SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Frontend ecosystems are complex due to varying DOM structures, CSS/JS interactions, and accessibility requirements across frameworks; this Skill provides a Playwright-based protocol to validate DOM topology, layout behavior, and a11y across framework boundaries, reducing silent regressions.

Core Features & Use Cases

  • Core Pillars: Read Before Write; CSS-First, JS-Augment; Measure, Don't Assume
  • Five Principles and Playwright in loop: hypothesis validation, layout tests, and CI-ready checks
  • Framework coexistence and reactive performance checks for multi-framework pages
  • A11y: keyboard focus, aria-live, and native HTML priority rules
  • Cross-framework support including vanilla HTML/JS, Vue, React, and vendor widgets
  • Reference-driven guidance for DOM topology, CSS/JS boundaries, and data-flow consistency

Quick Start

Install and run the Playwright-based validation suite against your frontend pages to validate DOM topology, layout, and accessibility.

Frequently Asked Questions about frontend-with-playwright

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

FAQPage Schema
How do I test frontend layout and accessibility across multiple frameworks?▼

Cross-framework frontend testing validates DOM topology, layout behavior, and a11y across boundaries using Playwright. It applies structured principles to prevent silent regressions in vanilla HTML/JS, React, Vue, and vendor widgets.

Can I use Playwright to verify DOM topology on pages with coexisting frameworks?▼

Playwright verifies DOM topology on multi-framework pages by testing framework coexistence. It applies reactive performance checks and validates data-flow consistency across vanilla HTML/JS, React, Vue, and vendor widgets.

What's the best way to prevent silent frontend regressions in a CI pipeline?▼

CI-ready frontend regression checks prevent silent failures by enforcing hypothesis validation and layout tests with Playwright in the loop. This measures actual DOM topology and a11y behavior rather than assuming component states.

Does frontend testing with Playwright support native HTML accessibility rules?▼

Playwright frontend testing enforces native HTML priority rules for accessibility. It validates keyboard focus, aria-live regions, and a11y compliance using a CSS-first, JS-augment approach to ensure structured verification.

How do I validate frontend behavior without assuming CSS and JavaScript boundaries?▼

Frontend behavior validation uses 'Read Before Write' and 'Measure, Don't Assume' principles with Playwright. It checks DOM topology and layout behavior directly, ensuring reference-driven guidance for CSS/JS boundaries.
