chromium-local-smoke-tests

Context

Use this when the team wants a small, always-on Chromium browser slice that proves real page interaction honestly without creating browser-specific MCP tools.

Pattern

• Prefer Edge + local static HTML for the deterministic slice, then pair it with one stable public-web page for required internet coverage.
• Keep the scope to page content discovery first: landmarks, ARIA-labeled inputs, and buttons.
• Launch Edge as an app window with startup hygiene, --force-renderer-accessibility, and an isolated --user-data-dir for reliability.
• Keep the public tier to a stable browser-testing page (for example https://demo.playwright.dev/todomvc/) and assert only long-lived page content such as labeled inputs or links.
• Keep browser chrome, logins, and ambient profile state out of the default slice.

Good first assertions (local tier)

• Landmark or navigation container is discoverable.
• ARIA-labeled search box resolves as Edit.
• ARIA-labeled primary action resolves as Button.
