About

TestID Highlighter is a simple and effective developer tool that automatically highlights all elements that contain the data-testid (or dasta-testid) attribute.

This is especially useful for:

QA Engineers

Test Automation Engineers

Developers working with UI tests

Teams that use data-testid to mark testable UI elements

⭐ Features

Draws a clear dashed outline around all elements with test IDs

Automatically updates when the DOM changes (SPA support, React, Vue, Angular)

Works on all websites

Lightweight — no performance impact

Zero configuration required

🔒 Privacy First

This extension does not collect or transmit any data.
It only modifies the appearance of elements locally in your browser.

🛠️ How it works

A content script scans the page for elements with specific attributes and applies a CSS outline to make them visible for debugging or testing purposes.

Perfect for debugging selectors, inspecting test coverage and validating markup.
