SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Web UI testing is brittle and time-consuming without a structured approach. This skill provides a decision tree, patterns, and practical guidance to test web applications reliably with Playwright.

Core Features & Use Cases

  • Decision-tree guidance for static vs dynamic apps and when to start the server
  • Reconnaissance-then-action pattern to discover selectors from live pages
  • Server lifecycle management and basic Playwright setup for deterministic tests

Quick Start

Install Playwright, write a basic test using the reconnaissance-then-action pattern, and run it against a local server.

FAQPage Schema
How do I write reliable Playwright tests for web UI automation?

Reliable Playwright tests use a reconnaissance-then-action pattern to discover selectors from live pages, ensuring robust UI automation. This approach prevents brittle tests by dynamically identifying elements instead of relying on static, hardcoded selectors.

What's the best way to manage the local server lifecycle during end-to-end browser testing?

Server lifecycle management handles starting and stopping local development servers to ensure deterministic tests. This process isolates the test environment, preventing external state changes from causing flaky end-to-end browser testing failures.

How do I discover UI selectors dynamically during Playwright test automation?

You can discover UI selectors dynamically by applying a reconnaissance-then-action pattern during Playwright test automation. This method inspects the live web page state first, allowing the test to locate elements accurately before executing interaction actions.

Do I need a different testing strategy for static versus dynamic web apps?

Yes, testing static versus dynamic web apps requires different strategies determined by a decision tree. This guidance dictates when to start the local server and how to handle UI regression across varying application rendering behaviors.

Can I integrate Playwright UI automation into CI pipelines for regression testing?

Yes, Playwright UI automation can be integrated into CI pipelines for regression testing. The skill provides setup patterns and server lifecycle management to execute deterministic tests consistently across local development servers and automated environments.

Why does my webapp testing fail due to brittle selectors?

Webapp testing fails due to brittle selectors when tests rely on static assumptions rather than live page inspection. Using a reconnaissance-then-action pattern discovers selectors from live pages, mitigating brittleness and ensuring robust test execution.
