SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Fast, private QA testing of web apps by providing a blazing-fast headless browser that can load pages, interact with elements, and verify outcomes without a full UI.

Core Features & Use Cases

  • Deterministic browser actions: load pages, click, type, fill forms, capture screenshots, and validate states.
  • State inspection & diffing: compare page outputs across navigations, capture ARIA snapshots, and diff before/after states for regression checks.
  • Automation workflows: run scripted test flows, verify responsive layouts, and debug issues with annotated evidence.
  • Use Case: QA engineers can script a login flow, verify UI changes after a deployment, and produce evidence (screenshots, diffs) for bug reports.

Quick Start

Start the QA session by loading a URL with a simple navigation command, then perform actions like filling a form or taking a screenshot to verify behavior.

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

You can automate QA testing using a Playwright-backed headless browser to script deterministic actions like loading pages, clicking elements, filling forms, and capturing screenshots to verify web application outcomes.

Can I use Playwright to verify UI regression after a deployment?

Yes, you can capture ARIA snapshots and diff before/after states across navigations using a headless browser, producing annotated evidence like screenshots to verify UI changes and debug issues after a deployment.

What is the best way to script a login flow for automated testing?

The best way to script a login flow is using a command interface that performs deterministic browser actions: load the URL, fill the form fields, click submit, wait for state changes, and validate element visibility.

Does headless browser testing support responsive layout verification?

Yes, headless browser testing supports automation workflows that run scripted test flows to verify responsive layouts across different URLs, capturing screenshots and inspecting DOM states to ensure consistent rendering.

What state checks can I perform during web automation testing?

During web automation testing, you can perform state checks including verifying element visibility, inspecting text content, evaluating DOM states, and capturing diffed snapshots for regression verification across navigations.

How does error handling work for URL validation in headless browsing?

Headless browsing includes robust error handling with URL validation and safe defaults, ensuring that automated test flows fail gracefully and provide accurate evidence when navigation or element interaction issues occur.
