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

Automate QA testing by driving a persistent headless Playwright browser from a CLI. It keeps state in a local browser daemon, enabling fast, repeatable test execution across deployments without manual setup.

Can I take annotated screenshots and snapshots for regression verification?▼

Yes, you can capture snapshots, diff state, and take annotated screenshots for regression verification. This provides visual evidence to verify UI behavior and compare changes across responsive layouts.

How do I reproduce bugs and interact with web pages automatically?▼

Reproduce bugs by using CLI commands like goto, click, and fill to navigate and interact with web pages. The persistent browser session maintains state to reliably reproduce issues and gather evidence.

Does this QA automation tool work with Playwright for headless testing?▼

Yes, it uses Playwright as the underlying engine for headless testing. It drives a persistent browser daemon via CLI commands, allowing you to automate interactions and gather state efficiently.

What is the best way to verify website behavior across deployments?▼

Verify website behavior by running automated QA workflows against a URL, then using snapshot and diff commands to gather state. This dogfoods the site across deployments with repeatable tests and visual evidence.

Why use a persistent browser daemon for automated QA testing?▼

A persistent browser daemon keeps state locally between commands, making automated QA testing fast and repeatable. It avoids the overhead of manual browser setup and ensures consistent interactions across test runs.
