Enzyme

Enzyme is a JavaScript Testing utility for React, designed to simplify the testing of React Components' output by providing methods to manipulate, traverse, and simulate runtime. Its API was influenced by jQuery, offering an intuitive way to interact with component trees. The last stable version released was 3.11.0, published in December 2019. Enzyme required specific 'adapter' packages (e.g., `enzyme-adapter-react-16`) to link with particular React versions. However, Enzyme is no longer actively maintained and has not received official updates or support for React 17, 18, or subsequent versions, due to significant changes in React's internal APIs. While unofficial community-maintained adapters exist for newer React versions, they are not officially supported and may have limitations. The project is effectively abandoned, and the React community has largely shifted towards `React Testing Library` for component testing, which promotes testing from a user's perspective rather than implementation details.
