Run 25494399543 / job 74810247593 progressed past the change-password
flow + composer-mount + default_models[0] check (so commits d35bf6a
and fdf7f94's Chromium fixes are working) but then crashed on
`shoot('03b-default-model-button')` with:
playwright._impl._errors.TimeoutError:
Page.screenshot: Timeout 30000ms exceeded.
Call log:
- taking page screenshot
- waiting for fonts to load...
- fonts loaded
Page.screenshot waits for the page's webfonts to be resolved before
snapshotting. On macos-14 free runners under --single-process
Chromium, font loading for the Studio chat page (Inter / Geist Mono)
crowds the 30s default. Two changes:
1. Bump screenshot timeout to 90_000ms.
2. Wrap shoot() in try/except. Screenshots are diagnostic artifacts
uploaded for human triage; a failure to capture one should never
fail the test. The actual UI assertions live in step()/info()/
wait_for() calls, which are unaffected.
Adds animations='disabled' for deterministic captures (frozen CSS
transitions). Both playwright_chat_ui.py and playwright_extra_ui.py
get the same treatment.

"""Studio extra-UI Playwright test.
|
|
|
|
Covers the user-visible surfaces that the main chat-UI test doesn't:
|
|
|
|
1. Compare tab (/chat?compare=...): assign two models, send 2 prompts,
|
|
assert both panes respond.
|
|
2. Recipes editor (/data-recipes/$recipeId): click first template,
|
|
verify the recipe-studio canvas mounts, open + close the Preview
|
|
dialog.
|
|
3. Export route (/export): chat-only mode redirects to /chat;
|
|
non-chat-only mode shows the export form fields.
|
|
4. Studio training route (/studio): chat-only mode redirects;
|
|
non-chat-only verifies the tabs + sections exist.
|
|
5. Settings dialog tabs: Cmd/Ctrl-, opens the dialog; cycle through
|
|
each tab and verify it isn't blank.
|
|
|
|
The test assumes Studio is freshly booted (must_change_password=true)
|
|
on BASE_URL with the bootstrap password in STUDIO_OLD_PW. It does its
|
|
own change-password through the UI + model load via /api/inference/load,
|
|
matching the pattern in playwright_chat_ui.py.
