FAQPage Schema
How do I automate headless browser QA for site testing?▼

Automate headless browser QA by navigating pages programmatically, interacting with elements, verifying UI states, and capturing annotated screenshots to document visual diffs and generate bug reports.

Can I capture visual regression diffs across responsive layouts?▼

Yes, you can capture visual regression diffs by testing responsive layouts, comparing before and after states, and generating annotated screenshots to detect UI changes across different viewport sizes.

How do I verify UI states and dogfood user flows end-to-end?▼

Verify UI states and dogfood user flows by executing deterministic steps that navigate pages, interact with forms and dialogs, and capture evidence to validate end-to-end user workflows.

Do I need a local environment with a headless browser binary to run test scripts?▼

Yes, you need a local environment configured with a headless browser binary to execute the automation scripts, navigate pages, and capture evidence for your QA workflows.

What is the best way to capture annotated screenshots for bug reporting?▼

The best way to capture annotated screenshots for bug reporting is using a headless browser to navigate pages and interact with elements, automatically capturing visual evidence of UI states and failures.

Can I extend automation with custom scripts and references?▼

Yes, you can extend automation by applying custom scripts and references to navigate pages, interact with elements, and execute complex test flows beyond default site testing and regression checks.
