data-qa Highlighter is a free Chrome extension developed by Alberto Vara. It falls under the category of Browsers and is specifically listed under the Add-ons & Tools subcategory. This extension is designed to assist QA and testing professionals who utilize the "data-qa" or "data-test" attributes in HTML elements.

The main purpose of data-qa Highlighter is to make the content of these data attributes visible on the screen. By simply clicking on the extension icon, users can visualize the areas in the screen where "data-qa" elements are located. This is extremely useful for professionals who need to identify and validate specific elements during their testing and quality assurance processes.

In addition, data-qa Highlighter provides two buttons for easy toggling of the highlighted elements. Clicking on the "HIGHLIGHT data-qa" button will display the data-qa/data-test elements on the screen, allowing users to easily identify and analyze them. Conversely, clicking on the "REMOVE data-qa" button will remove the highlighted elements from the screen.

To provide further convenience, the extension also shows the number of data elements found in the Document Object Model (DOM). In cases where no items are found, data-qa Highlighter offers a demo page link that allows users to test the functionality of the extension.

With its simple and straightforward functionality, data-qa Highlighter proves to be a valuable tool for QA and testing professionals who rely on data-qa or data-test attributes in their HTML elements. It streamlines the process of identifying and validating these elements, ultimately enhancing the efficiency and accuracy of quality assurance tasks.
