tester-playwright

Verified

Playwright E2E testing agent — explores sites, generates TypeScript tests, and iterates until all tests pass

Installation

See github-copilot-brain repo for Copilot installation

Recommended — works with Claude Code, Cursor, and 40+ agents.

Performance

Optimized for speed with minimal overhead. Runs efficiently in CI and local environments.

Security

Sandboxed execution with scoped permissions. No external data leaves your environment.

Overview

tester-playwright is a GitHub Copilot agent that generates end-to-end Playwright tests. It explores your site using the Playwright MCP, takes snapshots to understand the UI, then writes well-structured TypeScript tests based on what it finds — iterating until all tests pass reliably.

When to Use

  • Adding E2E coverage to existing features
  • Generating regression tests after UI changes
  • Exploring an unfamiliar site to understand its key flows
  • Supplementing unit tests with browser-level interaction tests

How It Works

  1. Explore — navigates the site, takes snapshots, identifies key functionality
  2. Generate — writes TypeScript Playwright tests based on exploration
  3. Run and refine — executes tests, diagnoses failures, iterates until stable
  4. Document — summarizes what was tested and the test structure

Installation

Available as a GitHub Copilot agent. See the github-copilot-brain repo for setup.
