Attribute Scanner is a Chrome extension designed specifically for QA engineers and developers. It allows users to quickly scan and highlight elements on web pages based on custom attributes, such as data-cy, data-testid, and other user-defined attributes. This tool is particularly beneficial for those engaged in test automation, facilitating a more efficient testing process.

The extension offers features to highlight elements that possess specific attributes with a green outline, while also identifying interactive elements that lack these attributes with a red outline. This dual highlighting capability aids in pinpointing gaps in test coverage. Additionally, the tool is customizable, supports various attribute names, and requires minimal permissions, ensuring user privacy while enhancing the testing workflow.
