SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The gstack skill automates a fast, headless browser workflow to accelerate QA testing, enabling reliable verification of web flows without manual clicks.

Core Features & Use Cases

  • Drive a browser to load pages, interact with elements, and collect evidence (screenshots, DOM diffs, and test reports).
  • Diff baseline and post-action states, annotate screenshots, and verify responsive layouts for multiple viewports.
  • Integrate into developer workflows for CI validation, bug hunting, and design dogfooding.

Quick Start

Run a quick QA session by invoking the browse capability to launch the headless browser and drive a test flow.

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

FAQPage Schema
How do I automate QA testing with a headless browser?

Headless browser QA testing automation drives a browser to load pages, interact with elements, and capture evidence like screenshots and DOM diffs. The gstack skill automates these workflows to verify web flows without manual clicks across local and staging environments.

Can I capture screenshots and DOM diffs during Playwright test automation?

Yes, Playwright test automation can capture screenshots and DOM diffs to support reproduce-and-fix cycles. The gstack skill exports these artifacts along with test reports, diffing baseline and post-action states to annotate visual evidence for responsive layouts.

What is the best way to diff baseline and post-action states for web applications?

Diffing baseline and post-action states for web applications involves comparing DOM states and screenshots before and after interactions. The gstack skill automates this diffing process, exporting reports and annotated screenshots to identify visual and structural changes.

Does this headless browser testing workflow support multiple viewports for responsive layouts?

Headless browser testing workflows support verifying responsive layouts for multiple viewports. The gstack skill drives the browser to load pages and interact with elements across different viewport sizes, capturing screenshots to validate responsive design behavior.

How do I integrate end-to-end QA workflows into CI validation?

Integrating end-to-end QA workflows into CI validation requires automating browser interactions and exporting test reports. The gstack skill automates navigation, form interaction, and result diffs, enabling developers to run reliable verification checks during continuous integration cycles.

When do I need automated browser workflows for bug hunting?

Automated browser workflows for bug hunting are needed when verifying web application flows without manual clicks. The gstack skill automates loading pages, interacting with elements, and capturing evidence like screenshots and reports to support design dogfooding and reproduce-and-fix cycles.
