SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Provides a reproducible, developer-friendly way to run Playwright-driven tests and interactions against local web applications while managing server lifecycles and avoiding flaky timing issues.

Core Features & Use Cases

  • Server Orchestration: scripts/with_server.py launches one or more local servers, waits for ports to be ready, runs a command, and reliably tears down processes.
  • Playwright Automation Examples: examples show element discovery, static HTML automation, screenshot capture, and console log collection patterns.
  • Reconnaissance-Then-Action Pattern: guidance to wait for networkidle, inspect rendered DOM, discover selectors, then execute deterministic actions for robust UI tests.
  • Use Case: Run a frontend and backend locally, discover UI selectors from runtime DOM, capture screenshots and console logs, and validate frontend behavior in CI-like workflows.

Quick Start

Run the scripts/with_server.py helper with --help, start your local app(s), then run a Playwright script that navigates to the local URL, waits for networkidle, inspects the DOM, and captures screenshots and logs.

FAQPage Schema
How do I automate Playwright end-to-end testing for a local web app?

You can automate Playwright end-to-end testing for a local web app by launching servers, polling ports until ready, running scripts to discover UI selectors, and capturing screenshots for validation.

How do I manage local server lifecycles during browser automation testing?

Manage local server lifecycles during browser automation testing using a Python helper script that launches servers, waits for ports to be ready, runs Playwright scripts, and reliably tears down processes.

How do I capture console logs and screenshots with Playwright?

Capture console logs and screenshots with Playwright by running automation scripts that navigate to a local URL, wait for networkidle, inspect the rendered DOM, and collect browser logs and screen captures.

Can I test multi-server development setups with Playwright?

Yes, you can test multi-server development setups with Playwright by using the server orchestration helper to launch multiple local servers and wait for their respective ports to be ready before executing tests.

What is the best way to find UI selectors reliably during webapp testing?

The best way to find UI selectors reliably during webapp testing is applying a reconnaissance-then-action pattern: wait for networkidle, inspect the rendered DOM to discover selectors, then execute deterministic actions.

Do I need Python to run Playwright tests against local web apps?

Yes, you need Python with Playwright available in your environment to run the automation scripts, interact with local web apps, and utilize the included server management helper.
