Accessibility Bridge FAQs

Question 1

Does it require a separate browser installation?

Accepted Answer

No, Accessibility Bridge intelligently uses your existing Google Chrome installation via `puppeteer-core`, eliminating the need to bundle or manage a separate Chromium instance.

Question 2

How does it generate stable test selectors?

Accepted Answer

It leverages Chrome's computed accessibility tree and a Selector Priority Engine. This method generates selectors based on robust ARIA roles, accessible names, and semantic properties, making them resilient to visual redesigns and UI changes, unlike brittle DOM selectors.

Question 3

Which test automation frameworks does Accessibility Bridge support?

Accepted Answer

Accessibility Bridge generates framework-agnostic test selectors compatible with leading automation frameworks including Playwright, Selenium, Cypress, and WebdriverIO.

Question 4

What is Accessibility Bridge?

Accepted Answer

Accessibility Bridge is an MCP server that connects Claude Desktop to a live Chrome browser. It exposes the browser's full ARIA accessibility tree to Claude, enabling the AI to generate stable, framework-agnostic test selectors.

Question 5

Why use the accessibility tree instead of the DOM for selector generation?

Accepted Answer

The accessibility tree provides semantic meaning, reflecting how assistive technologies perceive a page. Selectors derived from it are inherently more stable, framework-neutral, and truly reflect user-facing intent, unlike DOM selectors that often target implementation details prone to breakage.
