SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

QA and dogfooding of web apps require a reliable browser environment that can be scripted and reproduce issues. This Skill provides a fast headless browser workflow for automated testing, artifact collection, and proof-ready evidence.

Core Features & Use Cases

  • Navigate pages, interact with elements, and capture state with diff and annotated screenshots.
  • Verify responsive layouts and form interactions across pages, and produce bug evidence for PRs.
  • Use with Playwright-based automation to test on staging or production-like environments and generate repeatable deliverables.

Quick Start

Run /browse to start a headless QA session and verify a page.

FAQPage Schema
How do I automate end-to-end QA testing for web pages?▼

You can automate end-to-end QA testing by running a headless browser session to navigate pages, interact with elements, and capture state. This workflow validates staging environments and produces annotated screenshots as bug evidence.

Can I use Playwright to generate bug evidence for pull requests?▼

Playwright automation can generate bug evidence for pull requests by navigating web pages and capturing annotated screenshots. It verifies form interactions and responsive layouts, producing repeatable deliverables for regression testing.

What is the best way to collect proof-ready artifacts during regression testing?▼

The best way to collect proof-ready artifacts during regression testing is using a fast headless browser. It captures page states, diff comparisons, and annotated screenshots to reproduce bugs and validate pre-release environments.

How do I verify responsive layouts and form interactions in a staging environment?▼

You verify responsive layouts and form interactions by running automated browser sessions against staging environments. The headless browser navigates pages, interacts with forms, and captures visual state to ensure UI consistency.

Does headless browser testing work for reproducing bugs in production-like environments?▼

Headless browser testing works for reproducing bugs in production-like environments by applying scripted automation. It reliably replicates user interactions, captures the exact page state, and outputs diff screenshots for analysis.

Why use a headless browser for pre-release validation instead of manual testing?▼

A headless browser provides faster pre-release validation than manual testing by automating scripted interactions and capturing state. It ensures repeatable regression testing and generates proof-ready evidence without manual screenshot collection.
