistant replies (verified locally: lengths 6/1/6 for
"hello"/"1"/"world" prompts)
5. Assistant action bar: Copy + Regenerate
6. Settings sheet open + close
7. Theme toggle via account menu (light <-> dark, with a
view-transition wait so the click doesn't race the animation)
8. Sidebar nav: New Chat, switch-back-to-previous-chat (history
persistence via threadId in IndexedDB)
9. Sidebar Search dialog
10. Sidebar collapse/expand
11. Reload + verify session JWT survives (the 2026.5.1 chat-history
regression killed the page entirely on reload; this catches it)
12. Post-reload turn proves inference still works
13. /api/health stays healthy
14. Negative-auth: old bootstrap pw -> 401, rotated pw -> 200
15. Zero pageerror events captured
The CI step that boots Studio + loads the model now rotates the
bootstrap password BEFORE calling /api/inference/load. /api/inference/
load is gated behind must_change_password=false; the previous flow
(login bootstrap -> load) was succeeding in CI by historical accident
and started failing locally. New flow:
bootstrap login -> change-password -> rotated login -> load model
Both passwords are exposed to the Playwright step via env, so the
test can drive /login with the rotated password AND assert the old
one is now 401.
Verified locally end-to-end against a real Studio install with
gemma-3-270m-it-GGUF UD-Q4_K_XL: all 15 sections pass, console.error
count = 0, total runtime ~30s.
