SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires playwright, diff.

What problem does it solve?

Local QA testing and dogfooding across web apps can be slow, brittle, and hard to reproduce; gstack provides a lightweight, local headless browser workflow that automates navigation, interaction, diffing, and evidence capture.

Core Features & Use Cases

Persistent headless browser for QA, with Playwright-based automation and a CLI to run tests locally.
Diff before/after, take annotated screenshots, and collect text/HTML evidence for bug reports and design reviews.
Use cases include validating deployments, exploring user flows, and gathering reproducible bug evidence for handoffs.

Quick Start

Run a basic local QA workflow to validate a page and capture evidence.

FAQPage Schema

How do I automate local QA testing with a headless browser and capture bug evidence?▼

Automated QA testing uses a local headless browser workflow to navigate web apps, interact with elements, and capture annotated screenshots with diff evidence for bug reports.

What is browser diffing and how does it help with dogfooding?▼

Browser diffing compares before and after states of a web page to detect visual or structural regressions, producing repeatable evidence artifacts for design reviews and bug handoffs.

How do I take annotated screenshots during Playwright automation for reproducible bug reports?▼

Annotated screenshots are captured during Playwright-based browser automation by navigating user flows and collecting text, HTML, and visual evidence to document testing states.

Does this local QA workflow require a predefined testing setup to run properly?▼

Yes, the local QA workflow requires a Playwright-based browser environment and a defined testing workflow to orchestrate navigation, interaction, and evidence capture with repeatable results.

What's the best way to validate web app deployments locally without manual inspection?▼

Validating deployments locally is best handled by an automated headless browser workflow that executes navigation, verifies state, and captures diff evidence without manual inspection.

Can I use this for exploring user flows and gathering reproducible bug evidence for handoffs?▼

Yes, you can use the local headless browser workflow to explore user flows, validate page states, and gather reproducible text, HTML, and screenshot evidence for bug handoffs.
