enzyme-adapter-react-16-with-shallow-effects

enzyme-adapter-react-16-with-shallow-effects

This extremely-long-named package is a "fork" of the react-16 adapter included with enzyme, with one difference that applies only to shallow() testing:

- useEffect and useLayoutEffect hooks are supported, with dependency change tracking and cleanup support. See this enzyme issue for more information.

Also, under the hood, it uses react-shallow-renderer rather than react-test-renderer/shallow. Ongoing development of react-test-renderer/shallow has been moved to react-shallow-renderer. This should not result in any observable differences in behavior.
