Enzyme Adapter Utilities

The `enzyme-adapter-utils` package (version 1.14.2, last published 2 years ago) serves as a foundational utility layer for developing and maintaining official and third-party Enzyme adapters. It provides common functionalities, abstract classes (like `EnzymeAdapter`), and helper methods necessary for an adapter to bridge Enzyme's API with specific versions of React or other UI component libraries (e.g., Preact, Inferno). Unlike the main `enzyme` package, `enzyme-adapter-utils` is not intended for direct use by application developers writing tests. Its primary consumers are the developers of `enzyme-adapter-react-*` packages. As an internal component of the Enzyme ecosystem, its release cadence is tightly coupled with major Enzyme releases and React compatibility updates. It enables the modularity of Enzyme, allowing it to support multiple React versions simultaneously without requiring a monolithic testing library. This package is crucial for ensuring Enzyme's continued compatibility with the evolving React landscape, although the broader Enzyme ecosystem faces challenges with newer React versions.
