SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables automated testing of local web applications using Playwright, reducing time spent on manual UI validation by providing reliable, repeatable tests that run in real browsers.

Core Features & Use Cases

  • Browser Automation: Navigate to pages, interact with elements, fill forms, and verify UI behavior across different viewport sizes.
  • Debugging & Evidence: Capture screenshots and collect browser console logs to diagnose failures quickly.
  • Use Case: Integrate with local development workflows to continuously validate UI flows, regression tests, and cross-browser compatibility.

Quick Start

  • Ensure Node.js is installed on your machine.
  • Install Playwright (npm i -D playwright) if it's not automatically installed, then run a sample test script that navigates to http://localhost:3000 and asserts the page title.

Do I need Node.js installed to run Playwright UI automation tests?▼

You need Node.js installed to run Playwright UI automation tests, as the Skill relies on a Node.js runtime with automatic dependency handling to execute browser automation scripts.

Can I verify cross-browser behavior and different viewport sizes with Playwright?▼

You can verify cross-browser behavior and different viewport sizes with Playwright by configuring the browser automation APIs to launch tests across multiple real browsers and responsive layouts.

What is the best way to debug failing UI interactions in a local development workflow?▼

The best way to debug failing UI interactions in a local development workflow is to run repeatable Playwright tests that capture diagnostic outputs like screenshots and browser console logs for quick analysis.

Why are my web app test scripts not capturing browser console logs?▼

If your web app test scripts are not capturing browser console logs, ensure you are correctly utilizing the Playwright APIs designed to intercept and collect diagnostic outputs during the Node.js test execution.
