SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates slow, unreliable manual QA by letting you navigate a site headlessly, verify states, and collect screenshot evidence that’s easy to share when something breaks.

Core Features & Use Cases

  • Headless browsing and interaction: Navigate to URLs, inspect pages, interact with elements, and validate UI state transitions for flows like login, signup, checkout, and feature dogfooding.
  • Verification with before/after diffs: Capture baseline and diff changes after actions so you can confirm what actually changed.
  • Bug evidence for reporting: Take annotated screenshots and responsive layout captures to attach concrete proof of failures, regressions, and deployment issues.
  • Coverage for real QA scenarios: Test responsive layouts, forms with validation, uploads, dialogs, and authenticated pages via cookie import.

Quick Start

Ask the AI to run gstack browse and verify whether a specific URL loads and behaves correctly, capturing screenshots and diffs as evidence.

Frequently Asked Questions about gstack-main

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

FAQPage Schema
How do I automate headless browser testing to capture screenshot evidence for bug reports?

Headless browser testing automates site navigation and UI interaction to verify state changes, capturing annotated screenshots and responsive layout captures as concrete proof for bug reports.

Can I test authenticated pages and handle cookie imports during deployment verification?

Authenticated testing supports cookie import to verify protected pages, enabling end-to-end user flow validation like login, signup, and checkout during deployment checks.

What is the best way to perform responsive layout validation across different viewport sizes?

Responsive layout validation uses a headless browser to capture baseline snapshots and diff changes, confirming what actually changed across various viewport sizes during UI testing.

How do I verify UI state transitions and generate before and after diffs for forms and uploads?

UI state verification captures baseline and diff changes after actions like form validation and file uploads, confirming what actually changed through before and after screenshot comparisons.

Does headless QA testing work for end-to-end user flows like checkout and feature dogfooding?

Headless QA testing drives a fast browser to navigate pages and interact with UI elements, validating end-to-end user flows like checkout, signup, and feature dogfooding with screenshot evidence.

What are the limitations of using a headless browser for deployment checks and dialog handling?

Headless browser testing requires the gstack browser binary for actions like goto, snapshot, and assertions, limiting deployment checks and dialog handling to environments where this binary is available.
