SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires bun, git, jq, and includes scripts (resource) components.

What problem does it solve?

This skill solves the challenge of manual site testing and QA by providing a persistent, headless browser environment that can interact with web elements, verify state, and capture visual evidence.

Core Features & Use Cases

  • Automated QA: Navigate pages, interact with forms, and verify UI state across different layouts.
  • Visual Regression: Capture annotated screenshots and perform diffs to identify visual bugs before deployment.
  • Site Dogfooding: Simulate user flows like login, checkout, and navigation to ensure production readiness.

Quick Start

Use the gstack skill to navigate to the login page and take a screenshot of the dashboard after authentication.

Frequently Asked Questions about gstack

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

FAQPage Schema
How do I automate QA testing for complex user flows in a headless browser?▼

Automated QA testing for complex user flows is handled by providing a persistent headless Chromium environment that programmatically navigates pages, interacts with forms, and verifies UI state. This simulates login and checkout processes to ensure production readiness.

What is the best way to detect visual bugs and perform visual regression testing before deployment?▼

Visual regression testing detects visual bugs by capturing annotated screenshots within the headless browser environment and performing image diffs. This identifies layout discrepancies and visual errors before deployment.

Do I need to install the gstack binary locally to run automated browser testing?▼

Yes, local installation of the gstack binary and compatible environment configuration are required to execute browser commands. The environment also depends on bun, git, and jq to run the testing scripts.

Can I use this to verify responsive layouts across different screen sizes?▼

Yes, you can verify responsive layouts across different screen sizes. The headless browser environment facilitates responsive layout testing by interacting with web elements and capturing visual evidence across varied viewport configurations.

Does headless Chromium testing work for site dogfooding and production readiness checks?▼

Headless Chromium testing works for site dogfooding by simulating user flows like login, checkout, and navigation. This programmatic browser interaction verifies application state and ensures production readiness.
