Description

Finds elements by attribute name/value and highlights them on the page. Chrome extension for QA engineers who rely on `data-test` markers in UI testing workflows. It helps quickly inspect whether test attributes are present and correctly assigned on real pages, reduces time spent searching elements in DevTools, and speeds up selector validation during manual checks and automated test debugging. The extension finds elements on the active page by: - attribute name (required) - attribute value (optional) Then it highlights matching elements with your selected color and lets you navigate through matched elements with built-in focus controls. It supports **live mode**: new matching elements added to DOM are highlighted automatically via `MutationObserver`.
