millioncoOfficial·8 Agent Skills Included

expect

Test code changes in a real browser automatically with AI

Tests your code changes in a real browser by reading git diffs, generating a test plan, and running it with Playwright. Eliminates manual QA clicking, brittle test scripts, and selector maintenance by letting your coding agent verify its own work. Checks performance, security, broken links, and UI issues, then reports failures so the agent can fix and re-verify automatically.

Frequently Asked Questions

FAQPage Schema

How to install Expect?▼

Run `npx skills add millionco/expect --all -g -y` in your terminal to install all skills in this suite globally.

What does Expect do?▼

Expect reads your git changes, generates a test plan, and runs it in a real browser with Playwright. It checks for performance, security, broken links, and UI issues, then reports what is broken so your agent can fix it.

Which AI agents work with Expect?▼

Expect works with Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode, and Factory Droid. It auto-detects installed agents or lets you pick one with a flag.

How is Expect different from Playwright or Cypress?▼

Instead of writing scripts and maintaining selectors, Expect reads your code changes and tests them in a real browser automatically, using your real login cookies for authenticated testing.

Does Expect work in CI pipelines?▼

Yes. Use the --ci flag or the add github-action command to test every pull request automatically in headless mode with a 30-minute timeout.
