FAQPage Schema
How do I capture desktop screenshots across macOS, Linux, and Windows for UI testing?▼

You can capture cross-platform screenshots across macOS, Linux, and Windows by specifying an output path, mode, and format. This ensures consistent visual references for UI validation and debugging.

Can I capture a specific screen region or active window instead of the full screen?▼

Yes, screenshot capture supports full screen, specific regions, active windows, and specific window IDs. You can configure these flexible capture options to isolate exact UI elements for regression testing.

How do I save automated screenshots to a temporary directory for ephemeral workflows?▼

Automated screenshots can be saved to a temporary directory by selecting the temp mode. This directs the output to an ephemeral location instead of the default OS save path for short-term UI checks.

Does this screenshot automation tool require any external dependencies?▼

No, this screenshot automation tool requires no external dependencies to run. It operates standalone using internal scripts to execute visual captures across different operating systems.

What is the best way to automate UI regression tests with exact visual references?▼

Automating UI regression tests requires capturing full screen or window-id screenshots with configurable output paths and formats. This generates exact visual references needed to track interface changes across platforms.
