SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Local web developers and QA teams need reliable, repeatable tests for local web applications. This Skill provides a Python-based Playwright toolkit to automate UI checks, capture screenshots, and observe browser logs, reducing manual debugging time.

Core Features & Use Cases

  • Playwright-driven UI testing for local applications
  • Automated screenshot capture and browser log collection
  • Server orchestration with scripts/with_server.py for single or multi-server setups
  • Reference examples and runnable templates to accelerate adoption

Quick Start

Use the skill to start a local server and run your first Playwright automation:

  • Start a single server: python scripts/with_server.py --server "npm run dev" --port 5173 -- python your_automation.py
  • Start multiple servers: python scripts/with_server.py --server "cd backend && python server.py" --port 3000 --server "cd frontend && npm run dev" --port 5173 -- python your_automation.py
  • Create an automation script with Playwright logic: from playwright.sync_api import sync_playwright with sync_playwright() as p: browser = p.chromium.launch(headless=True) page = browser.new_page() page.goto('http://localhost:5173') page.wait_for_load_state('networkidle') # your automation steps browser.close()

Frequently Asked Questions about webapp-testing

High-intent search queries and answers about installing and using this skill.

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

Playwright web app testing is automated by writing native Python scripts that launch a browser, navigate to your local application, and perform UI verification steps. The skill provides runnable templates and helper scripts to manage servers during execution.

Can I test multiple local servers simultaneously in a single Playwright run?▼

Yes, multiple local servers are supported simultaneously. You can use the with_server.py helper script to orchestrate multiple server commands and ports before executing your Python Playwright automation script against the combined environment.

How do I capture screenshots and collect browser logs during UI testing?▼

Screenshot capture and browser log collection are handled natively within your Python Playwright automation scripts. You write native Playwright logic to navigate pages and trigger these capture functions to debug frontend UI issues automatically.

Do I need Python to run Playwright UI tests for local web applications?▼

Yes, Python and Playwright are required dependencies. Tests are written as native Python scripts using the Playwright sync API, meaning you need a local Python environment configured to execute the automation and server orchestration commands.

What is the best way to manage local servers before running web testing automation?▼

The best way to manage local servers is using the with_server.py helper script. It handles single and multi-server orchestration by accepting server commands and port arguments, ensuring your frontend and backend are running before your tests execute.
