SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Automates testing of local web applications using Playwright. This Skill provides a Playwright-based framework to automate frontend tests, capture screenshots, and inspect browser logs to streamline QA on your local environment.

Core Features & Use Cases

  • Automated UI testing: Validate frontend behavior across pages and states using Playwright scripts.
  • Evidence capture: Automatically save screenshots and logs to document test results.
  • Local-server testing: Easily run tests against a locally started server via the included with_server.py helper.

Quick Start

Install Python 3.x and Playwright, initialize browsers, and run a simple test script. Example commands:

  • pip install playwright
  • python -m playwright install
  • Create a test script under scripts/ (e.g., tests/ui_test.py) and run: python scripts/ui_test.py
  • To run tests against a local server: python scripts/with_server.py --server "npm run dev" --port 5173 -- python tests/ui_test.py

FAQPage Schema
How do I automate testing of a local web application with Playwright?

Automate testing with Playwright by installing Python 3 and the Playwright library, initializing browsers with `python -m playwright install`, then creating test scripts in the scripts/ directory to validate UI behavior, capture screenshots, and inspect browser logs against your local server.

Can I run Playwright tests against a locally started development server?

Yes, use the included with_server.py helper to run tests against a local server. Example: `python scripts/with_server.py --server "npm run dev" --port 5173 -- python tests/ui_test.py` automatically starts your dev server, runs tests, and captures results.

What browsers does Playwright support for local web app testing?

Playwright supports Chromium, Firefox, and WebKit browsers for testing. Install any compatible browser via `python -m playwright install` to run automated UI tests and capture screenshots across different rendering engines locally.

How do I capture screenshots and browser logs during automated testing?

Playwright automatically saves screenshots and logs as evidence during test execution. Write test scripts using Playwright's API to capture visual state and inspect browser console output, storing results locally for QA documentation and debugging.

What are the prerequisites to start testing with Playwright locally?

You need Python 3, the Playwright library installed via pip, initialized browsers, and a test script. The Skill provides helper utilities like with_server.py to orchestrate tests against a local development environment without additional configuration.

Does Playwright work for end-to-end frontend verification across multiple page states?

Yes, Playwright automates end-to-end UI testing to validate frontend behavior across pages and states. Write scripts under scripts/ to test navigation, interactions, and visual changes, then run them against your local server to verify complete workflows.
