browser-testing

Deterministic browser testing with Playwright is automated by driving navigation, interactions, and accessibility snapshots. The skill exposes tools like browser_navigate and browser_click to interact with pages and collect structured data rather than relying on pixel comparisons.

An accessibility snapshot for UI verification captures the current accessibility tree of a page. This provides deterministic structured data for validating that UI components render correctly after code changes, replacing fragile pixel-based comparisons.

Yes, you can use this skill for regression testing on a local development server. It automates navigation, form interactions, and element clicking, while automatically capturing console and network data for debugging workflows.

To interact with web elements, use the browser_snapshot tool to capture the page's accessibility tree, then use the browser_click tool with a known element ref. This method drives deterministic interactions without relying on visual coordinates.

Yes, you need Playwright installed at runtime to run automated UI tests. The skill requires Playwright to drive the browser, execute navigation, perform interactions, and collect accessibility snapshots for verification workflows.

Using an accessibility tree instead of pixel comparisons for web testing ensures deterministic results. It produces structured data that remains stable across minor visual changes, making CI verification and regression testing more reliable.
