FAQPage Schema
How do I capture stable screenshots for visual regression testing across desktop apps and web pages?

To capture stable screenshots for visual regression testing, you need deterministic viewport handling and reproducible outputs. This ensures consistent UI state documentation across desktop apps, web pages, and simulators without manual rework.

Can I mask sensitive data when taking screenshots of web pages and simulators?

Yes, you can mask sensitive data when taking screenshots of web pages and simulators. The capture process supports region and element-level masking to secure confidential information while documenting UI state for QA verification.

Does screenshot capture work with both OS-level and Playwright-based environments?

Screenshot capture works with both OS-level and Playwright-based environments to ensure reproducible outputs. It supports cross-platform capture for macOS, Windows, and Linux across real and headless environments.

What is the best way to automate UI state documentation in CI for QA teams?

The best way to automate UI state documentation in CI is using cross-platform screenshot capture with configurable viewports. QA and design teams can snapshot UI to track visual regressions and communicate issues clearly.

How do I take a screenshot of a specific element or region instead of the full window?

To take a screenshot of a specific element or region, configure region capture during the screenshot process. This allows precise UI documentation by targeting specific application areas rather than capturing the full window.

Why do my web page screenshots look inconsistent during visual debugging?

Web page screenshots look inconsistent during visual debugging due to non-deterministic viewport handling. Achieving reproducible outputs requires stable capture configurations that lock viewport dimensions and rendering states across sessions.
