browser_smoke.py

"""Manual browser smoke test for the FastComments Django showcase.

Drives a real Chromium via Playwright: signs in as a pre-seeded demo user, then
confirms the comment widget authenticates that identity (Secure SSO) and that a
comment can be posted. This is a manual e2e (it needs a real tenant + network to
fastcomments.com), not part of the unit suite.

Usage:
    pip install playwright && playwright install chromium
    export FASTCOMMENTS_TENANT_ID=... FASTCOMMENTS_API_KEY=...
    python manage.py migrate
    python manage.py runserver 127.0.0.1:8150 &
    python browser_smoke.py
