FAQPage Schema
How do I automate QA testing with a headless browser from the command line?▼

Automating QA testing with a headless browser is done by driving a Bun-based CLI with Playwright. You execute deterministic commands like goto, click, and snapshot to navigate pages and verify interactions reproducibly.

Can I take annotated screenshots and visual diffs during automated browser testing?▼

Taking annotated screenshots and generating visual diffs are built-in features of this browser testing tool. You can use the snapshot and screenshot commands to document results and compare responsive layouts across deployments.

What is the best way to set up an AI agent for web app dogfooding and pre-release QA?▼

The best way to set up AI agent web app dogfooding is using a persistent browser environment that requires no manual setup. It provides a stable command surface for navigation, interaction, and reading content for pre-release QA.

Does Playwright work with Bun for navigating pages and testing dialogs?▼

Playwright works with Bun to execute deterministic browser commands for testing. You can navigate pages, test form submissions, handle dialogs, and interact with elements using a stable command surface.

How do I start testing a URL and labeling element references for automated QA?▼

To start testing a URL, initiate the process by using the goto command, then run snapshot -i to label element references. Finally, use the screenshot command to document the visual results of the interaction.
