SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

gstack automates QA testing and site dogfooding using a fast headless browser. It lets you navigate pages, interact with elements, verify state, diff before/after, take annotated screenshots, test responsive layouts, forms, uploads, dialogs, and capture bug evidence.

Core Features & Use Cases

  • Automated browser-based QA and site verification during deployments.
  • Navigate pages, interact with elements, verify state, take annotated screenshots, and compare diffs to catch regressions.
  • Use case: you deploy a web app and want a repeatable, scriptable QA flow that reports visual issues and failing interactions.

Quick Start

Open a site in gstack and run a quick test flow to verify navigation, state, and screenshots.

FAQPage Schema
How do I automate QA testing with a headless browser for deployment validation?▼

Automate QA testing with a headless browser by programmatically navigating pages, interacting with elements, and verifying state to validate deployments. This skill scripts repeatable flows to capture screenshots and report failing interactions or visual regressions.

What is the best way to capture bug evidence and visual diffs during UI regression checks?▼

The best way to capture bug evidence and visual diffs during UI regression checks is to automate before and after screenshots. This skill compares visual diffs, verifies element state, and collects annotated screenshots as reliable bug evidence.

Can I test responsive layouts, forms, uploads, and dialogs without a graphical browser?▼

Yes, you can test responsive layouts, forms, uploads, and dialogs without a graphical browser. A fast headless browser executes programmatic navigation and element interaction to verify these UI components across multiple pages.

Do I need any browser dependencies to run automated site dogfooding scripts?▼

No browser dependencies are required to run automated site dogfooding scripts. This skill operates independently to apply programmatic navigation, state verification, and screenshot capture for deployment validation and regression checks.

How does headless browser automation handle element interaction and state verification across multiple pages?▼

Headless browser automation handles element interaction and state verification by programmatically navigating multiple pages. It applies scripted flows to interact with UI elements, verify application state, and capture annotated screenshots for QA testing.
