Namespace: PuppeteerSharp.PageAccessibility

public interface IAccessibility

The Accessibility class provides methods for inspecting Chromium’s accessibility tree. The accessibility tree is used by assistive technology such as screen readers or switches.

Accessibility is a very platform-specific thing. On different platforms, there are different screen readers that might have wildly different output. Blink - Chrome’s rendering engine - has a concept of “accessibility tree”, which is than translated into different platform-specific APIs. Accessibility namespace gives users access to the Blink Accessibility Tree. Most of the accessibility tree gets filtered out when converting from Blink AX Tree to Platform-specific AX-Tree or by assistive technologies themselves. By default, Puppeteer tries to approximate this filtering, exposing only the “interesting” nodes of the tree.
