SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill provides a guided approach to testing local web applications by leveraging Playwright to verify frontend functionality, debug UI behavior, and systematically collect evidence such as screenshots and browser logs.

Core Features & Use Cases

  • Automated UI verification: Scripted checks to ensure key UI elements render and respond correctly.
  • Debugging and diagnostics: Capture DOM state, network activity, and console logs to diagnose issues.
  • Evidence collection: Automatically take screenshots and preserve logs for reporting.
  • Use Case: Validate a local app's login flow by navigating to the login page, waiting for network idle, and asserting the presence of a login button.

Quick Start

  1. Install Playwright for Python and initialize engines: pip install playwright && playwright install
  2. Start your local server using the provided helper: python scripts/with_server.py --server "npm run dev" --port 5173 -- python your_automation.py
  3. Create a simple automation script using Playwright to open http://localhost:5173, wait for network idle, and capture a screenshot.

FAQPage Schema
How do I automate local web app testing with Playwright?

Automate local web app testing with Playwright by starting a local server, navigating pages, waiting for network idle, and asserting element states to verify frontend functionality. Scripts can systematically capture screenshots and browser logs.

Can I capture browser logs and screenshots during UI testing?

Yes, capture browser logs and screenshots during UI testing by scripting Playwright to collect evidence. You can automatically take screenshots and preserve console logs for reporting and debugging UI behavior.

How do I start a local server and run Playwright scripts together?

Start a local server and run Playwright scripts together using a server helper script. Execute a command like 'python scripts/with_server.py --server "npm run dev" --port 5173 -- python your_automation.py' to manage both processes.

What's the best way to verify a local app's login flow with UI testing?

Verify a local app's login flow by navigating to the login page, waiting for network idle, and asserting the presence of a login button. Playwright scripts check that key UI elements render and respond correctly.

Do I need to install Playwright engines to test local web applications?

Yes, you need to install Playwright engines to test local web applications. Run 'pip install playwright && playwright install' to set up the Python package and initialize the required browser engines for automation.

Why use Playwright instead of other tools for local web app testing?

Use Playwright for local web app testing to script checks across browsers, wait for network idle, and capture DOM state. It provides systematic evidence collection like screenshots and browser logs for frontend debugging.
