Expect is a CLI tool and MCP skill that reads your git changes, generates a test plan, and runs it in a real browser using Playwright. It integrates with coding agents like Claude Code, Codex, and Cursor to automatically find regressions and issues, then lets the agent fix them.

Use cases

  • test my agent's code changes in a real browser
  • automated QA for pull requests in CI
  • find broken hover states, dead links, and missing metadata
  • check performance metrics like INP and LCP on my web app
  • run security checks on npm dependencies and CSRF vulnerabilities
  • simulate logged-in users to catch regressions
  • add browser testing to Claude Code or Cursor without writing Playwright scripts

When to choose

  • You want automated browser-based QA of code changes without maintaining test scripts or selectors
  • You use AI coding agents and want them to find and fix regressions themselves
  • You need PR-level testing in CI with real cookies and real browser behavior

When to avoid

  • You need mobile or cross-browser testing (not yet supported)
  • You want deterministic, hand-written test suites with explicit assertions
  • You need a hosted or enterprise testing service (not yet available)
