# The analytics page in a real Chrome, over a deployment of 490 accounts.

# Starts crates/didbot-serve/examples/analytics_fixture.rs on a free loopback
# port, waits while it seeds, then runs
# crates/didbot-serve/tests/browser/analytics.mjs against it with Playwright
# driving the Chrome on this machine. Screenshots of each tab, at desktop and
# phone widths, are left in DIDBOT_ANALYTICS_SHOTS.
#
# Opt-in, not a commit hook: seeding takes a minute in a debug build and it
# wants a browser. scripts/ci.sh runs it when DIDBOT_E2E=1.

# Usage: scripts/test-analytics-browser.sh
