Cypress-data-cy-highlight is a Chrome extension designed for developers and testers who work with web applications. This tool automatically highlights elements on a webpage that contain a data-cy attribute, making it easier to identify and interact with these elements during testing. The extension displays the value of each data-cy attribute, providing quick insights into the UI components being tested.

In addition to its highlighting capabilities, Cypress-data-cy-highlight allows users to export the highlighted elements to an HTML file. This feature is particularly useful for documentation and review processes, ensuring that all relevant attributes are captured and easily shareable. The combination of highlighting and exporting makes this tool an efficient addition to any developer's toolkit.
